Brief Summary of Minutes

Accomplishments

ALP-MAP-CAP Proficiency Programs<br /> <br /> The 2011 Agricultural Laboratory Proficiency (ALP) program enrollment has increase 12% over 2011, with 68 laboratories. The scope of analytical methods have increased to 128 analytical test methods with the inclusion of two new soil test methods. The ALP program has procured sixty-nine soils for future program cycles over the next four years. This includes new soil collections from Alaska, Montana, Michigan, Connecticut, and Maine. Since 2006 the program has collected and/or utilized soils from forty-six states and Canadian provinces. For 2011 ALP will be shipping five soils with one each representing the western, midwest, southeast and northeastern United States, with the fifth designated based on soil chemical properties. A test method for soil nematode analysis has been drafted for development of a future lab proficiency program. In conjunction with the Soil and Plant Analysis Council two laboratory workshops were conducted in the past year.<br /> <br /> The Manure Analysis Proficiency program has an enrollment of 65 labs enrolled and is administered by the Minnesota Department of Agriculture (MDA). The program is required for laboratories seeking formal certification of manure testing by MDA, and a requirement of NRCS Nutrient Management Code 590 and labs testing dairy manure in California. In 2009 the MAP program added electrical conductivity 1:5, nitrate analysis, extractable chloride and sulfate sulfur. These methods have been included to meet California Water Quality Control Board Requirements for Dairy Regulations. <br /> <br /> With support of the California Water Quality Control Board, the dairy manure nutrient management methods manual covering, soil and botanical analysis has been published, listed at: http://anlab.ucdavis.edu/docs/uc_analytical_methods.pdf. Authors are Holstege, Miller Meyer, and Price. Methods include: manure total nitrogen (two methods), P, K, NH4-N, Cl and SO4-S; soil NO3-N, total phosphorus, electrical conductivity and pH; and botanical total N, P, K and NO3-N. Each method is described in twelve sections, covering the scope of analysis, equipment, reagents, procedure, quality control, accuracy, safety and literature references. <br /> <br /> Arizona<br /> <br /> Research:<br /> A soil-applied zinc fertilization program for Arizona pecans.

Nasser, L. Longchamps, M. Moragues, S. Haley and R. Reich.<br /> <br /> Contact: Raj.Khosla@Colostate.Edu <br /> <br /> Active remote sensing has been documented as a means to improve nitrogen use efficiency (NUE) by improving rate and timing of N-fertilizer application. Recent literature discusses another promising way of enhancing global NUE by selecting crop genotypes that exhibit superior traits for NUE. The main objective of this on-going research study is to investigate the possibility of using active remote sensing to screen winter wheat (Triticum aestivum L.) genotypes based on NUE. <br /> <br /> Our study demonstrated that normalized difference vegetation index, as measured by GreenSeeker", allowed classification and identification of winter wheat genotypes that are superior in nitrogen use efficiency. Future research in varied environments would be needed to confirm the results of this study. Nevertheless this study demonstrates the potential for a new application of active remote sensing technology for screening crop genotypes exhibiting superior nitrogen use efficiency. <br /> <br /> <br /> Nutrients and Water Quality: A Region 8 Collaborative Workshop<br /> Salt Lake City, Utah February 15-17, 2011<br /> <br /> R.

Bauder<br /> <br /> Contact: reagan.waskom@colostate.edu <br /> <br /> Agencies and land grant universities in the six states of EPA Region 8 (CO, MT, ND, SD, UT, WY) hosted a three-day workshop on February 15 -17, 2011 to explore the science and institutional context regarding nutrients and water quality. The goal of the workshop was to build a better informed and more tightly linked community of nutrient researchers, regulators, managers, policy makers and stakeholders leading to collaborative approaches for developing and achieving nutrient controls and management. An online survey of workshop participants is being conducted to measure the impact of this program. Survey results, presentations, and a workshop report will be available at the workshop website: www.cwi.colostate.edu/nutrients.<br /> <br /> Organic Forage Management<br /> T. Hurisso, M. Booher, D. Goldhamer, D. Widiastuti, J. Brummer, F. Stonaker, M. Mikha, M. Stromberger, and J. Davis<br /> <br /> Contact: Jessica.davis@colostate.edu <br /> <br /> There are a limited number of organic forage producers in Colorado, thus organic dairies are faced with a shortage of high-quality, locally-produced organic forage. This study was conducted to determine how to optimize manure and compost use in organic forage production systems. The effect of raw and composted dairy manure on soil quality including soil aggregation, C and N pools, and earthworm abundance and distribution was evaluated within both annual and perennial production systems. <br /> <br /> A warm-season annual forage production system may provide growers with an opportunity to expand their markets while also providing dairies with a local source of organic forage; however, the issues of weed control and legume establishment must be rectified. Overall, the inclusion of manure or compost application can improve soil quality; however, tillage must be minimized in order for significant gains to be realized. The results highlight the importance of high quality (low C/N ratio) dairy manure in supporting higher abundance of endogeic earthworms; results also emphasize the importance of soil salinity as a potential limiting factor for endogeic earthworms when composted dairy manure is topdressed at higher rates on perennial forage. <br /> <br /> Regulated Deficit Irrigation (RDI) in Grand Valley Peach Orchards to reduce salt and selenium loading to the Colorado River.<br /> <br /> Denis Reich, Colorado Water Institute / CSU Extension Denis.Reich@Colostate.edu; Wayne Guccini, Mesa Conservation District.<br /> <br /> The Grand Valley of Western Colorado has been a focus area for reducing salt loading to waterways. Salts or Total Dissolved Solids (TDS) are flushed out of alkaline Mancos Shale soils by irrigation return flows. Salinity (the presence of salt) impacts the quality of downstream irrigation water and remediation of this problem has typically focused on improved irrigation efficiency through technology upgrades and improved Irrigation Water Management (IWM). These efforts have recently expanded to include selenium control, a contaminant that coexists with salt in soils but impacts aquatic life rather than downstream irrigators. <br /> <br /> Effect of Irrigation Water Salinity on the Yield and Quality of Watermelon and Muskmelon in the Arkansas River Valley. Michael E. Bartolo. Arkansas Valley Research Center, CSU Arkansas Valley Research Center. <br /> <br /> Contact: michael.bartolo@colostate.edu<br /> Watermelons and muskmelons are important fresh market crops in the Arkansas Valley of Colorado. Growers are increasingly using drip irrigation to produce these crops as a means to improve overall production. Concurrent with the conversion to drip irrigation, growers have switched to ground water for irrigation instead of the traditional surface water sources. Ground water is temporally more reliable than surface water and is relative free of particulates. Both characteristics make ground water more amenable for use in drip systems. Unfortunately, ground water sources contain 2 to 3 times the amount of soluble salts than surface waters. Our studies suggest that watermelon and muskmelon response to relatively saline irrigation water in the Arkansas Valley of Colorado may not be as detrimental as that predicted by other studies using waters that were more influenced by the presence of sodium salts. <br /> <br /> Idaho<br /> <br /> Ongoing Research:<br /> <br /> Corn<br /> Dr. Amber Moore, Steve Hines, and Christi Falen will continue to evaluate Nutri-Sphere N utilization by field corn, expanding to two Idaho locations (Parma and Kimberly) in 2011. <br /> <br /> Dr. Rick Lentz and Dr. Jim Ippolito are continuing to investigate the effect of biochar and other organic amendments on soil properties and nutrient uptake for corn and other crops.<br /> <br /> Potatoes<br /> Dr. Amber Moore and Dr. Jim Ippolito will evaluate the copper toxicity potential for potatoes grown on Idaho soils receiving dairy lagoon water applications through a greenhouse study. <br /> <br /> Sugar beets<br /> Dr. Amber Moore, Dr. Don Morishita, and Dr. Oliver Neher will continue to evaluate varying degrees of small grain residue level coverage and nitrogen placement (broadcast vs. shank) on sugar beet yield, quality, and nutrient uptake.<br /> <br /> Cover crops<br /> Dr. Amber Moore, Dr. Glenn Shewmaker, Christi Falen, and Lauren Hunter are conducting incubation studies to validate the Oregon State Universitys Cover Crop Calculator. This project is being conducted in cooperation with Dan Sullivan from OSU.<br /> <br /> Montana<br /> <br /> Ongoing Research<br /> Urea Volatilization  Drs. Rick Engel and Clain Jones are continuing to study ammonia volatilization from urea fertilizer and Agrotain. Preliminary results suggest that substantial urea volatilization occurs on soils near freezing (~20% loss) and losses are prolonged by Montanas lack of substantial precipitation following major urea application times (mid fall and early spring). A survey in MT, WY, and ID has been distributed to learn growers current N management practices that can affect volatilization, as well as learn current knowledge on the topic. WERA-103 participants, Drs. Amber Moore (ID) and Jay Norton (WY), assisted with this survey. This is a potential water quality issue depending on where ammonia deposition occurs.<br /> Overwinter Soil Nitrate-N Changes Drs. Jones, Robert Stougaard, Grant Jackson, Mal Westcott, Kent McVay, Chengci Chen, Joyce Eckhoff, Andy Lenssen, Perry Miller and Ms. Peggy Lamb finished up their 3-year study. The results from this research will allow those who fall soil sample to adjust soil N values in determining spring N fertilizer rates. On average soil nitrate-N increased overwinter suggesting using fall soil test levels will overestimate true N needs, yet nitrate losses of up to 60 lb N/ac were found suggesting N leaching. <br /> Cropping Systems  Drs. Miller, Chen, Buschena and Jones are studying the energetics of N fertilizer use compared to legume N contributions for a USDA-NRI grant. Drs. Perry Miller and Chengci Chen continue to investigate the effect of previous crop (legumes, brassicas, small grains) and crop rotation on N requirements and availability. Dr. Miller, Clain Jones, and Rick Engel are investigating N availability following pea and lentil green manures as part of USDA and state-level grants. Drs. Chen and Jones are studying the effects of tillage on N availability.<br /> Nitrogen fixation  Dr. Jones is finishing a study on the effects of legume green manure seeding and termination timing on N fixation in a field study. He is also evaluating the effects of phosphorus and mycorrhizae inoculation on N fixation in a greenhouse study. <br /> Precision Nutrient Management  Dr. Olga Walsh is investigating the effectiveness of optical sensors in assessing the need for topdress applications on small grains. Drs. Westcott and Ken Kephart are studying use of optical sensors for irrigated corn.<br /> Nitrogen Use Efficiency  Drs. Jones and Miller have been recently funded to measure nitrogen use efficiency for a range of MT cropping systems.<br /> Fertilizer source  Dr. Jackson evaluated effects of NSN and Avail on irrigated spring wheat and irrigated barley yield and quality. <br /> Nutrient  insect interactions  Drs. David Weaver, Jackson, and Jones evaluated effects of N and P on wheatstem sawfly cutting. <br /> <br /> New Mexico State University<br /> Accomplishments for multi-state NIFA report: Program development chaired by NMSUs Robert Flynn for the 2011 Western Nutrient Management Conference.<br /> <br /> Ongoing Research:<br /> Chile:<br /> Boron nutrition for chile.

Accomplishments

<b>Short-Term Outcomes</b><br><br /> WERA-103 successfully hosted the 2011 Western Nutrient Management Conference in Salt Lake City in March. Approximately 110 professionals from universities, industry and federal agencies attended the conference. Over 35 poster and oral presentations were made on topics related to nutrient management, cropping systems and water and air quality interactions. A large proportion of the presentations were made by graduate students, and awards were made for the top student presentations.<p><br /> In 2011, committee representatives wrote two nutrient management digest newsletters. These were widely distributed among nutrient management professionals in the western U.S. via an e-mail list serve.<p><br /> <br /> <b>Outputs</b><br><br /> Collectively, committee representatives reported publication of 77 refereed journal articles; 52 Extension publications; 38 proceedings and abstracts; 1 book chapter; 3 web sites; and 3 theses for a total of 174 publications focused on various aspects of nutrient management. A complete list of publications is included in the state report attachment.<p><br /> <br /> <b>Activities</b><br><br /> The main activity of the group was organization of the Western Nutrient Management Conference in Reno, Nevada. The conference occurred on March 3-4. The conference featured over 35 speakers and over 90 attending, including university, state and federal agency personnel and agriculture industry professionals.<p><br /> WERA 103 members worked with the International Plant Nutrition Institute to host the WERA 103 web site and archive minutes of meetings, proceedings documents, and other products of the committee. The site is currently under construction but will be located at: https://community.ipni.net/site/wera.nsf/events.xsp <p><br /> Members of the Committee agreed to write four articles for the American Society of Agronomys Crops and Soils magazine in 2012. This publication targets certified crop advisors and other agriculture professionals with timely information and recertification study/exam opportunities. The CSA News reaches 15,000 professionals across North America.<p> <br /> Committee members Amber Moore and Brad Brown of the University of Idaho developed the Western Nutrient Digest newsletter with contributions from WERA 103 members on nutrient management issues important to western U.S. agricultural systems. Two editions of the newsletter were published in 2011: http://www.extension.uidaho.edu/nutrient/newsletter.html<br /> http://www.extension.uidaho.edu/nutrient/pdf/Nutrient%20Digest_Fall2011.pdf<p><br /> <br /> The Committee continues to update the Western States Soil Testing Manual and makes this manual available in electronic or hard copy form at www.spcouncil.com.<p><br /> <br /> <b>Milestones</b><br><br /> WERA-103 members generated a master list of nutrient management extension bulletins in the western U.S. These publications address interpretation of soil and tissue tests for the purpose of making nutrient recommendations. The list serves as a reference and resource for committee members and agriculture professionals to seek out information on nutrient management practices. The list also ensures duplication is reduced and gaps in publications can be identified.<p> <br /> <br /> Committee members split into three groups to discuss progress since the last meeting toward each of the broad objectives outlined below.<p> <br /> 1) Develop and/or improve nutrient recommendations for diverse cropping systems based on soil, water and plant analysis results and management strategies in the Western Region.<br> <br /> a. Procedures for Objective 1:<br> <br /> i. Provide nutrient correlation and calibration data for crops in the region.<br> <br /> ii. Work toward uniformity of nutrient use recommendations for similar crop production systems in the region.<br> <br /> iii. Evaluate and apply new nutrient analytical and interpretive methodologies.<br> <br /> iv. Evaluate the efficacy of new fertilizers and formulations.<p><br /> <br /> Report<p><br /> Discussion Topic: What is the process of adopting new methodologies? Do emerging method must have some validity/repeatability prior to being placed on evaluation list?<p> <br /> 2012-2013 Objectives:<br><br /> - New model for nutrient recommendations: observational analysis. We need to evaluate how we come up with revised nutrient recommendations with past and limited or no new data, using spatially separated plots.<br> <br /> o Partner with private organizations<br><br /> - Recommending new methodologies for testing in seven labs (NAPT program). How do we as a regional committee recommend proficiency validation? We are not promoting the method; we just are saying there is sufficient interest that a method be evaluated. <br /> - Western Ag Labs nutrient availability probe method is recommended for evaluation by NAPT for proficiency validation with seven laboratories. Joan Davenport will recommend to NAPT.<p><br /> <br /> 2) Promote effective use of soil, water, plant, manure, and compost analytical information.<br> <br /> a. Procedures for Objective 1:<br><br /> i. Integrate analytical test results into nutrient management software<br> <br /> ii. Maintain and update the Western States Soil etc Testing Manual<br> <br /> iii. Review status of soil/plant/water analysis Extension guides and summarize interpretive guidance <br /> iv. Explore method for internet distribution of methods manual, analytical interpretation guides etc. Website would be for clientele outreach.<p><br /> <br /> Report<p> <br /> Need to make the Western States Soil Testing Manual more accessible to a wider audience<p><br /> o Entire manual available on-line: www.spcouncil.com (pdf or hardcopy)<br><br /> o Key methods (limited) for the West available for free WERA-103 site.<br><br /> o Joan Davenport to run WERA-103 website, update. Current WERA 103 website is community.ipni.net/site/wera.nsf/home.xsp<p><br /> <br /> 2012-2013 Objectives: Promote effective use of soil plant testing information<p><br /> - Integrate results into nutrient management software  Dan Sullivan<br /> regional nutrient management software<br> <br /> - Maintain Western Regional soil Testing manual<br><br /> -Review status soil water nutrient guides and publications. Develop one searchable database on WERA-103 website for all regional publications.<p><br /> <br /> 3) Provide education on the principles of soil-plant-animal-water system management and the tools and practices that lead to sustainable agricultural production.<br><br /> a. Procedures for Objective 3<br><br /> i. Facilitate regional education among government agencies, private industry and universities through conferences, websites, extension publications, newsletters, and other appropriate media. <br /> ii. Disseminate information within the Western Region to extension educators, private agencies (e.g., Certified Crop Advisors) and other interested parties (e.g., K-12 teachers) through conferences, training the trainer opportunities, and access to published interpretive materials.<br> <br /> iii. Conduct direct education to agricultural producers through conferences, grower meetings, and published interpretive materials.<p><br /> <br /> Report<p> <br /> - Discussion: How do we distribute the newsletter? WERA-103 Logo, Information about the committee and list of editors.<br> <br /> - Location: Univ. of Idaho website, WERA-103.<p><br /> <br /> 2012-2013 Objectives:<p><br /> <br /> - Facilitate website transition of WERA-103 website from OSU to WSU  Joan Davenport.<br><br /> o Update content on website<br><br /> o Increase visible<br><br /> - Niche articles inclusion in Newsletter? Can be included in one per Newsletter<br><br /> - Take proceedings authors to boil them down to have better readability for a wider audience.<br><br /> - What is our role for K-12 education? There are many organizations who have information on nutrient management. Provide links on website (e.g. Nutrient for life, ag in the classroom). If members have content, send to Joan for inclusion on website.<br /> <br /> <br /> <br /> <br /> <br /> <br />

Impact Statements

  1. The purpose of a WERA (Western Education/Extension and Research Activities) is to bring researchers together to coordinate related research without the need for a formal multi-state research plan, to organize technical conferences, work groups, task forces, or symposia for exchange of experience and opinions.
  2. The primary impact of the WERA-103 Committee has been to disseminate knowledge through the Western Nutrient Management Conference (biennial basis) for over 20 years. This conference brings agricultural professionals and industry members from the western region together to provide training and communication regarding nutrient management.
  3. The work of the WERA-103 committee has: 1) improved fertilizer use efficiency in the Western Region; 2) improved use of animal waste in environmentally safe ways; and 3)provided information to consultants and governmental agencies that can lead to less nutrient contamination of ground and surface water resources.

Brief Summary of Minutes

2013 WERA-103 Committee Meeting Minutes



March 6, 2013, 9 am - 5 pm



WERA-103 Committee meeting opened with opening remarks by David Tarkalson, WERA-03 Committee Chair and committee member introductions. The following committee members were in attendance:



Troy Bauder, Alan Blaylock, Sebastian Braum, Eric Bremer, Joan Davenport, Marko Davinic, Jonathan Deenik, Nat Dellavalle, Jason Ellsworth, Robert Flynn, Tim Hartz, Donald Horneck, Jim Ippolito, Clain Jones, Richard Koenig, Rob Mikkelsen, Bob Miller, Amber Moore (Vice Chair), Galen Mooso (Secretary), Dan Nelson, Stu Pettygrove, Dan Sullivan, Olga Walsh, Jim Walworth and Greg Binford (Visitor).



The following WERA-103 business items were discussed:



  • Galen Mooso, Secretary reported that all of the state reports except for Utah and Wyoming had been received and were printed for committee members and distributed to committee members in attendance.
  • Phyllis Pates was introduced as meeting site coordinator. Pre-registrations for 2013 Western Nutrient Management Conference (WNMC) were up for this conference compared to 2 years ago with 120 participants pre-registering. University attendance was about the same but industry participation was up with most of the increase coming from California. A copy of the WERA-103 financial statement with a proposed 2013 budget was provided. The 2011 ending balance was $11,465. The estimated revenue generated from the 2013 WNMC was estimated to be $2350. Logistics of the conference were discussed. A group of students from Fresno State University were in route with the poster boards for the poster session. Laptop computers and projector logistics for the sessions were finalized. It was suggested that because we will have two screens available that we should use both screens for the general session.
  • Stu Pettygrove, conference Chair, discussed some last minute details regarding the conference. Session Chairs are Alan Blaylock, David Tarkalson, Troy Bauder, Rob Mikkelsen and Jason Ellsworth. There are 32 presentations presented by 30 speakers and 19 posters on the conference agenda. Eight of the posters will be presented by students and will be in a student competition with cash prizes being presented during the luncheon on Thursday. Cash award money is provided by industry partners. CCA CEU credits will be available for each session with signup sheets are already prepared. Stu Pettygrove was thanked for putting together an outstanding conference.



Rich Koenig WERA-103 Administrative Advisor gave an update to the committee. Rich explained that he represents the western region Experiment Station and Extension Directors. One of his responsibilities is to make sure funds are being spent wisely. He updated the committee on how experiment station and extension funds are being reduced. He also reminded the committee that WERA-103 committee will need to resubmit a proposal in 2015 for continued existence. He recommended that a sub-committee be appointed at the 2014 committee meeting to prepare the resubmission necessary for continuing WERA-103 for another 5 years. He commended the committee for putting together an outstanding program for the 2013 WNMC which is the flagship activity of the committee. He said that he had been part of the committee since 1995. He said that he attended the very first WERA-103 committee meeting in 1993 in SLC, UT. Many of the faces have changed but there are a few people left from that original meeting. He noted that 2013 is the 10th WNMC organized by the committee. It is the desire to the western directors that this committee will continue to facilitate collaboration in the western region between university personnel and industry participants. The western directors have a competitive directors award ($10,000) that the give to committees to encourage collaboration in the region and suggested that the committee consider applying in 2014. There are some restrictions on the award money can be used. Award money cannot be used to fund speaker honorariums but can be used to fund other components of educational events and for someone to travel to the directors meeting to receive the award. Rich covered the following topic with discussion from the committee:


  • Ag research funding faces significant cuts. Some of the capacity funds may become more competitive in the future
  • Some discussion about extending the current farm bill beyond 2013.
  • The National Research Council will be reviewing Agricultural Food and Research Initiative (AFRI). There is some question about formula funding the future.



David Tarkalson led a discussion on Crops and Soils Magazine. Crops & Soils audience is 15,000 certified professionals. Article length: 1500 words or less. Images are encouraged in .jpg or .tif format, high resolution (at least 300 dpi); size = at least 3.5" wide. Images cannot be in Word and no copies from a web site. Deadlines: The magazine is published every 2 months, Jan-Feb, Mar-Apr. The articles for the next year are due to ASA on Apr 1, Jun 1, Aug 1, Oct 1, Dec 1, and Feb 1. The publication board relies on volunteer articles. A recent article from Montana State Univ. Minimizing urea volatilization in cool semi-arid regions was discussed as an example from the western region. The committee was asked who might like to submit article during the next year. The following volunteered articles of Crops and Soils:



  • 1) April 1- Alan Blaylock controlled release fertilizers based on information presented at 2013 WNMC
  • 2) June 1- Nat Dellavalle on fertilizer recommendations
  • 3) August 1 -Amber Moore work with an author out of a previous issue Nutrient Digest
  • 4) October 1- Bob Miller on effect of number of soil cores on soil sample analysis results
  • 5) December 1-Eric Bremer on correlation of resin probes to soil testing
  • 6) Feb 1- Amber Moore work with an author out of a previous issue Nutrient Digest



David Tarkalson said he will be responsible to follow-up with volunteers to remind them of the deadlines.



Bob Miller led a discussion regarding the poster session. There are 9 student posters (out of 17 total). The student posters will be judged in a competition by Bob Miller, Jim Ippolito, and Tim Hartz. Judges will be using the same form used for ASA student poster competitions. No specific time was scheduled to view the posters so time will be allotted during breaks and after the luncheon. Thanks to Fresno State students for delivering the poster boards for the poster competition.



David Tarkalson led a discussion to identify 2014 off year committee meeting location. Three possible locations were discussed:


  • Hawaii (2006 was the last time the WERA-103 committee meeting met there)
  • Columbia basin Washington
  • Ft. Collins Colorado (would probably need to be later than March)

After discussion regarding the 2014 WERA-103 committee location, a motion was made by Nat Dellavalle and seconded by Joan Davenport to meet in Hawaii during the 3rd week of March 2014. Jonathan Deenik agreed to host the committee meeting and recommended that we meet on the big island and he would put together an agriculture tour following the committee meeting.



Rich Koenig led a discussion on NRCS reliance on land grant university guidance for their 590 standard land grant university information. Rich expressed his concern that some of the information that the NRCS has included in their data base of nutrient recommendations is very dated and is no longer valid but is still being used. He indicated that NRCS and EPA have teamed up to put together a list of nutrient recommendations from all states. He expressed concern that if the list is not tied to a document that is current that the incorrect information could be used in nutrient recommendations. If documents are posted in a form like a .pdf document that information is not being updated but should be linked to a website where the information is being updated and is current data. He also has a concern that land grant universities may not have the data to support the 590 standards. He has heard from agronomists in the field that the recommendations are being misinterpreted in the field. There is an opportunity for the WERA-103 committee to work together to identify guidelines that work regionally. Need to identify gaps in the recommendations and determine if other adjacent states have the data to fill in the data gaps. There was discussion regarding the list of nutrient recommendations that Stu Pettygrove has complied for CA. Stu will pass on the information that he has collected on nutrient management in CA to Tim Hartz before he retires. Rich will report to the committee what WA decides to do with the request.



Amber Moore led a discussion on the Nutrient Digest, a quarterly WERA-103 publication regarding nutrient management issues. It covers research and extension subjects on nutrient management in the western region. Amber reported that the Nutrient Digest had received a $2000 grant from IPNI to help support the Nutrient Digest. Amber uses Susan to do the formatting and it usually takes about 10-11 hours per issue to formatting. A motion was made by Bob Miller that when the IPNI grant has been exhausted that the formatting costs be paid by WERA-103 funds. The motion was seconded by Joan Davenport. The motion passed. Amber thanked guest editors for their contribution to the newsletter. It is the responsibility of the guest editor to collect 4 nutrient management related articles and then edit them before submitting to Amber and Susan of formatting. Amber suggested that the guest editors branch out and include articles from other authors outside the WERA-103 committee. There are currently approximately 800 people on the email list. She encouraged those receive the newsletter to forward it on to others. The target audience is anyone interested in nutrient management which include CCA's in the western region. It was also discussed that it might be time for a facelift for the Nutrient Digest. Rob Mikkelsen indicated that IPNI can help with the facelift. Jason Ellsworth indicated that he also has graphic design resources to help with the face lift. It was determined that the WERA-103 committee site on the IPNI homepage also serves as a repository for the Nutrient Digest.



David Tarkalson led a discussion regarding the WERA-103 Website. IPNI is now housing website for WERA-103 committee. When you Google "Western Nutrient Management Conference" it links you to the following https://community.ipni.net/wera . Phyllis Pates has access to upload information to the website. Currently previous state reports, meeting minutes, and WMNC proceedings are on the website. Information regarding the 2013 WNMC meeting was also posted on the website. Joan Davenport and Allison were involved in getting the previous proceedings prepared to go onto the website. It was acknowledged that IPNI is a gold sponsor of the WERA-103 committee and they make their payment in kind through providing services to the committee by supporting the operation of the committee with Phyllis Pates time and talents. Thank you IPNI for all of your support.



Rob Mikkelsen led a discussion on "Agronomic data access: on-Farm/company database use and availability." There is currently in California legislation under consideration that will require California central valley growers to have nutrient management plans for their farms and the crops that they grow. Rob is aware of some companies that have services that track fertilizer applications for growers that may fulfill some of the reporting requirements. Jason Ellsworth indicated that Wilbur-Ellis has some data management ability that is part of their farmer services that will help track nutrient applications under a program called Ag Verdict. Galen Mooso indicated that Simplot has the ability to tract nutrient applications that is called Simplot Smart Farm. Rob indicated that these services will become more important to California growers in the futures at legislative mandates are finalized. This may be a topic for a future WMNC session.



Troy Bauder reported to the committee that funding for the old 406 Water Quality Committee has been slashed. A WERA group for water resources has been formed and will be meeting at Lake Tahoe June 14-15.



From 2:30 to 4 pm the committee was divided in to 3 breakout groups to review past tasks and identify specific tasks / projects that address WERA-103 Project objectives and procedures.



1) Develop and/or improve nutrient recommendations for diverse cropping systems based on soil, water and plant analysis results and management strategies in the Western Region.


  • a. Procedures for Objective 1:

    • i. Provide nutrient correlation and calibration data for crops in the region.
    • ii. Work toward uniformity of nutrient use recommendations for similar crop production systems in the region.

    • iii. Evaluate and apply new nutrient analytical and interpretive methodologies.

    • iv. Evaluate the efficacy of new fertilizers and formulations.


A new model for making nutrient recommendations using boundary analysis was discussed. This methodology can utilize survey data as opposed to replicated controlled experiments. A concern was expressed that there is no funding for the traditional calibration and correlation studies that have traditionally been used to make nutrient recommendations. Some corporate farms are so large that they are creating their own observational data sets. There was discussion about how can we use observational data improve existing fertility recommendations. To make good recommendations you need yield data that is related to environmental information. It may be useful to like yield data with plant tissue analysis. As possible topic for the 2015 WNMC is "How can we use observational data to improve nutrient management." Jim Walworth expressed interest in moderating this session. Bob Miller also expressed interest in being involved in this session. Prior to the meeting, Rich Koenig had emailed a master list for the western region on past and present fertilizer recommendations (see previous discussion item). There was discussion about a current emphasis with in NRCS on improving soil health. NRCS agronomist by the name of Ray Archuleta is making visits to western states talking about improving soil health by reducing tillage. He has several presentations on YouTube. There was also discussion about evaluating the efficiency of new fertilizer products and technologies. There is confusion about how products get approved for incentive NRCS/USDA programs. NRCS seems to rely heavily on land grant university data when land grant universities are not necessarily testing all products. There is no minimum performance level. There is no consistency form state to state. Who's job is it to evaluate the efficiency of fertilizer products for efficiency? Does there need to be a clearing house for non-traditional soil amendments? There was also some discussion about a new Solvita test for soil health which measures soil respiration and there was concern that on western soils that it may not correlate to N mineralization.

2) Promote effective use of soil, water, plant, manure, and compost analytical information.

  • a. Procedures for Objective 1:

    • i. Integrate analytical test results into nutrient management software
    • ii. Maintain and update the Western States Soil etc. Testing Manual
    • iii. Review status of soil/plant/water analysis Extension guides and summarize interpretive guidance
    • iv. Explore method for internet distribution of methods manual, analytical interpretation guides etc. Website would be for clientele outreach.



This group discussed the question "How do you integrate analytical data into fertilizer recommendations?" They discussed Biological Nutrient Program developed by OSU to predict N mineralization by organic N sources. Crop Manager is a program developed by the California system to schedule irrigation applications and N applications. Crop Time is another tool developed by OSU to predict growing degree days. Western Labs out of Canada has commercialized resin probes to predict nutrient availability. Tim Hartz will be the keeper of Stu Pettygroves data base that he has developed over the years. Bob Miller indicated that the revision of the 2005 Methods Manual is complete and under review. Meleich 1 and 3 methods were removed from the new edition.



3) Provide education on the principles of soil-plant-animal-water system management and the tools and practices that lead to sustainable agricultural production.


  • a. Procedures for Objective 3

    • i. Facilitate regional education among government agencies, private industry and universities through conferences, websites, extension publications, newsletters, and other appropriate media.

    • ii. Disseminate information within the Western Region to extension educators, private agencies (e.g., Certified Crop Advisors) and other interested parties (e.g., K-12 teachers) through conferences, training the trainer opportunities, and access to published interpretive materials.

    • iii. Conduct direct education to agricultural producers through conferences, grower meetings, and published interpretive materials.



Present- Robert Flynn, Markova Davinich, Troy Bauder, Joan Davenport, Clain Jones, Rob Mikkelsen, Amber Moore.



Ongoing efforts: Nutrient Digest. Follow up to make certain that it gets onto website front page (Amber follows up)



Web Site: fix home page setting, also hot link to the objectives under Western Director/NIMSS page (Clain will follow up).



There will be hot link the PDFs from the conference proceedings to the paper titles (Robert Flynn follows up)



Develop a section of photos from past meeting tours. Joan will send out request of annotated photos and strive to have gathered for next meeting (2014).



Add news flashes, as a blog, to have pertinent soil nutrient issues highlighted (Marko follows up)



K-12 and other Education: Our target is STEM teachers, FFA, Master Gardeners. We have a long laundry list of potential ideas for education. We would like to have a Western States spin on this. To facilitate this, we are proposing developing lesson plans and video record the demonstrations at the next meeting (2014). To do items are send out request for lesson plans/ideas in Sept (Rob M.) and indicate what people are bringing for taping during the 2014 meeting ( commit by Mid Jan 2014).Topics mentioned are:



  • Soil Quality Test Kit

  • Sponge Demo

  • 2 L bottle soil erosion

  • Effervescence

  • CEC with Dixie cups and Kool Aid

  • CEC with balloons and colored paper

  • Soil biology candy lab



4:00-5:00pm WERA 103 Member Reports were presented. See state reports for details.



Action Items



1) WERA-103 Secretary will submits an annual report on the committee activities to NIMS within 60 days of the committee meeting which will include a list of participants, state reports, committee meeting and an executive summary. Rich will send Galen the information necessary to make sure that the report can be submitted in a timely manner.



2) At the 2014 committee meeting a sub-committee needs to be appointed that will revise the WERA-103 proposal for submission in 2015 to continue the committee activities for another 5 years.



3) 2014 Directors Award applications are due by March 10, 2014. A sub-committee of Amber Moore and Rob Mikkelsen was decided. This sub-committee will need a reminder on approximately January 1, 2014.



4) Discussion item for the 2014 committee meeting "Where does the committee draw the line of presentation of information on proprietary productions and information?" The question was prompted by a poster submitted by Solivta which has a test that they are selling for biologically active carbon. The poster ended up being not presented because he author is no longer with the company. Guidelines should the recommended for the presentation of information that may not have a scientific component.



5) 2015 WNMC committee needs to make sure there is a time slot scheduled for viewing posters.



6) Item for discussion at the 2014 committee meeting is "What kind of presentations should be expected to provide a manuscript for the proceedings?" Should we expect a manuscript when the presenter is part of the CCA presentations?

Impact Statements

  1. The purpose of a WERA (Western Education/Extension and Research Activities) is to bring researchers together to coordinate related research without the need for a formal multi-state research plan, to organize technical conferences, work groups, task forces, or symposia for exchange of experience and opinions.
  2. The primary impact of the WERA-103 Committee has been to disseminate knowledge through the Western Nutrient Management Conference (biennial basis) for over 20 years. This conference brings agricultural professionals and industry members from the western region together to provide training and communication regarding nutrient management.
  3. The work of the WERA-103 committee has: 1) improved fertilizer use efficiency in the Western Region; 2) improved use of animal waste in environmentally safe ways; and 3)provided information to consultants and governmental agencies that can lead to less nutrient contamination of ground and surface water resources.

Report from WERA-103 Advisor

Rich Koenig (WERA-103 Administrative Advisor) gave a committee update. He indicated that our project renewal, which is due every five years, expires 31 Sept 2015. Effectively it is due (submit reauthorization) Jan 2015. Joan Davenport (lead), Rob Mikkelsen, Bob Flynn, and Galen Mooso volunteered to develop the new project. Rich also covered the NIFA list of the AFRI funding priorities and the group that NIFA has removed the match requirement for USDA-ARS and Land Grant Universities. Climate hubs are being developed and these will be important to be aware of. A map and web address with information about this project will be provided.



Planning for 2015 Western Nutrient Management Conference

The dates for the meeting were identified as 4 March 2015 for the WERA-103 business meeting and holding the conference on 5 & 6 March 2015. Phyllis Pates confirmed that the facility is available on these dates.



David Tarkalson volunteered to be the meeting chair and Grant Cardon the vice chair.



Topics Identifed for the Conference were:

Nitrogen budgeting and fertilizer use reporting – the future of agriculture?

Salinity (including sodicity and B)

The effect of drought on nutrient management

Micronutrients (CCA?)

How does soil fertility intersect with soil health

The role of cover crops in nutrient management





Olga Walsh volunteered to coordinate the poster session including the graduate student poster contest.



There was a discussion about the Leadership Award presented at the conference. As chair of the Executive Committee, Galen Mooso will solicit nominees and the Executive Committee will determine the awardee based on merit. Bob Miller is compiling a list of past recipients and the plan is to include this on the revised web site.



There was a 1/3 return rate of surveys from the 2013 Conference. The overall ratings were 31 very good; 10 good; 2 ok. Concern was expressed over the rate of survey return. Grant Cardon and Amber Moore volunteered to determine how best to increase the rate of return of survey, including looking into electronic survey options. Other information suggested to include is the state attendees came from, how attendees travelled to the conference, and if an attendee is or is not a CCA. The surveys also confirmed that the format worked well with a session plenary session followed by then two concurrent CCA and research topical session.



Financial Report:

This was presented, with a motion to approved (Joan Davenport), seconded (Bob Miller) and unanimously approved. The group extended our thanks to Phyllis Pates of IPNI, and to all of our sponsors, including IPNI, for their support of the Western Nutrient Management Conference.



A detailed discussion took place with respect to the location of the next Western Nutrient Management Conference. There were comments in the attendee survey suggesting different locations. Grant Cardon reviewed the attendee numbers from past conference, which showed a clear pattern of decline for the last 3 meetings held in Salt Lake City and a clear pattern of increased attendance since moving to Reno. The data also showed that we are reaching a greater number of Certified Crop Advisors. Alan Blaylock moved, seconded by Nat Dellevalle, that the meeting be held in Reno, which passed unanimously.



Other Topics:

Bob Miller provided copy of 50 potential logos for the WERA-103 group, all of which are original and not trademarked. These were circulated and members chose their top 3. The group chose (by 12 votes) logo #9 and Bob will move forward on this.



David Tarkalson reviewed the WERA-103 contributions to Crop and Soils Magazine. We submitted 3 in 2013 and one in 2014 to date. Amber Moore volunteered to help provide a list of topics from those the group already develops for the Western Nutrient Digest.



There was a long discussion on the WERA-103 website. David Tarkalson volunteered to work with Phyllis Pates to upgrade the information on the website. Items to include are a link to the NIMMS website, links to past proceedings and a box within that of poster award winners.



A recent publication (Khan, S. A., R. L. Mulvaney, and T. R. Ellsworth. 2014. The potassium paradox: Implications for soil fertility, crop production, and human health. Renewable Agriculture and Food Systems 29:3 – 27) was discussed at length. As a group, we recognize and agree that there are issues with soil testing and nutrient recommendations for potassium management. However, the group concluded that the article skipped key points such as “How does this relate to crop deficiencies? What is appropriate testing (soil, tissue, other)? What other testing issues should be considered (e.g., soil sampling depth, wet or dry sample for testing, soil moisture, crop removals and removal of crop, saturated paste extracts). Several conferences will be addressing the topic, including one mentioned sponsored by the IPNI and a session on K soil test the International Soil and Plant Analysis conference in Jan 2015.
We closed this discussion concluding that we should revisit progress on this topic at 2015 WERA-103 Meeting.



A long discussion ensued about the direction that the NRCS is taking towards promoting and possibly implementing testing for soil health. A committee composed of Grant Cardon, Bob Miller, Troy Bauder, Jim Walworth, Dan Sullivan and Jonathan Deenik was formed to draft a position statement that expresses our concerns about how the proposed tests address issues of soil health in the arid and semi-arid areas of the Western US.

Accomplishments

<b>Short-term Outcomes:</b><br> <br /> Grant Cardon of Utah State University developed a program on exploring how soil test interpretation and recommendations were developed using real data. This will be shared with the group for use throughout the region.<p><br /> <br /> A recent survey by the International Plant Nutrition Institute (IPNI) reported that Land Grant Universities and the Extension Service were rated #10 as farmers source for information (family members #1), with a very high rating for trust in the information provided.<p><br /> <br /> New Mexico State University and Utah State University have developed programs where county agriculture extension agents working with prison inmates, much like Master Gardeners, including growing plants.<p><br /> <br /> All states reported efforts on soil and water nutrient management in different educational outreach formats, including You Tube, work with STEM organizations, Master Gardener education, University education, CCA education, and working with county extension personnel to expand educational outreach.<p><br /> <br /> <b>Outputs:</b><br> <br /> Four articles were submitted to and published by Crops & Soils Magazine authored by and covering topics from the WERA-103 group.<p><br /> <br /> The “Western Soil and Plant Analysis Methods” book has been reviewed and updated.

Impact Statements

  1. <b>Activities:</b> The WERA-103 website is hosted through the IPNI. Work is needed to increase how readily this can be found and improve its content. Committee member David Tarkalson will be working with IPNI?s Phyllis Pates to content and visibility. Specific items are: 1) include past award winners; 2) link to NIMMS site; 3) link to past proceedings; 4) box in each year proceedings to list grad student poster winners (and poster titles).
  2. <b>Milestone:</b> There are several testing methods that are interested in being included in the Soil, Plant, and Irrigation Water Methods for the Western Region Handbook. We as a group are requesting calibration data to include the methods.
  3. <b>Milestone:</b> Concern over the ?Soil Health? testing procedures for being promoted by the Natural Resource Conservation Service (NRCS) were raised. The groups concern is two-fold - one is with lack of calibration of potential testing methods and the other is with suitability for the arid and semi-arid regions of the western US. The group has agreed to develop a position statement on this to share with the NRCA.
  4. <b>Activity:</b> In addition, the topic of ?Soil Health? testing procedures being promoted by the NCRS has been included in the 2015 Western Nutrient Management Conference as well as in the upcoming (January 2015) International Soil and Plant Analysis Conference in Kona (Hawaii).
  5. <b>Indicators:</b> Updates at the meetings included not only activities by state, but the collaboration between public and private sector members of the committee. Partnerships are formed and research and extension efforts are provided with economic support from the industry collaborators in the form of in-kind materials, reduced prices on services, and when appropriate, donations to research programs.

Brief Summary of Minutes

Report from WERA-103 Advisor; Question and Answer (Rich Koenig):

State land grant schools are committed to allocate money to multi-state activities, one of which is WERA-103. Experiment Station Directors must approve renewal of multi-state projects every five years. WERA-103’s current approval ends September 30, 2015. Application for renewal for the period of October 1, 2015 to September 30, 2020 has been submitted. Proposal goes into NIMSS system. Experiment Station Directors will make a decision on the renewal application at their April, 2015 meeting in Portland, Oregon. Their recommendation will be forwarded to NIFA and an announcement regarding the application is expected in July or August, 2015.



Rich noted that having official industry representation is beneficial to the approval process. Rich mentioned that each state has at least one official representative who receives AES funds to travel to the meeting, but some have more than one. It is advantageous to reach out to other researchers in other states to encourage participation in the WERA 103 activities. Rich encouraged us to think about other ways besides the biennial conference the regional project could be effective to facilitate collaborative grant proposal and use expertise around the table to produce outputs that could potential influence policy, such as white papers on a particular topic. Soil health was brought up as an example of a topic that the group could provide science toward. Discussion followed. Rich mentioned that there is a lot of turnover at college level and don’t be surprised to see new faces.



The current membership list is not up-to-date. There are 24 registered members. Some industry members are not signed up, at least some due to problems in NIMSS. Rich will work with Ellen Yeates to straighten this out.



There was a discussion of WERA-104 committee composition. States can have more than one representative (and several do), but Experiment Stations are not committed to providing funding for more than one representative. Non-land grant university representatives are permissible (we have one from Brigham Young University) and it was agrees that we should consider inviting representatives from additional non-land grant schools. In addition, additional industry representation was discussed. It was agreed that more industry involvement is desirable, but that we must be careful to 1) make sure the industries are truly involved in nutrient management and 2) that we should be cognizant of practical committee size limitations. Discussion of establishing membership guidelines followed. No decision on writing or adopting guidelines was made, buy this will be a topic at the 2016 meeting.



The Western Nutrient Management Conference continues to be successful. The move to Reno, Nevada has improved attendance, particularly by consultants.



The groups could do more work on multi-state and university-industry grants.



The group could consider writing position papers on important policy items such as Cover Crops, or Soil Health. The current NRCS emphasis on soil health was discussed and concerns were noted regarding the de facto adoption of soil health standards, exemplified by the Haney test, in light of the lack of field testing and validation data. The committee consensus is that WERA-103 could make valuable contributions via production of white papers. There was also agreement that inclusion of NRCS representation in WERA-103 would be desirable.



There is an annual Experiment Station recognition award with a $5,000 monetary award that WERA-103 could apply for. The deadline for 2015 has passed. We would have to apply in the fall of 2015.



Treasurers Report (Phyllis Pates):

A treasurer’s report was submitted. Major points were:


1. Attendance in 2013 was 129, up over 62 to 90 of the previous four conferences. 2015 attendance is expected to be similar to 2013.

2. WERA-103 has a current bank balance of $15,564.38



Alan Blaylock asked about contingency money should the conference have a bad year due to weather or other reasons for low attendance. Discussed followed around creative ways to utilize some of the balance, especially if continues to rise. These included travel support for speakers or other activities for the committee. There was discussion of the registration fee ($125) which has not been changed in several years. Conference registration fees will be revisited at the 2016 meeting.



2015 Western Nutrient Management Conference overview and final details (David Tarkalson):

Don Horneck will be the recipient of the Leadership Award. Donations are being accepted to an Oregon State University scholarship in his name.



A significant number of WNMC presenters did not submit paper as required. There was a discussion about whether or not we should require papers. Some felt an abstract is sufficient, although several noted that the full papers provide a record of the meeting and a valuable resource that can be studied to provide more detail than can be gained during an oral presentation. Additionally, the existence of dual sessions at the WNMC makes it impossible for attendees to hear all talks. Full papers provide information of missed talks in parallel sessions. The exercise of preparing a full paper is also a valuable experience for student presenters. The conference proceedings and paper format should be a topic for the 2016 meetings.



Crops and Soils Magazine contributions:

We should provide an article for each of the bi-monthly issues. They can be adapted from Nutrient Digest articles. There are also regional issues with longer feature articles. David Tarkalson will inquire about the date of a Western issue. Commitments for 2015:


  • David Tarkalson – Nitrogen in sugarbeets
  • Grant Cardon – Nitrogen in corn following alfalfa
  • Jay Norton – Dryland winter wheat
  • Clain Jones – Nitrogen management
  • Jonathon Deenik – Nutrient management in remote populations
  • Joan Davenport – Late season N in grapes



2015-2016 WERA-103 Executive Committee:


  • Joan Davenport, Chair
  • Jim Walworth, Vice-chair
  • Troy Bauder, Secretary



2016 WERA-103 meeting:

Will be held in Colorado, either Denver or Fort Collins area, Bob Miller and Troy Bauder will host.

Accomplishments

<b>Objective 1: Develop and/or improve nutrient recommendations for diverse cropping systems based on soil, water and plant analysis results and management strategies in the Western Region.</b><ul> <br /> <li>a. Provide nutrient correlation and calibration data for crops in the region. <br /> <li>b. Work toward uniformity of nutrient use recommendations for similar crop production systems in the region. <br /> <li>c. Evaluate and apply new nutrient analytical and interpretive methodologies.<br /> <li>d. Evaluate the efficacy of new fertilizers and formulations.</ul><p><br /> <br /> Many nutrient recommendations are based on dated calibration data collected from studies using old cultivars and no-longer used farming practices. We should focus on regional collaborations, combining information for specific crop growing areas. Examples include the potato region of Idaho, Washington, and Oregon, and the pecan area of New Mexico and Arizona. Collaborations should include formation of working groups, improved communication, and regional recommendations and publications. Current collaborations include joint calibration studies on nitrogen, phosphorus, iron, and nickel on pecans produced in Arizona and New Mexico and sharing data between these two states. Joint extension publications are in preparation.<p><br /> <br /> New analytical protocols are being adopted, but with little or no field calibration. Specifically, soil health tests (the Cornell Soil Health Assessment and the Haney Soil Health Test) are being adopted by soil testing labs and used by the NRCS despite lack of field evaluation. The need for improved nitrogen mineralization predictions are widely recognized, but it is unclear that the soil quality concept or the specific tests mentioned provide this. It is recommended that committee members conducting nutrient (particularly nitrogen) studies include an evaluation of the Haney test.<p><br /> <br /> Relevant research:<ul><p><br /> <br /> <li>ARS projects in Idaho. <br /> <li>In New Mexico, preliminary work on initial soil samples and cover crop trials and measurements. <br /> <li>Projects in Wyoming collaboration with state agronomist evaluating traditional and Haney soil tests.<br /> <li>Mixed cover crop study in Montana comparing Haney test and winter wheat yield the following year.</ul><p><br /> <br /> WERA103 is exploring the possibility of producing a white paper on soil health and soil health assessments. WERA103 members are individually communicating with state NRCS personnel to make sure new procedures are adequately vetted <i>before</i> widespread adoption. For example, WERA-103 members Tim Hartz, Dan Sullivan, Clain Jones, Jonathan Deenik, and Jay Norton have met with Western States NRCS agronomists to develop avenues for communication and cooperation on these issues.<p><br /> <br /> There is a need to compile and make available existing data. Bryan Hopkins compilation of Avail studies, results of which were presented at the 2015 Western Nutrient Management Conference, is a great template. WERA-103 members could consider finding funding for personnel to do this work and exploring ways to communicate the resulting information.<p> <br /> <br /> <b>Objective 2: Promote effective use of soil, water, plant, manure, and compost analytical information.</b><ul> <br /> <li>a. Integrate analytical test results into nutrient management software <br /> <li>b. Maintain and update the Western States Soil etc Testing Manual <br /> <li>c. Review status of soil/plant/water analysis Extension guides and summarize interpretive guidance<br /> <li>d. Explore method for internet distribution of methods manual, analytical interpretation guides etc. Website would be for clientele outreach.</ul><p><br /> <br /> <br /> Plans were made to revise the Soil, Plant and Water Reference Methods for the Western Region (2005 3rd Edition) to develop better guidance documents to cover uses and pitfalls of various soil test methods. The revision will be designed for someone who wants to understand the use of a test without having to work through the methods. We will begin with phosphorus: evaluate pH limits on use of P tests, correlation of extracts to one another, and accuracy of results at a range of concentrations. SSSA soil analysis methods books will be utilized where possible. The format will follow the Western Fertilizer Handbook. Dan nelson will be in charge of this effort. A session will be developed for the next WERA 103 conference reviewing the results of this work.<p><br /> <br /> <b>Objective 3: Provide education on the principles of soil-plant-animal-water system management and the tools and practices that lead to sustainable agricultural production.</b><ul> <br /> <li>a. Facilitate regional education among government agencies, private industry and universities through conferences, websites, extension publications, newsletters, and other appropriate media. <br /> <li>b. Disseminate information within the Western Region to extension educators, private agencies (e.g., Certified Crop Advisors) and other interested parties (e.g., K-12 teachers) through conferences, training the trainer opportunities, and access to published interpretive materials. <br /> <li>c. Conduct direct education to agricultural producers through conferences, grower meetings, and published interpretive materials.</ul><p><br /> <br /> Educational materials and outputs supporting this objective include:<p><br /> <br /> <b>Publications:</b><p><br /> <br /> One-Time Summer Tillage of Chemical Fallow in Dryland Winter Wheat Rotation Does Not Negate Long-Term Benefits Accrued Under No-Till Management.

Impact Statements

  1. <b>Activity:</b><br>The WERA-103 website is hosted through the IPNI (http://www.ipni.net/wnmc), and is now much more highly visible and provides easy access to the WNMC program, a list of poster titles, information on the WERA-103 committee composition, and Proceedings from the past three conferences. It also includes the Western Nutrient Digest, which is published as part of WERA-103 activities. Further expansion of the website may include: 1) past award winners; 2) links to NIMMS site; 3) grad student poster winners.
  2. <b>Activity:</b><br>One hundred and thirty people, including 40 Certified Crop Advisors, attended the Western Nutrient Management Conference, March 5-6, Reno Nevada, where they received science-based training in nutrient management. In addition to the topics that were covered (shown below), a survey was conducted to determine in what subjects the attending nutrient management professionals would like to receive additional training.
  3. <b>Activity:</b><br>A Regional WSARE project has been funded to improve technology transfer to clientele: Developing Digital Tools to Improve Soil Sampling and Analysis for Sustainable Agriculture in the Western U.S. New Mexico State University, Colorado State University, Washington State University, and University of Arizona.
  4. <b>Milestones:</b><br> There are continually new testing methods for consideration of inclusion in the Soil, Plant, and Irrigation Water Methods for the Western Region Handbook. We as a group are pushing for calibration data to include the methods. As an example, there is interest by the Natural Resource Conservation Service (NRCS) to adopt ?Soil Health? testing procedures, however there is a lack of calibration of testing for these methods, and questions about their suitability for the arid and semi-arid regions of the western US. WERA-103 has initiated discussions with state NRCS personnel to promote rigorous testing prior to widespread adoption of these techniques. Further, the group has agreed to develop a position statement on this to share with the NRCS and other interested groups.
  5. <b>Indicators:</b><br> Updates at the meetings have included not only activities by state, but the collaboration between public and private sector members of the committee. Partnerships are formed and research and extension efforts are provided with economic support from the industry collaborators in the form of in-kind materials, reduced prices on services, and when appropriate, donations to research programs.
