Statement of Issues and Justification

Plant nutrients are essential for the profitable and sustainable production of food, fiber, and bio-energy. Agricultural producers, consultants, and regulators all require accurate and up-to-date nutrient requirements and management information to make intelligent decisions.



Nutrient management in the Western Region is becoming increasingly important because of the need to maintain or increase productivity, to maximize resource use efficiency, to protect ground and surface water resources, and to ensure the long-term health of soil. When improperly used, nutrients have been implicated in decreased soil, air, and water quality, as well as reduced profitability, productivity, and water use efficiency.



Many specific management options can be implemented to improve the way nutrients are used. Best Management Practices (BMPs) are being developed for crops throughout the West to maximize nutrient use efficiency and to reduce adverse environmental impacts. Federal agencies, state Land Grant institutions, and private industry work cooperatively to identify and reduce the potentially negative impacts of poor nutrient management on economic and environmental sustainability. Since these issues are more related to cropping systems and regional conditions than to state-line boundaries, regional cooperation is needed to develop reliable, consistent, science-based recommendations. Information sharing on a region-wide basis improves accuracy and efficiency, and reduces duplications of effort and inefficient use of resources. Regional efforts apply more broadly than individual localized ones. This project has provided and continues to provide a unique and powerful educational forum for scientists, industry representatives, governmental agencies, and consultants to engage in dialogue concerning nutrient management issues.



BMPs are being developed by scientists for implementation across public and private sectors. A re-evaluation of current nutrient management practices and the development of improved techniques to determine specific crop nutrient requirements provide the foundation for increasing efficiency and profitability of nutrient use and improving soil, water, and air quality. Additionally, quantifying the fate of nutrients in unmanaged ecosystems provides important insight to processes occurring in managed agricultural soils. The use of organic nutrient sources, such as manure and compost, also pose challenges to efficient utilization and environment protection. Accurate soil, water, and plant analytical information is essential for making wise nutrient management decisions. This information is increasingly required for establishment of environmental regulations and for compliance to environmental standards. The cooperation and continuing education of analytical labs offering agricultural services and agricultural consultants is important for providing accurate information to local decision makers. Outputs from this project provide a sound footing for decisions by industry, government, producers, and scientists.

Objectives

  1. Refine and improve nutrient recommendations based on soil, water, and plant analysis for efficient crop production and nutrient use, promoting responsible use of nutrients, and minimizing environmental impact in the Western Region.
  2. Develop and promote strategies for sustainability of soil, water and air resources - improve and sustain soil conditions (e.g. organic matter, soil health, salinity, nitrate levels) and air and water quality through management approaches such as efficient use of fertilizer, manure, compost, biological amendments, cover crops, reduced tillage, and efficient irrigation management in Western cropping systems.
  3. Provide education and outreach on the principles of soil-plant-animal-water systems function and management, and the tools and practices that lead to sustainable agricultural production.

Related, Current, and Previous Work:



Research relating to nutrient use efficacy is conducted throughout the region. Through this regional group, current information is relayed to diverse users including crop consultants, government regulators and agencies, industry, and university researchers. Recent biennial Western Nutrient Management conferences were held in Reno, Nevada in 2011, 2013 and 2015. This forum extended information on topics ranging from 1) nitrate management and regulatory status, 2) evaluations of nitrogen crop demands, fertilizer formulations, mineralization, leaching, volatilization, and monitoring 3) water and salt management to soil, manure, and plant testing, 4) data analysis techniques for field studies, and 5) specific crop nutrient recommendations. This is a major conduit for bringing current research and policy information to user groups.

Educational Plan

The educational component of WERA-103 will focus on delivery of the latest nutrient management information and other technology to educators, industry agronomists, government agencies, and other interested parties. This will be done through regional publications, regional conferences, web-based bulletins, and other web based outlets such as educational videos, short courses and podcasts.



The past efforts by this group include holding the biannual Western Nutrient Management Conference (WNMC) which involves university, government and industry personnel sharing their findings, addressing and responding to emerging issues and interacting with a large group to expand the bidirectional understanding of the regional needs. The WNMC also fosters additional cooperative research and extension efforts.



Coordination with the North American Proficiency Testing Program and generating associated publications will educate the agricultural industry about continued advances in soil and plant analysis that are calibrated and scientifically rigorous, to support soil and plant analysis programs across the region.



Planned publications outlined in Methods will support state faculty and industry personnel in their ongoing educational efforts in nutrient management and water quality. The coordinated efforts of the groups producing these publications will help focus research efforts on those areas where additional data is needed and the working group forum ensures the regional nature, scientific rigor, and combined industry and extension promotion of sound, science based practice throughout the region.

Organization/Governance

The Committee Chair provides leadership for the committee and is responsible for coordination with the Western Directors, and for planning the annual meeting. The Committee Chair Elect provides support to the Chair and becomes the Chair the following year. The Secretary is responsible for submitting minutes and state reports from annual meeting and becomes Chair Elect. Officers serve for one year.
