Accomplishments

By Objective

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.

Peer-reviewed book chapters, journal, and extension articles were published by members of the group with 100s of presentations at various professional and grower meetings. Additionally, a range of online material and user-friendly calculators have been developed. These examples 

Objective #2: Promote effective use of soil, water, plant, manure and compost analytical information.

Expansion of the multi-state Agricultural Laboratory Proficiency Program and the growing Manure and Compost Analysis Proficiency programs (Robert Miller, CSU)

North American Proficiency Testing (NAPT) Program (with the Soil Science Society of America) continues to be coordinated, supported and utilized by members of WERA-103 with Bryan Hopkins as the program lead.

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

WERA-103 members have provided many presentations and talks for both agriculture producers, industry personnel, and other researchers. Below are some examples of their outreach.

Articles were published in Crop and Soil Magazine with a circulation of ~15,000
