Animal Manure Management May 13, 2014 Print Friendly and PDF

The Science Symposium was focused on the principals and science supporting dairy nutrient management planning in Washington State. Speakers were from UC Davis, Agriculture and Agri-Food Canada-British Columbia, Oregon State University, Washington State University, WA Department of Ecology, Sunnyside Irrigation District and Whatcom Conservation District. Presentations related to WA NRCS Tech Note 14 (Winter Spreading) and the WA NRCS 590 (Nutrient Management Standard). The symposium ended with a panel discussion with the speakers, and concluded with a summary of expected next steps.

The goals of the symposium were to:

1. Learn the latest research regarding the winter spreading of dairy manure on water quality.

2. Identify areas of scientific agreement

3. Develop next steps
