This WSU Small Farms Team website provides links to various resources on compost science, operations and equipment, compost tea, and vermicomposting.
WSU operates a full scale composting facility on the Pullman campus to recycle organic waste, while providing teaching and research opportunities.
The WSU Puyallup Research Center faculty have conducted extensive work on compost, manure and biosolids. This website provides information on yard waste and food waste composts, clopyralid, calculating bulk density, nutrient management for organic systems and compost facility operator training events. The site has links to the Compost Mix Calculator the Organic Fertilizer Calculator and Center research publications.
An archive of digital photos of various aspects of agricultural composting and compost use to assist agricultural professionals and others in their education programs. Produced as part of the Compost Education and Resources for Western Agriculture project with funding from the Western SARE Program.

Recorded webinar (online presentation) from Jan 2011 by Craig Cogger, Crop and Soils Scientist and Extension Educator. This seminar discusses research and guidelines on soil amendment choices based on use, nitrogen availability, carbon sequestration potential, handling nutrient imbalances in organic amendments, and an update on herbicide issues in some composts.

This national initiative seeks to renew what is being called the “agriculture-of-the-middle.” This term refers to a disappearing sector of mid-scale farms/ranches and related agrifood enterprises that are unable to successfully market bulk commodities or sell food directly to consumers. Begun as a task force in 2003, the initiative is entering a development phase.

Choosing mustard varieties and on-farm research results on variety biomass measurements and glucosinolate concentrations and production.
On-farm research has been conducted since 1999 to determine the benefits of mustard green manures and to improve their effectiveness. They are being used in irrigated regions of Eastern Washington to improve soil quality, control wind erosion, and manage soilborne pests.
Since 1985 the U.S. government has implemented the Conservation Reserve Program (CRP) which pays farmers NOT to grow crops on millions of acres of highly erodable land. In addition to being a controversial program, much of this land is now coming out of CRP which puts pressure on farmers to grow crops in these areas once again. In the Palouse in Washington State, local farmers and ranchers are looking at holistically grazing livestock as an economically and environmentally sustainable alternative to traditional wheat farming in these sensitive areas and to the CRP in general.
