This webinar highlights recent research by Rita Hummel of WSU on struvite as a phosphorus source for greenhouse production of bedding plants and vegetable starts. Her research includes struvite derived from municipal wastewater and dairy manure. Craig Cogger opened the webinar with a brief overview of the phosphorus challenge. After Rita’s presentation of greenhouse research results, Keith Bowers discussed struvite production as one phosphorus removal technology for wastewater at livestock, food processing, and public sewage treatment sites. The webinar closed with a brief summary by Craig and an open question period.
WSU scientist Lynne Carpenter-Boggs is working with an international group of scientists to help find bean varieties and microbial inoculates that will improve yields on the ancient soils that farms in many parts of Africa must contend with. Dr. Carpenter-Boggs took a Flip camera to Africa and shot some wonderful footage of farms, people and animals.
WSU scientists have conducted extensive research on Anaerobic Digestion (AD) as a technology for recovery of methane (energy), stable carbon, and nutrients from organic wastes such as manure, food processing wastes and the organic fraction of municipal solid wastes (OFMSW). Our research has evaluated the technical and economic performance of commercially available systems, developed improved AD reactors, and commercialized WSU patented nutrient recovery technology. This webinar, presented by CSANR director Chad Kruger and CSANR scientist Craig Frear, will provide an update on the latest results from the WSU Climate Friendly Farming Project’s AD research.

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.
Beginning in 2002, organic amendments, cover crops, and soil quality have been investigated in our farming systems experiment. An interdisciplinary team is studying a range of issues important to smale scale, direct-market, and organic agriculture, including nutrient management, soil quality, weed management, economics, marketing, and on-farm research.
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.
