Organic Farming Systems and Nutrient Management

Organic Farming Systems Research

Funded by:
Integrated Organic Program, USDA CSREES
WSU Center for Sustaining Agriculture and Natural Resources
Western Region SARE

 

In 2002 we began an integrated research program focused on sustainable and organic production systems for small-scale, direct-market vegetable crop production. Our goal is to work with farmers to develop management systems that utilize local inputs to produce high-quality, high-value crops efficiently and profitably in an environmentally sustainable manner. 

 

Our research is focused in four areas:

  1. Using local sources of organic nutrients
  2. Cover crops
  3. Organic farming systems for vegetable crop production
  4. Soil quality
