Organic Agriculture 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.

Advances in Brassica seed meal formulation and application protocol for control of apple replant disease.
M. Mazzola poster, December 2010, Wash. St. Hort. Assoc. meeting. A summary of the most recent field results using brassica seed meal mixtures.
The objective of this paper is to provide an Input-Output (IO) based economic impact analysis for organic apple production in Washington State.
The Plant Breeding program at NWREC concentrates on crops that fit into diverse annual and perennial rotations on small and mid-sized farms. Farmer participatory approaches and other innovative methods are utilized to improve crops such as small grains. Research is prioritized to favor producer groups and crops that are not being served by conventional research programs and approaches.

Dr. Carol Miles, WSU Mt Vernon Research and Extension Center, and Dr. Pete Bristow, WSU Puyalllup, are investigating organic options to control root rot (Phytopthora fragriae var. rubi). This study is focused on organic root rot control, however all raspberry growers will benefit from new disease management options.
In 2003 an organic vegetable production systems experiment was established on organically certified research land at WSU Puyallup. The experiment compares 12 organic management systems, including three cover cropping systems, 2 tillage treatments, and 2 amendment types, arranged in a split-split plot design.
Trials examined weed control, soil quality, tree nutrition, and water use. Also monitored for voles, and testing potential for mulch to host nematodes for control of codling moth larvae. David Granatstein, WSU CSANR, Wenatchee.

Agriculture can be both a source and a sink for greenhouse gases. In this webinar, the presenters discuss these roles of agriculture, how management affects them, and ways in which organic farming systems in particular may influence greenhouse gases.
