Abstract:: Fava bean is used as a winter or spring cover crop, green manure, silage, forage, hay, and vegetable. It is capable of producing large amounts of dry matter and accumulating large quantities of nitrogen (N), part of which is available to subsequent crops.

Creator:: Oregon State University. Extension Service and Smiley, Richard W.
Abstract:: Nematodes are roundworms with complex organ systems. They occur worldwide in all environments. Most species benefit agriculture by contributing to decomposition of organic matter and are important members of the food chain. Some species are parasitic to plants or animals. More than 2,000 of the 20,000 identified nematode species are...

Creator:: Ingham, Russ, Dick, Richard, Sattell, Robert, and Oregon State University. Extension Service
Abstract:: Traditionally, M. chitwoodi is controlled with chemical nematicides, many of which risk suspension for use on potatoes due to health and environmental concerns. It is essential to develop and refine alternative strategies for controlling Columbia root-knot nematode now, so that productive and profitable potato acreage will not be lost if...

Creator:: Sattell, Robert, Buford, Thomas, Murray, Helene, Dick, Richard, McGrath, Daniel M. (Daniel Morton), and Oregon State University. Extension Service
Abstract:: Cover crop selection and management depend on many factors, among them the cover crop’s ability to accumulate dry matter (i.e., residues) and nitrogen (N). Dry matter provides energy for soil organisms, contributes to soil organic matter, improves tilth, and acts as a sink for nutrients.

Abstract:: Buckwheat is not likely to increase soil organic matter content much because dry matter production is relatively low and tissues are succulent and decompose very rapidly when incorporated. However, buckwheat can improve short-term soil tilth and has been used to prepare fields for transplants.

Creator:: Sattell, Robert, Dick, Richard, Hemphill, Delbert D., McGrath, Daniel M. (Daniel Morton), and Oregon State University. Extension Service
Abstract:: Subclovers are used for forage and hay and have been used successfully in Oregon as fall-planted and relay interplanted cover crops in annual rotations. They are capable of accumulating substantial amounts of N, a portion of which is available to the following crop. Rapid growth suppresses weeds in spring.

Abstract:: Sudangrass and sorghum sudangrass crosses are used as warm season cover crops, forage, and silage. When used as a cover crop, their fibrous roots and organic matter contributions improve soil structure; and their rapid, dense growth suppresses weeds.
