CORVALLIS - The Oregon State University Extension Service has just published a new 50-page booklet for Oregon growers entitled "Using Cover Crops in Oregon."
The publication is intended to help make cover cropping management decisions, according to Richard Dick, professor of soil science at OSU and project leader for the publication.
"It is based on input from farmers and a wide range of OSU faculty, making it particularly applicable to conditions in the Pacific Northwest," Dick said.
Usually not grown for harvest, cover crops are planted to enrich soils with organic matter, cycle nutrients, protect soil from water and wind erosion, suppress weeds, insect pests and diseases and reduce nitrate leaching to groundwater, explained Dick.
Topics covered in the new booklet include: the benefits of cover cropping, possible disadvantages of cover cropping, how to choose a cover crop, cover crops in annual and perennial systems, how to estimate nitrogen contributions to a subsequent crop and economic considerations of cover cropping.
The booklet provides detailed information on specific cover crops suitable for Oregon including: annual ryegrass, barley, oats, triticale, wheat, buckwheat, cereal rye, common vetch, crimson clover, fava bean, field pea, hairy vetch, rapeseed, red clover, subterranean clovers, Sudangrass and sorghum-Sudangrass hybrids.
