Hedgerows, also known as shelterbelts or windbreaks, are rows of trees, shrubs, and low-growing plants that divide or border fields and/or suburban lots. In England, many farms are surrounded by ancient hedgerows that conserve soil and water, provide a home to wildlife, and serve as barriers. In the United States,...
Many buyers of processed vegetables are responding to consumer concerns by demanding that producers have an effective environmental stewardship program and reduce pesticide use. Snap bean producers have an opportunity to meet
these demands. The snap bean and 12 spot beetle interaction is relatively simple. Methods for determining risk of...

Cancellation of the registration of an effective bean mold fungicide, Ronilan, is slated to occur at the end of growing season in 2005.

Agricultural scientists recognize farmer knowledge and experience can provide important contributions to the development of new agricultural technologies. However, insufficient use has been made of this valuable resource because farmer knowledge and experience are difficult to collect, quantify, and evaluate.
Discusses ways to apply integrated pest management principles to management of 12-spot beetles (Western spotted cucumber beetle) in snap beans. Covers pest description, crop damage, biology and life history, scouting and thresholds, and sweep net sampling. Presents information in English and Spanish.
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.
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.
Rapeseed is grown for its oil and meal, and as a cover crop. Rapid fall growth captures part of the available soil nitrogen, which otherwise might be lost to leaching, and provides good ground cover over winter.
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.
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.
Common vetch is a viny, succulent, annual legume attaining a height of 24 inches when planted alone. It grows taller when planted with a tall companion crop that provides structural support for climbing.
Crimson clover may be used as a cover crop, green manure, pasture, or hay. It often is used as a winter annual cover crop in annual rotations. It has been used successfully in reduced-tillage farming systems, and in orchards and vineyards where it can be managed to reseed itself.
Hairy vetch is used as a cover crop, green manure, pasture, silage, and hay. It is capable of accumulating large amounts of dry matter and nitrogen. When planted alone as a winter cover crop in annual vegetable rotations, it can provide substantial amounts of nitrogen (N) to a following crop.
Field pea can be used as a cover crop, green manure, forage, hay, and silage. Hay is good quality, but pea is more succulent than vetches and more difficult to cure. Regrowth after mowing or grazing is poor.

Cereal grains are grasses and may have a prostrate, semierect, or erect physical stature. All have fibrous root systems.
Barley, oats, triticale, and wheat are each comprised of hundreds of varieties whose growth characteristics vary considerably.
Cereal rye is an erect annual grass with greenish blue, flat blades and an extensive fibrous root system. It resembles wheat, but usually is taller (3–5 ft) and tillers less. Flowering is induced by 14 hours of light in spring.
Agricultural land management, such as fertilization, liming, and tillage affects soil properties, including pH, organic matter content, nitrification rates, and the microbial community. Three different study sites were used to identify microorganisms that correlate with agricultural land use and to determine which factors regulate the relative abundance of the microbial...

Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous in the environment as components of fossil fuels and by-products of combustion. Defining toxicity mechanisms for this large family of multi-ring structures and substituted derivatives is a substantial challenge.
