Crop sensors outdo farmers at choosing nitrogen rates

Choosing how much nitrogen (N) to put on corn fields isn't something farmers take lightly. Many factors go into the decision, including past experiences, the timing of application, yield goals, and results from soil tests.

Comparing soybean production methods

In the Mid-South, twin-row soybean production is becoming a popular growing technique for soybean producers. An estimated 80% of the total hectares grown in the Mississippi Delta are planted in this configuration. While growers ...

The future of cover crops

Winter cover crops are an important component of nutrient cycling, soil cover and organic matter content. Although its benefits are well documented, cover crop use in farming systems is relatively low. Research has shown ...

Dairy farmer finds unusual forage grass

A U.S. Department of Agriculture (USDA) grass breeder has rediscovered a forage grass that seems just right for today's intensive rotational grazing.

Iron deficiency in soil threatens soybean production

An expansion of soybean production into areas where soybean has seldom, if ever, been grown can be problematic for some farmers. Soils having high pH values and large amounts of calcium and/or magnesium carbonate are notoriously ...

Finding the right time for rolling rye

(PhysOrg.com) -- U.S. Department of Agriculture (USDA) scientists are helping growers adopt an environmentally friendly practice that is catching on nationwide: "rolling" their rye when they use it as a cover crop.

Early cotton planting requires irrigation

Cotton growers can produce more cotton if they plant early, but not without irrigation. That's the finding of an article published in the September-October 2010 Agronomy Journal, a publication of the American Society of Agronomy.

Yield projections for switchgrass as a biofuel crop

While scientists have conducted numerous studies on production of biomass from biofuel crops, such as switchgrass, no one has yet compiled this information to evaluate the response of biomass yield to soils, climate, and ...
