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 ...
Most living plant and animal species have a certain, relatively small, amount of variation in their genetic make-up.
(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.
E. coli can live for weeks around the roots of produce plants and transfer to the edible portions, but the threat can be minimized if growers don't harvest too soon, a Purdue University study shows.
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.
By planting switchgrass and using certain agronomic practices, farmers can significantly reduce the amount of nitrogen and nitrates that leach into the soil, according to Iowa State University research.
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 ...
No significant differences in corn yield were found between organic and chemical sources of nutrients, but a Texas AgriLife Research economist said manure generates higher economic returns than anhydrous ammonia.
A one-time tillage has no adverse effects on yield or soil properties on no-till land, according to field research conducted at the University of Nebraska-Lincoln. Although tillage is another expense for farmers and generally ...
Despite sophisticated nutrient management of potato crops, quality and yield still see wide variability. Although nutrients are already well understood, the influence of other environmental factors remains understudied.
