GPS helps locate soil erosion pathways

Grassed waterways are placed in agricultural fields where runoff water tends to concentrate because they can substantially reduce soil erosion. Mapping techniques that help identify where erosion channels will likely form ...

Understanding the historical probability of drought

Droughts can severely limit crop growth, causing yearly losses of around $8 billion in the United States. But it may be possible to minimize those losses if farmers can synchronize the growth of crops with periods of time ...

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 ...

Straw residue helps keep nitrogen on the farm

Scientists are exploring ways to reduce non-point pollution from agriculture. A new study finds that using straw residue in conjunction with legume cover crops reduces leaching of nitrogen into waterways, but may lower economic ...

Reducing fossil energy use on the farm

Conventional agriculture production relies heavily on fossil fuels, particularly in its ability to provide energy at a low cost. However, the uncertain future of fossil fuel availability and prices point to need to explore ...

Plant soybean early to increase yield

Over the past decade, two-thirds of Indiana growers have shifted to planting their soybean crop earlier because they believe that earlier planting increases yield. Planting date is probably one of the most important yet least ...
