How do we solve the problem of agricultural nutrient runoff?

Agricultural runoff from Midwestern farms is a major contributor to a vast "dead zone" in the Gulf of Mexico. Nitrogen, phosphorous and other farm nutrients drain into the Mississippi River, which empties into the Gulf, spurring ...

Turned-down temperatures boost crops' penchant for production

Drought and heat put stress on plants and reduce grain yield. For some farmers, irrigation is the answer. Many of us assume the practice boosts crop yields by delivering soil water, but it turns out irrigation's cooling effect ...

Researchers quantify ecosystem-scale nitrification rate

Human-caused increases in gaseous nitrogen (N) emissions to the atmosphere have accelerated terrestrial ecosystem N deposition over the past half-century. As forest productivity is usually N limited, accelerated N deposition ...
