The overuse of nitrogen fertilizers in agriculture can wreak havoc on waterways, health and the environment. An international team of scientists aims to lessen the reliance on these fertilizers by helping beans and similar plants boost their nitrogen production, even in areas with traditionally poor soil quality. Researchers from the Center of Plant Genomics and Biotechnology at the Technical University of Madrid (UPM) and the Advanced Photon Source (APS) at the U.S. Department of...

A 125-year debate on how nitrogen-fixing bacteria are able to breach the cell walls of legumes has been settled A 125-year debate on how nitrogen-fixing bacteria are able to breach the cell walls of legumes has been settled. A paper to be published on Monday by John Innes Centre scientists reports that plants themselves allow bacteria in. Once inside the right cells, these bacteria take nitrogen from the air and supply it to legumes in a form they can use, ammonia. Whether the bacteria...

Nitrogen is vital for all plant life, but increasingly the planet is paying a heavy price for the escalating use of nitrogen fertilizer. Excess nitrogen from fertilizer runoff into rivers and lakes causes algal blooms that create oxygen-depleted dead zones, such as the 6,000 to 7,000 square mile zone in the Gulf of Mexico, and nitrogen in the form of nitrous oxide is a potent greenhouse gas. But new findings by Stanford researchers that reveal the inner workings of nitrogen-producing bacteria...

U.S. entomologists say a careful choice of nitrogen-fixing bacteria might provide soybean farmers protection against an invasion of soybean aphids. Pennsylvania State University researchers said soybeans are legumes -- plants that can have a symbiotic relationship with nitrogen-fixing bacteria called rhizobia and therefore do not need additional nitrogen fertilizer. Each type of legume -- peas, beans, lentils, alfalfa -- have their own rhizobia. Soybeans are from Asia and so there were...
