New book rethinks the relationship between sulfur and crops

MADISON, WI, October 1, 2008 - As a nutrient, sulfur is often overlooked in favor of nitrogen, phosphorus and potassium, but a new book explains its crucial role in soil condition, plant growth and nutrition. For agricultural professionals, understanding how plants use sulfur is essential for opti...

Shade trees can protect coffee crops

Sustainable farming that employs shade trees may improve crops' resistance to temperature and precipitation extremes that climate changes are expected to trigger, according to an article published in the October issue of BioScience . The article, by Brenda B. Lin, Ivette Perfecto, and John Vander...

MSU to create genomic clearinghouse for biofuel crops

EAST LANSING, Mich. Michigan State University scientists, armed with a half-million-dollar federal grant, are creating an easily accessible, Web-based genomic database of information on crops that can be used to make ethanol. "Ultimately this will allow us to create better biofuel crops," said...

Rising energy, food prices major threats to wetlands as farmers eye new areas for crops
