Labile soil organic matter promotes better corn performance
Washington DC (SPX) Feb 14, 2013
Organic matter is important for soil health and crop productivity. While an indicator of soil quality, a lot of organic matter is in extremely stable forms, and the nutrients in such forms are difficult for plants to use. The active, labile fraction, however, is a modest but important part of the organic matter. "The labile fraction is small - usually less than 20 or even 10 percent, depending on how you define it," explains Steve Culman, lead author of a study published online Feb. 8 in Agronomy ... read more
