ABSTRACT
The article presents information on a new model to gauge ammonia nitrogen losses, developed by Clemson University of Clemson, South Carolina, which could change the way farmers think about nutrients and application methods in conservation-tillage in the Southeast. Clemson University Extension Ag Engineer John Chastain and colleagues found that the current Clemson University estimates of ammonia-N loss differ from the new model by 2 percent to 95 percent. In developing the new method to estimate ammonia-N losses, the researchers used literature and new data obtained at Clemson to develop the model that considers the organic nitrogen available to the plant, and loss of ammonia-N following application in a conservation-tillage system.
