EFFICACY OF N USE FROM FALL APPLIED AMMONIATED PHOSPHATES AND AMMONIUM SULFATE

Open publisher page 0 citations

Abstract

Fall application of a blend of phosphate and potassium fertilizers is a common practice in much of the Corn Belt. The primary sources of phosphate are diammonium phosphate (DAP) and monoammonium phosphate (MAP), two granular fertilizers that are highly water soluble. Ammoniated phosphate fertilizers are often used as they are usually the cheapest source of nitrogen in the marketplace. In addition, there is evidence that the presence of ammonium will result in increased uptake of phosphate.
