This Crop File contains basic information about various products that claim to enhance the agronomic efficiency of applied nitrogen. It is not intended to be a comprehensive list, but includes many products that are currently being marketed (as of April 2019). These products can vary greatly in their agronomic effectiveness and not all products perform as promised. More information can be found in Crop File 2.04.002, Nitrogen Fertilizer Additives and Extenders.
