More care should be taken, particularly with sensitive seeds such as beans or peas, and on coarse-textured soil (sand and sandy loam), than is required with ammonium nitrate or monoammonium phosphate. It lowers the combustion temperature of the material, decreases maximum weight loss rates, and causes an increase in the production of residue or char.
