摘要

PROBLEM TO BE SOLVED: To provide a granular ammonium nitrate based fertilizer and a coated granular ammonium nitrate based fertilizer having ammonium nitrate as a main component and free from the fear of being mixed with an organic material and having excellent preservation stability in outdoor storage. SOLUTION: The granular ammonium nitrate fertilizer having flame retardancy and preservation stability contains 0.5-5 wt.% potassium component expressed in terms of K2O as a stabilizer, 2-5 wt.% phosphate component expressed in terms of P2O5as a flame retardant and 70-85 wt.% ammonium nitrate. The coated granular ammonium nitrate fertilizer is obtained by coating the granular ammonium nitrate fertilizer with a resin-containing coating film. COPYRIGHT: (C)2005,JPO&NCIPI
