METHOD OF POWDER FERTILIZER UTILIZING AMINO ACID

摘要

The fertilizer is made by; (a) adding 3.5-5% rock phosphate and 1.5-2.5% zeolite to solution, concentrated from remains after amino acid (L-glutamic acid or L-lysine) fermantation until its specific gravity becomes 1.3-1.5; (b) aging for 4-6 hrs with the temperature dropped from 45 deg.C to 30 deg.C; (c) dehydrating and drying. The fetilizer is easy to manufacture and store because of being not viscous.
