Coated bioactive granular material subjected to anti-floating treatment and method for producing the same

摘要

PROBLEM TO BE SOLVED: To provide a coated bioactive granule that hardly floats on a water surface when used in water, and a method for manufacturing the same. SOLUTION: A coated bioactive granule, represented by coated fertilizer or coated pesticide, is subjected to a floating preventive treatment where the granule is again coated with a soil pelletizing agent or a resin having =1,000 mg/g of acid value/hydroxyl value. The above treated granule is furthermore subjected to another floating preventive treatment where water-soluble inorganic powder is adhered onto the surface of the granule. The method for manufacturing these granules is disclosed.
