Abstract

1334188 Coated fertilizers SHOWA DENKO KK 10 Nov 1971 52263/71 Heading C1B A coated fertilizer, having controlled release of ingredients in use, is manufactured by coating fertilizer pieces or particles with a preparation comprising a water-soluble resol-type phenol resin having a water tolerance of one or greater, an organic acid having a dissociation constant not exceeding 2 x 10<SP>-4</SP> and filler in less than 30 parts per 10 parts resin, and heating to a temperature between 100‹ and 130‹ C. The organic acid may be formic, acetic or butyric acid, and the filler may be talc, silica, white carbon or wheat flour. In examples, high analysis NPK fertilizer containing ammonium sulphate, ammonium phosphate and potassium chloride is used.
