POTASSIUM PHOSPHATE-MODIFIED, PROLONGED ACTION PEAT-ZEOLITE FERTILISER Russian patent published in 2013 - IPC C05D9/00 C05G1/00 

FIELD: chemistry.

SUBSTANCE: potassium phosphate-modified, prolonged action peat-zeolite fertiliser which contains lowland peat and natural zeolite modified with potassium phosphate K₃PO₄, in ratio of 2.7:1-3.2:2, wherein the natural zeolite, which is ground to grain size of 0.8-1.1 mm, is saturated with 0.4-0.6% potassium phosphate K₃PO₄ solution for 10-12 hours with ratio of the weight of the natural zeolite to the potassium phosphate solution of 1:8-1:12.

EFFECT: invention increases bioproductivity of low-fertility cryoarid and cryogenic soils and crop yield, improves qualitative composition thereof and speeds up ripening thereof.
