METHOD FOR OBTAINING ORGANOMINERAL FERTILIZER Russian patent published in 2004 - IPC

Abstract RU 2235707 C2

FIELD: agriculture.

SUBSTANCE: the present innovation deals with obtaining organomineral fertilizers for plant growing, especially in soils with low humus content. The method deals with treating brown coal due to chemical impact followed by its mixing with nutritive components. Brown coal should be treated at environmental temperature with 20-25%-ammonia water for 10-20 min at weight ratio of solid and liquid phases being 1: (0.019-0.025). Then coal treated with ammonia water should be successively mixed with phosphate fertilizer (PF) and carbamide (CA) at weight ratio PF : coal = (0.8-1.5) : 1, CA : coal = (0.3-1.0) : 1. The method enables to simplify procedure to obtain fertilizer, increase its productivity value and quality of fertilizer.

EFFECT: higher efficiency.
