METHOD OF PREPARING LIQUID BIOLOGICAL PLANT GROWTH STIMULATOR FROM HUMUS-CONTAINING SUBSTANCES Russian patent published in 1998 - IPC

Abstract RU 2112763 C1

FIELD: plant growth stimulators. SUBSTANCE: humus-containing substances are submitted to alkaline extraction followed by neutralizing extract. According to invention, initial substances are composts preliminarily prepared from manure waste from stock-raising farms. Composts are additionally treated to separate aqueous bacterial suspension from solid compost fraction. Solid fraction is extracted by 0.1-1.0 N alkali solution at 20 to 50 C, whereupon separated liquid extract is combined with bacterial suspension and mixture is settled down to yield desired liquid product. EFFECT: improved quality, increased yield of product, and improved economical efficiency of process. 20 cl, 5 tbl
