METHOD FOR PRODUCTION OF BIOHUMUS Russian patent published in 1995 - IPC

FIELD: production of organic fertilizers. SUBSTANCE: method is based on bringing technology as close as possible to natural process of humification of organic waste. However, these natural conditions are optimized so as to minimize the time spent for transformation of waste. In the claimed method the biothermal process is conducted in semicircular piles with a radius of 1.1 1.2 m and the base equal to pile diameter; the feedstock for the preparation of organic substrate is mixed in advance with the ready organic substrate ("starter") in a weight ratio of 20-10:1. The vermicompost is granulated at a moisture content of 40-45 wt.-% and the granules are held to a complete humification at free air exchange throughout their volume. EFFECT: higher quality of biohumus, reduced time and expenses for its production. 5 cl, 6 tbl
