METHOD FOR MANUFACTURING BIOHUMUS Russian patent published in 2003 - IPC

FIELD: agriculture, production of fertilizers. SUBSTANCE: poultry dung should be supplemented with organic loosening agents as wood saw-dust, cuttings and shavings followed by mixing and moisturizing up to 80- 90%. The obtained substrate is placed as storage piles at open areas and subjected to biothermal composting. Composting process is carried out at maximum temperature of 70 C by decreasing it up to minimal value of 25-30 C at the end of the process at constant loosening to enrich inferior layers with oxygen and remove gas. Ready-to-use substrate is put into trenches to occupy with red California worm of Esenia foetida type by putting it by bundles along the whole substrate's surface. Trenches should be covered with film. After processing all substrate's thickness to obtain biohumus and film removal one should remove upper dried layer and separation of the rest biohumus against worms with the help of traps as nettings. The rest ready-to-use biohumus should be sieved and dried up to 65% moisture value. The present innovation enables to obtain organic fertilizer out of poultry factories waste products. EFFECT: higher efficiency of manufacturing.
