FIELD: agriculture.
SUBSTANCE: the present innovation deals with preparing fertilizers out of organic wastes of animal science, poultry science and vegetable growing. One should divide organic waste products into liquid and solid fractions, supply air into the mass of organic wastes followed by fermentation. Division into liquid and solid fractions should be carried out under the shed at an even platform supplied with sewages for liquid fraction and canals to supply air from below into the mass of organic wastes. Solid fraction should be periodically thrown over without thickening, and liquid fraction undergoes anaerobic fermentation. The innovation in question enables to increase the quality of fertilizer and decrease financial and exploitation expenses at manufacturing fertilizers.
EFFECT: higher efficiency of manufacturing.
