Method of producing organic fertiliser Invention relates to agriculture. The method producing organic fertiliser involves fermentation of a raw product, removing biogas, separation, wherein the raw product used is in form of bird or animal excrement which undergoes preliminary fermentation; after fermentation and removal of biogas, the dense component of the raw product is separated from the fermentation product and the liquid component is mixed with a flocculant; the flocculation product is settled until achieving separation of the solid fraction and the liquid fraction in a ratio from 1:3 to 1:5; the liquid fraction is removed and the remaining product is decanted to moisture content of 40-50%; the liquid component is removed and the decanted mass is mixed with the dense component of the separation product and pressed with an auger device or is first pressed with an auger device and then mixed with the dense component of the separation product that has been pressed with an auger device, wherein at the outlet of the auger device, the product has moisture content of 20-30%, after which the product is heat dried at temperature of 40-60°C to moisture content of 10-15%. |

Method of production of organic fertiliser and feed additives based on residual products of processing of fish scraps, in which a mixture of any fish scraps is crushed and milled to fractions with the diameter no more than 2-3 mm, the preparatory process is performed, comprising uniform mixing, thermal heating for not more than 5 hours at a temperature of 80°-90°C, cooling to a temperature not lower than 45°C, maintenance of humidity of the mixture not lower than 75%, then the process of anaerobic fermentation in the reactor at an optimal temperature of 60°C is carried out. At that in the fermentation process once the temperature jump to 105°C for 15-20 min is provided, the phosphoric acid solution and the enzymes of biological nature are added, the final product after the fermentation is subjected to separation of the liquid component and the biological sludge (centrifuge effluent), a mixture of low molecular weight fatty acids is added to the final paste granulate. |
