Method of producing organic-mineral fertilizer of the digestate involving concentrating of digestates with flocculants of mineral origin, extrusion, homogenization and mixing with lime is characterized in that the digestate containing 3 - 9% dry matter is concentrated to 25 - 30% dry matter by using flocculants of mineral origin is subjected to extrusion, followed by the stirring, simultaneously injecting the mixture of quicklime and ashes from biomass with ratio 2 - 5:1 in an amount of 0,1 - 0,5 kg per 1 kg of concentrated substrate, after which the obtained mass is subjected to cooling and granulation by known methods, wherein used ashes from the biomass used in the process of the fertilizer production are derived from forest and/or agricultural biomass, and quicklime used during the process has reactivity not more than 1,5 minutes. |
