FIELD: fertilizers.
SUBSTANCE: method of producing nitrogen fertilizer and soil improver from liquid manure and/or manure includes the following stages: separating liquid manure and/or manure into a solid fraction and a liquid fraction, subjecting the liquid fraction to ammonia distillation, resulting in a liquid fraction with a low nitrogen content and a gas phase containing ammonia, extracting nitrogen from the gas phase into a liquid solution containing acid, resulting in a solution of ammonium salt (ammonium nitrogen), treating the solid fraction by pyrolysis, in which charcoal, pyrolysis liquid and pyrolysis gas are formed, loading an ammonium salt solution, obtained from the nitrogen extraction stage, into charcoal formed through the pyrolysis process, which produces nitrogen fertilizer and soil improver as the final product.
EFFECT: provision of the possibility of obtaining a new type of fertilizer from fresh manure without the fermentation process, and this fertilizer simultaneously acts as a nitrogen fertilizer and as a soil improver due to the charcoal content.
