NOVELTY - Method for obtaining a liquid bioorganic fertilizer, involves performing aqueous extraction of mineral nutrients and biologically active substances contained in starting raw material and separating water insoluble deposit, alkaline extraction of humus substances, alkaline extract, neutralizing and combining with the obtained aqueous extract, where aqueous extraction is performed at 20-40 degrees C for 1-3 hours and alkaline extraction is performed at 20-40 degrees C for 10-16 hours, and stirring and allowing the mixture to stand to obtain target reaction product.    USE - The method is useful for obtaining liquid bioorganic fertilizer used for organic farming in agriculture, forestry, growing ornamental plants, and for industrial treatment of poultry and animal breeding waste.    ADVANTAGE - The method produces environmentally-friendly bioorganic fertilizers, consumes less energy, is simple with less number of production stages, rapidly performs microbial fermentation in anaerobic conditions, and ensures safe disposal of corrosive droppings from poultry farms. The produced fertilizer provides high yields, avoids intensive use of mineral fertilizers, thus prevents significant mineralization of soil and loss of fertility, is cost-effective, contains effective microorganisms balanced according to generic composition, does not contain undesired foreign bacterial microflora, avoids seasonal restrictions on the use of prototype fertilizer depending on domination of anaerobic cellulose-degrading microorganisms, has excellent quality, high humidity, viscosity, heterogeneity, high content of mineral nutrients and biologically active substances, high agrochemical rates, does not have rotten smell, increases fertility and quality of products at reduced dosage, and does not require special equipment and security measures for implementation of high-temperature alkaline extraction.    DETAILED DESCRIPTION - Method for obtaining a liquid bioorganic fertilizer, involves performing aqueous extraction of mineral nutrients and biologically active substances contained in starting raw material and separating water insoluble deposit, alkaline extraction of humus substances, alkaline extract, neutralizing and combining with the obtained aqueous extract, where the compounds must be of organic origin only, aqueous extraction is performed at 20-40 degrees C for 1-3 hours, the starting raw material to extractant ratio is 1:3-1:5, alkaline extraction is performed at 20-40 degrees C for 10-16 hours and alkaline extract is neutralized with citric acid to 6.5-7.5 pH level, and stirring and allowing the mixture to stand to obtain target reaction product.
