MICROBIAL ORGANIC FERTILIZERS AND METHODS FOR PRODUCING THEM

摘要

1. A method of obtaining a liquid bioorganic fertilizer, including aqueous extraction of mineral nutrients and biologically active substances contained in the feedstock, and the subsequent separation of water-insoluble sediment, alkaline extraction of humic substances from it, separation of the alkaline extract, its neutralization and compounding with the obtained aqueous extract, characterized in that: the compounds should be only of organic origin, water extraction is carried out for 1-3 hours at 20-40 ° C, the ratio of raw materials to ext Gent is 1: 3-1: 5; alkaline extraction is carried out for 10-16 hours at 20-40 ° C, then the alkaline extract is neutralized with citric acid to pH 6.5-7.5; and then combined with the aqueous extract, stirred and allowed to stand, and the result is the desired reaction product. 2. The method according to claim 1, characterized in that the bioorganic fertilizers containing humus used as feedstock contain, in addition to a complex of mineral nutrients and biologically active substances, effective microorganisms. A method according to claim 1, characterized in that the extract obtained as a result of water extraction contains live effective microorganisms. The method according to claim 1, characterized in that the alkaline extraction is carried out twice using a 3.0-8.0% aqueous solution of vegetable ash as an extractant, the ratio of water-insoluble sediment and alkaline extractant is 1: 5-1: 10.5. The method according to claim 1, characterized in that 10-15 mg / l of sorbic acid is added to the neutralized alkaline extract.
