    (54) METHOD OF OBTAINING ORGANIC FERTILIZER
    This invention relates to agriculture. A known method of producing fertilizers, comprising mixing bird droppings with water tl. A known method of producing organic fertilizer, including processing animal extracts with mineral acids with a humidity of 80-85% in an amount of 0.6-0.7% at a temperature of 125130 ° C for 2 , 5-3 h, followed by neutralization of the hydrolyzate to pH 5.0-5.5 and separation into solid and liquid phases 2. However, with such methods, fertilizers are obtained with a low content of organic nitrogen-containing compounds. The purpose of the invention is to obtain a liquid fertilizer with a high content of organic nitrogen-containing compounds. This is achieved by the fact that animal secretions are mixed with water, treated with mineral acids to a pH of 0.1-2.0, kept for 2-12 hours at normal temperature and pressure, then decomposed for 24-60 hours, the resulting liquid phase is separated from undissolved solids, the pH is adjusted to 5.0-6.2 by adding the basic substance, and after neutralization is completed, the precipitated precipitate is separated, and to obtain the initial aqueous phase, equal amounts of water and solid excreta are taken; benefits For example, chicken / bird droppings are taken in mixture with solid and / or liquid excreta of other animals, animal excretions are mixed with water for 5-6 hours, and before exposure to mineral acids, coarse foreign bodies are separated, and the resulting gases are mixed with water. by introducing air into said mixture; oxide, hydroxide or carbonate carbonate are taken as the basic substance, after the basic substance is added, the precipitate is separated by centrifugation, the initial solids content of the aqueous phase is chosen such that the solids content in the final product is 4.0 wt%. Example. Prepare a watery mixture of animal excreta. The mixture contains about 70-80 wt.% Water, and
