TECHNOLOGY FOR OBTAINING ORGANOMINERAL FERTILIZER FROM THE STRAW OF CEREALS

Abstract

This article discusses the role of cereal waste from sown areas to obtain organic mineral biological fertilizers from straw of cereal crops in crop production. The introduction of straw increases the content of humus, improves the structure of the soil, reduces its tendency to erosion, and stimulates the process of nitrogen fixation. It is a food source for soil microorganisms, without which the availability of individual nutrients would be limited. Water and air regimes and soil absorption also improve. The method for the production of fertilizers from straw, proposed in the article, includes processing the feedstock by grinding it with simultaneous heat and pressure, further filtering the feedstock with water and carrying out the process in a nitric acid reactor, then the product is sent to an acid neutralizer. Thanks to the proposed method, we obtain a combined fertilizer containing, in addition to nitrogen in the ammonium form, i.e. the most valuable form in terms of nitrogen fertilizers, is also another component, potassium, which is important too.
