Since intensive agriculture negatively affects the fertility of cultivated land, the article raises the relevance of the issue of switching to organic agriculture. Moreover, with the continuous growth of production and consumption waste, there is a need to understand its potential value and reusability. One such technique is the production of organomineral fertilizers in the form of composts. We have previously proposed a favorable ratio of waste in the composition of compost. It included semi-dried manure cattle, phosphogypsum and alfalfa straw. This article presents the results of field studies assessing the effect of different doses of the test compost on the ecological properties of the chernozem leached in growing corn on grain. Positive dynamics were revealed for the following indicators: concentration of organic substance, mobile phosphorus, total and ammonium nitrogen.
