Abstract: At present, the problem of fertility, use, conservation and restoration of soils is acute. The results of the study of the effect of percentagefertilizer systems on the productivity of crops of crop rotation for 2011-2017 are considered. We studied changes in the properties of chernozems on the territory of the Southern Urals with grain-steaming crop rotation without the use of fertilizers in versions using mineral organic and organic-mineral fertilizers. The results of the study of the content, stock, balance of fertilizer elements for agricultural use are shown. It has been established that the cultivation of crops without the use of fertilizers is accompanied by a slight increase in acidity, a decrease in the degree of saturation with bases and the process of dehumification, the use of mineral fertilizers provoked a clear increase in acidity. The introduction of organic fertilizers somewhat inhibits these processes. The results of a study of the influence of local ameliorants on yields of crops and agrochemical properties of soil are presented. It was established that waste from JSC "Soda" soda production and organo-mineral fertilizers on the basis of brown coal from the Kumertau deposit increased crop yields without worsening the agrochemical indices of the soil. And on the contrary, reducing the exchange acidity, enriching the content of the amount of phosphates, water-soluble and exchangeable potassium.
