Summary:Studies were carried out on ordinary carbonate chernozems under winter wheat. No-till technology is applied on more than 200 thousand ha in the Central Ciscaucasia. There are features in the application of this technology related to the composition, properties of chernozems and weather conditions of the territory. An increase in the content of nitrogen (by 20–25 mg kg -1 ) and phosphorus (by 4–6 mg kg -1 ) in the soil was established as a result of the use of No-till compared to plowing for 5 years. The study revealed an increase in the amount of soil microflora: ammonifiers by 2.5-2.7 times; nitrifying agents by 2.8-3.0 times; nitrogen fixing agents of the genus Azotobacter by 4.5-7.0 times; cellulose-destroying microorganisms by 10-12 times in a layer of 0-20 cm of soil. In the seasonal cycle, the largest number of microbes was in the flowering phase of wheat, and the smallest in the spring at the beginning of the growing season. Winter wheat yields during the observation period averaged to 4.61 t/ha for plowing and increased due to the proposed technology up to 5.34 t/ha. The quality of the products (protein, gluten, grain weight) did not change significantly. Calculations of economic efficiency showed that the level of profitability when using No-till technology is 68-72%, and when plowing it is reduced by 25-30%. Profit from 1 ha was 17-18 thousand rubles against 8-10 thousand rubles, respectively
