Abstract: Influence of different doses of mineral fertilizers and biological products on the nutrient status of the soil depending on the basic soil cultivation methods during chickpeas cultivation is studied. Experiments were carried out on southern chernozem according to the generally accepted methods. It is shown, that application of monoammonium phosphate had a significant advantage in improving nutrient status of the southern chernozem front of the ammonium nitrate. It was revealed that the starting dose of nitrogen applicated with phosphorus during various types of the main tillage, influences on the symbiosis of chickpeas with nodule bacteria. The best way of basic soil cultivation for nut, after spring wheat is plowing to a depth of 25–27 cm. The highest yield of chickpea (1.70 t/ha) was when combined: seeding after ploughing during application of ekstrasol, seed inoculation with rizotorfin and starter treatment with monoammonium phosphate in a dose of N12P50. To gain control was 0.61 t/ha or 56.0%. Application of nitrogen-phosphoric fertilizers during seed treatment with ekstrasol in a dose of N12P50 is effective, productivity was more than in control by 0.41 t/ha or 37.6%. In the options of experience where risotorphine was not applicated, tubercle bacteria were not formed. Ammophos contributed to the accumulation of phosphates, in the phase of seed formation there were 19.7–19.8 mg/kg of phosphoric acid in the soil. In the north-west zone of the Rostov region a system of fertilizer with a nitrogen starting dose of N12 together with phosphorus P50 during sowing is low-cost, has not negative effect on properties and composition of southern chernozem and does not contribute to pollution of the natural environment.
