The paper presents studies on the effectiveness of zeolite from the Tatarsko-Shatrashanskoe deposit of the Republic of Tatarstan when introduced into the soil on the basis of the experimental field of the Tatar RIAHP in 2011-2018. The use of zeolite in doses of 10 and 15 t/ha together with mineral fertilizers contributed to the improvement of the agrochemical properties of leached chernozem. Partial neutralization of the exchangeable acidity of the soil (shift of the reaction of the medium by 0.1-0.4 units), a decrease in hydrolytic acidity by 0.2-1.4 mg-eq./100 g, an increase in the amount of absorbed bases by 0.4- 10.8 mg-eq./100 g, an increase in the content of mobile phosphorus by 0.7-14.2% and exchangeable potassium by 1.8-26.7% compared with the control and background options. Partial neutralization of the exchange acidity of the soil (a shift in the reaction of the medium by 0.1-0.4 units), a decrease in hydrolytic acidity by 0.2-1.4 mg-eq./100 g, an increase in the amount of absorbed bases by 0.4-10.8 mg-eq./100 g, an increase in the content of mobile phosphorus by 0.7-31.2% and exchangeable potassium by 1.8-26.7% compared to the control and background variants. The advantage of variants with the addition of zeolite was maintained throughout the entire period of research.
