Comparative evaluation of the effectiveness of the integrated use of agrochemicals on spring wheat crops depending on the zonal features of the soil cover of the Republic of Tatarstan

This paper presents the authors' own ideas on methods to increase the effectiveness of the use of agromeliorants and mineral fertilizers on Yoldyz spring wheat crops, confirmed by the results of studies in three zonal soils of the Republic of Tatarstan (leached chernozems, dark gray and gray-forest soils). In the course of stationary field experiments, it was found that liming of slightly acidic soils, phosphorization and the introduction of zeolite as a prolongator of agrochemicals, combined with the use of calculated norms of mineral fertilizers for the planned yield of 3.5 t/ha of grain of the ob-ject of research in agrometeorological conditions in 2020 ensured the receipt of 3.6-4.2 t/ha of grain from each hectare of arable land, corresponding to the second (leached chernozems) and to the third quality class (dark gray and gray-forest soils).
