Abstract
The use of fertilizers in the grain-beet crop rotation for 85 years significantly changed the agrochemical properties of leached chernozem, which were most pronounced in the optimization of the phosphate regime of the soil and least of all – potash. Fertilization changed the nitrogen regime and physico-chemical properties of the soil to a greater extent in a layer of 20–40 cm than –20 cm. It was found that the content of P2O5 in the soil under crops of grain crops was higher than under sugar beet crops, and K2O and pHKCl were less. The greatest changes in the agrochemical properties of the soil under sugar beet crops were noted when using N190P190K190, cereals – with the aftereffect of N135P135K135 + manure 25 t/ha.
