Tasks of Polygon of agricultural technologies:

Polygon of agricultural technologies serves as a scientific and educational platform for students, teachers of agricultural universities of the country, and agricultural production specialists. We will expand our partnership with the leading agricultural universities of the country - RSAU – MTAA or RSAU – MAA named after K.A. Timiryazev, Stavropol State Agrarian University, Kuban State Agrarian University and others. In the coming years, we aim to get 130-150 c/ha of winter wheat grain on these soils.

Results:

In most experiments, in the best variants, over 50 years of fertilizer application, the soil acidity (pHKCl) decreased from 4.2 to 5.9, the content of mobile phosphorus increased by 9-10 times - from very low to high, and potassium – from medium to high, while the humus content was stabilized at 1.75-2.00%.

The increase in soil fertility contributed to a consistent increase in the yield of winter wheat from 2.5 to 7.2 t / ha, and in favorable years to 8-9 t/ha, an increase in the payback of mineral fertilizers from 9.0 to 16.6 kg / kg of active substance of mineral fertilizers.
