Influence of treatments on the physical and chemical properties of the soil in the Dry-Steppe zone of the Lower Volga region

Резюме: The assessment of the influence of soil cultivation on the accumulation of NPK in fallow fields is given on light chestnut soils in the Volgograd region. Changes in the nutrient regime of the soil under the influence of various weather conditions of the year are revealed. It was found that the higher content of nutrients in steam fields is mainly due to non-fallow tillage, in some years, which has optimal moisture supply, and the control (dump) option in comparison with lower indicators for surface treatment in all years of research. The main comparison in the change of nutrients in steam fields is observed for different methods of tillage. For comparison, the article presents the results on the accumulation of NPK processed by the direct sowing system, i.e. NO-TILL without the intervention of mechanical tillage.
