Adaptation of soils of the Ciscaucasia to processing systems

The intense technological and natural anthropogenic load on the soils of the Stavropol Territory, leading to a violation of its ecological and production functions and a decrease in fertility, requires a differentiated approach when introducing a particular soil cultivation system for a specific type or subtype of soil. It is proposed to develop a generalized indicator D for assessing the implementation of various systems of basic tillage for different types of soils based on criterion factors: humus content (%), soil density (d, g/cm³), soil resistivity (T, kg/cm²) and soil ped content >10 mm (C, %). As a result of calculations of the indicator D_fact for a specific soil and comparing its values with the range of D_test it was found that for ordinary chernozem and solonetzic chernozem with D_fact equal to 0.889 and 0.932, moldboard plowing is acceptable for certain crops in the crop rotation, dark chestnut and chestnut soils with D_fact equal to 0.828 and 0.778, respectively, it is preferable to cultivate without moldboard with a combination of different methods and depth of soil cultivation, on light chestnut soils (D_fact=0.749), minimization with shallow mulching is recommended.
