Results of a soil monitoring survey in landscape farming systems

Abstract

The results of five rounds of a soil monitoring survey of the model object “Repny Log” in the Krasnogvardeysky district of the Belgorod region with a fully developed adaptive landscape farming system are presented. Positive changes in soil fertility indicators have been established. In the soil layer of 0-20 cm, a gradual reduction in the rate of humus loss was replaced by its subsequent growth and stabilization; in the layer of 20-40 cm, an increase in the content of organic matter in the soil by 0.52% (absolute) was statistically significant. There was a significant decrease in pH_s  = 7.57-7.65 with a pronounced alkaline reaction, characteristic of washed away carbonate soils, to the area of neutral values, followed by reliable stabilization (pH_s = 6.31-6.58). Despite the high variability of more dynamic indicators, including agronomically valuable cations Ca²⁺ and Mg²⁺, as well as mobile forms of nitrogen, phosphorus and potassium, they made it possible to identify some features of soil processes and the influence of such elements of adaptive landscape farming systems on them, as systems of protective forest belts, crop rotations, and fertilizers.
