Thermal regime of the chornozem ordinary under different technological loads

Abstract

The main indicator of the thermal regime of the soil is its temperature. Different agrotechnical measures (deflection, dipping, irrigation, etc.) to a certain extent influence the temperature of the soil and the thermal regime in general, substantially changing the parameters of its physical properties: humidity, density, spariness. The main objective of the research is a comprehensive assessment of the effect of " no-till " crop cultivation technologies on the change of temperature parameters and the thermal regime of chornozem ordinary in the context of understanding (no tillage) of American scientists who have every reason to be considered authors and founders of these agrotechnologies. Replacing traditional technology with "zero" in the agricultural production of the Steppe causes a decrease in the temperature of the arable layer of soil, especially in daylight hours. The most significant difference in temperature is observed in the upper (0-10 cm) layer, which is determined, first of all, by the conditions of accumulation and heat propagation in the soil. The noted emphasizes the relevance of studying "zero" technologies, changes in the timing of sowing, selection of optimal feeding areas, varieties, etc. That is, all agronomic demands for optimal growth and development of cultivated plants should be reviewed.
