INFLUENCE OF FIELD CROPS CULTIVATION TECHNOLOGY ON MOISTURE - PHYSICAL PROPERTIES OF COMMON CHERNOZEM SOIL IN THE FIRST COURSE OF FIELD CROP ROTATION IN THE ZONE OF UNSTABLE MOISTENING IN STAVROPOL REGION
The purpose of the research was to study the influence of traditional technology and the No-Till technology of crops cultivation on the content of productive moisture and soil density in the 1st rotation course of the four-field crop rotation system. The study was carried out on the common chernozem soil in the zone of unstable moistening in Stavropol region. The results of the study showed that when cultivating crops without soil tillage, the moisture to be used by plants to form the yield, accumulated and retained better than in case of sowing by using traditional technology with the basic and pre-sowing soil treatments. It is noted that this is facilitated by plant remains of the preceding crops left on the field after harvesting. The density of the treated and untreated soil has been studied and it is proved that the soil density is within the range of optimal values for plants' growth on chernozem soil.
