General Physical Properties of Rain-Soaked Soils (On the Example of Zaaminsky District)

The article analyzes the general physical properties of rain-soaked soils of the Zaaminsky district. In conditions of climatic changes on rich soils, and always planting the same type of crop leads to a change in soil properties. The general physical properties of soils are of great importance for determining soil fertility, moisture consumption, mobility, and nutrient absorption. In the upper layer of undeveloped typical gray-earth soils, the density is 1.30-1.32 g/cm3, in the lower layers 1.38-1.40 g/cm3, compacting from top to bottom. On the southern slope of the rain-fed soils, it can be seen that in the arable and sub-arable soil layers it is 1.28-1.32 g/cm3, and in the lower layers it is 1.36-1.40 g/cm3.
