Abstract

The paper presents a comparison of the total porosity of typical chernozems affected by different uses. Calculations to determine the porosity of chernozems showed that the total porosity is approximately 50% (fluctuating within the smallest significant difference), which ensures good agronomic properties of the soil. However, the upper horizon in the variant with the fallow should be noted, as it has the highest value of total porosity - 48% among the upper A-horizon (0-20 cm) of all soils. The values of the porosity coefficient in the studied chernozems approximately coincide, with some insignificant variation within the profile. However, there is also a variant of typical chernozem on fallow land with the highest value (0.94) of gap space in the upper genetic horizon.
