The paper aimed to present the some aspects on changing the pedomorphological and physical indicators of upper profile of cambic chernozem under soil tillage in a period of 60 years. Soil tillage have directly influence on the size composition of it’s, both arable layer and in the immediate vicinity layer. Content of 1.0-0.05 mm fraction in the horizon A of fallow soil is 2.2 times higher, in horizon B - 2.5 times higher, than in arable soil. Cambic chernozem from forest belt in the fallow condition has remediated the original textural properties within a period of 60 years. Using in the arable the tillage of chernozem cambic led to argillisation of upper layer. Content of fraction <0.01 mm constitutes in the horizon A - 60.2%, in horizon B - 59.7%. Soil texture is a quality virtually unchanged, so agricultural and reclamation technologies must adapt to the textural specifics of soils. Role of the soil texture is apparent from the characterization of particle size fractions.
