On the data basis of field experiences on stationary sites have been revealed the changes of morphology, agrophysical, and agrochemical properties of drained peat soils in Soligorsk district. In the article was shown a character of anthropogenic transformation of soils and soils cover during draining and agricultural using. It was given a characteristic of the morphology of the organic soil profile. It was conducted a place of a new soils types formed on objects of drainage in a new soil classification, it was analyzed evolution of soils cover of drained lands. Drainage and long intensive use of peat-marsh soils of Soligorsk area under arable land in grain cultivated crop rotations leads to a number of irreversible processes: reduction of capacity of a peat deposit; mineralizations of organic matter and increase in ash content; increase in density of ground; qualitative change of a total chemical compound arable horizons. All this promotes, at first, formation of agro-peat soils on a place of drained peat-marsh low-power soils with their subsequent evolution in residual-gleization (degro-peat soil) with the various content of organic matter. The analysis of dynamics of parameters of agrochemical properties of arable horizons investigated почв testifies to prevalence subacidic soils on an investigated area and in general reflects the tendency wich are characterized in last years for all arable lands of republic - insignificant ash content and exchange acidity (PH in KCI) and reduction of the content of mobile potassium and phosphorus
