Abstract
The purpose. To study direction of processes of transformation of sewed peat soils of the Western Polissya at inning and long agricultural use. Methods. Field, laboratory, analysis of variance. Results. Results of long-term researches in influence of long agricultural use on change of water-physical and agrochemical properties of peat soils of the Western Polissya are brought. Conclusions. It is determined that the period and intensity of agricultural use of peat soils influence change of their water-physical and agrochemical properties. So, for the long-term period of researches the density of soil on long pratums has increased in 1,58 times (1958 – 0,210 g/cm3, 2015 – 0,333 g/cm3), and at intense agricultural use (draw through crop rotation) — in 2,1 times (1958 – 0,210 g/cm3, 2015 – 0,446 g/cm3). It is fixed that for more than 50 years of agricultural use peat soils from low- and average-ash were converted in high-ash.

Key words: sewed peat soils, transformation, water-physical properties, agrochemical properties.
