ESTIMATION CHARACTERISTIC OF THE BELARUS POLESYE PEAT ON CENTURIES-OLD TIME LAG OF DRAINAGE LAND RECLAMATIONS // Tomsk State Pedagogical University Bulletin. 2009. Issue 3 (81). P. 126-131

Eight objects of peat with 38-453 years after drainage on the territory of Belarus Polesye were selected. In article are presented data of estimation their water-physical and biochemical characteristics, as well as factious composition of organic matter and of soil nitrogen forms of the peat soils on different stages of agricultural use after drainage. Examination these objects have shown that in process of agricultural use of the dranned peat soils their full degradation does not occur. The most active phase of peat organic matter mineralization stopped approximately after 50 years of the use, but after 200 years approaches the stabilization of the biochemical processes. Under correct and rational carry out of farm production (sparing processing of soil, optimal combination organic, macro- and micro-fertilizes, selecting the forage cultures) these lands possible to use indefinitely long. As a result on place of the dranned peat shaping barren soils and forecasts does not occur, predicted in a short time formation of semidesert on place all achieving worn-out peat, as minimum, exaggeration.
