Аннотация: Investigated the main hydrophysical characteristics (OGH), density, botanical composition and ash of peat-ground (Sapric Rheic Histosols) of lowland peat of the floodplain of the r. Yakhromas within the territory of the Dmitrovsky Department of the All-Russian Research Institute of Reclaimed Lands (Moscow Region) on grassed-hypnova and hypnova peat (Sapric Rheic Histosols (Lignic)) rich in carbonate, peat-rich agro-mineral peaty (Sapric Rheic Drainic Histosols (Mineralic)), i-ray zones, i-ray zones, and i-ray zones, i-rayons, agromineralic (Pets) on woody peat underlain by grass, sedge and woody peat deposits (Sapric Rheic Histosols (Lignic)). OGH was determined by capillary meters in the range of moisture pressures from 0 to 80-90 kPa. OGH of peat-earths in the indicated range is a dependence close to l In the semilogarithmic image, on which, unlike mineral soils, such a characteristic point as bubbling pressure is practically not expressed, it is shown that the OGH of peats is significantly determined by their density: more dense samples of peat with the same pressure of moisture had a higher humidity , which indicates an increase in water retention. An increase in the degree of decomposition and ash content also leads to an increase in water retention, but to a much lesser extent than peat density.
