Физико-химические исследования и экологический мониторинг почв, распространённых вокруг Каттакурганского водохранилища

Changes in the physicomechanical properties and ameliorative state of the soil were studied using the Kat- takurgan reservoir as an example; the degree offossil, the density of irrigated lands, the dynamics of the groundwater lev¬el by years, the ameliorative state and the location of salts by layers were studied.According to the results, the indicator of soils with an inadequate ameliorative

state increasedfrom 4.22% to 5.58%. It was justified that the level of groundwater salinity is mainly between 0-1 g/l and 1-3 g/l.It is scientifically substantiated that the main effect of the Kattakurgan res-ervoir on soils is formed by the accumulation of salts, the effect on the physicomechanical properties is relatively small.
