RECOMMENDATIONS FOR IMPROVING THE ADVERTISING STATE OF IRRIGATED LAND IN THE AREAS OF THE REPUBLIC OF KARAKALPAKSTAN
Keywords:
saline solution, calculation layer, collector, trench, boundary field moisture capacity, ditch module, active soil layer, groundwater level, number of brine washesAbstract
The article provides calculations of the magnitude of the flushing norm supplied to saline soils in two stages: at the first stage, the calculation of the volume of water needed to bring the moisture of the calculated soil layer to the maximum field moisture capacity, at the second stage - the volume of water consumed to displace the dissolved salts from the root layer and the number of leaching, as well as the procedure for submitting a one-time leaching rate to the irrigated lands being leached in the districts of the Republic of Karakalpakstan.
