USE OF MINERALIZED WATERS FOR IRRIGATION OF THE TERRITORY OF UZBEKISTAN

Abstract

The article describes the development of a flushing irrigation regime achieved by increasing the irrigation rates or the total number of irrigations per season. However, an excessive increase in irrigation rates delays the periods of irrigation, increases the amount of unproductive discharges of water from irrigated fields and contributes to the leaching of nutrients and fertilizers from the root layer into the lower horizons. Therefore, watering rates should be increase by no more than 30% on clayey, heavy loamy and by 50% on loamy sandy loam and sandy soils. Increased watering should be carried out with a pre-irrigation humidity of 0.8 of the lowest moisture capacity. In this case, the increase in the number of irrigations should not exceed 1-2.
