SOIL-PROTECTIVE WATER-SAVING TECHNOLOGIES FOR IRRIGATING AGRICULTURAL CROPS ON ERODED SOILS

Abstract

The article deals with the results of the analysis of long-term studies on the study of soil-protective, water efficiency technologies for the cultivation of crops on eroded soils. For the conditions of irrigated and erosion impacted typical loamy soils of a Chirchik-Angren valley, the law of a pliability of the typical loamy soils impacted by erosion is revealed depening on the form of furrows and the size of a jet. The optimum forms of the furrow and size of a jet are determined for condition of typical loamy soils at growing potatoes. The influence of the form of furrow on the contents of organic matter, total nitrogen, common phosphorus in a liquid and firm drain is established the losses of nutritious substances with a liquid and firm drain are revealed depending on elements of irrigation technology. The growth and development of the potatoes is studied. The economic efficiency is determined at cultivation of a potatoes on typical erosion demaged loamy soils.
