Soil-Protective Water-Saving Technologies For Watering Agricultural Crops On Eroded Soils

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 liability of the typical loamy soils impacted by erosion is revealed depending 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 the condition of typical loamy soils at growing potatoes. The influence of the form of a furrow on the contents of organic matter, total nitrogen, common phosphorus in a liquid and firm drain has 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 are studied. The economic efficiency is determined at the cultivation of potatoes on typical erosion damaged loamy soils.
