The aim of the work is to substantiate the scientific and methodological foundations of the safe functioning of agrocenoses on irrigated lands for determining the parameters for the use of basic processing systems, water and nutrient regimes of the soil in short rotation crop rotations. As a result of the research, the following was developed: basic information on changes in the physical and mechanical properties of irrigated soils, the accumulation and consumption of moisture and nutrients by the soil, depending on the methods and depth of soil cultivation, irrigation regime and fertilization systems, a database on the formation of agrocenoses on irrigated lands, depending on degree of anthropogenic load. Scientific and methodological recommendations for the formation of agrocenoses on irrigated lands. It was found that the most effective set of crops that saturate the crop rotation with the least deterioration of the agrophysical properties of the soil is a crop rotation with two fields of corn for grain, soybeans and winter barley using the main dumping at different depths in the crop rotation. Under the same conditions, the most rational use of moisture to create one ton of crop (721-972 m3/t) was revealed. A significant increase in the coefficient of water consumption (up to 962-1354 m3/t) was noted in crop rotation with 50% saturation with grain and industrial crops and up to 1007-1640 m3/t in crop rotation with a specific weight of 25% of cereals and 75% of industrial crops. In the crop rotation, where the saturation of cereals is 75%, due to the incorporation into the soil of twice the mass of corn stalks, as well as grain and soybean straw, a high content of nitrates, mobile phosphorus and potassium compounds is formed, which is associated with a large intake of nutrients during mineralization Product Description popup.authors Bulyhin Dmytro O Vozhehova Raisa A Hranovska Ludmila M Luzhanskiy Igor Yu Mishukova Lidiia S Maliarchuk Anastasiia S Pysarenko Pavlo V Tomnitsky Anatoliy V popup.nrat_date 2021-01-17 Close
