Database on the formation of the physical and mechanical state of dark chestnut soils under the influence of processing, fertilization and irrigation, nutrient and water regime of the soil. Models of soil cultivation, fertilization and irrigation systems in agrocenoses on irrigated lands. Final report. Scientific and methodological recommendations for the formation of soil cultivation systems, irrigation and fertilization in agrocenoses on irrigated lands. Purpose: obtaining new knowledge of changes in agrophysical properties, nutrient and water regime of dark chestnut soils and the phytosanitary state of crops, to create a database on the formation of effective soil fertility under the influence of the methods and depth of the main cultivation, fertilization systems and irrigation regimes. During 2016-2020 in a 4-field crop rotation on irrigation, the following were investigated: five systems of main tillage - dump and dump-free at different depths, differentiated - 1 and 2, and shallow single-depth; three fertilization systems: without fertilizers, with application - N82,5P60, per hectare of crop rotation area and - N120P60 and generally recognized irrigation regimes. The total water consumption of crops per 1 ha of the crop rotation area ranged from 5093 to 5294 m3/ha. Water consumption for the creation of one ton of products under control amounted to 1134 m3/t, with differentiated-1 processing 1064 m3/t, or less by 6.2%, and with a shallow one-ton, they increased by 33.2% with an indicator of 1644 m3/t. The highest productivity of crop rotation according to fertilization systems (3.71, 6.92 and 8.50 grain units) with the level of profitability of 48.4%, 86.2 and 110.1% was provided by differentiated-1 system Product Description popup.authors Bulygin Dmitro O.
