Strategic management of the productivity of agrocenoses in the system of drained agriculture

Abstract

Goal. To improve the zone agrotechnological aspects of growing market-oriented crops in the system of drained agriculture. Methods. The experiment and research were carried out using generally accepted methods of field and lysimeter experiments in agriculture and crop production. Results. The results of experimental research on conducting highly efficient managed agriculture on drained lands, which ensures the creation of the most favorable conditions for the formation of highly productive agrocenoses and the expansion of their productive functions in the Polissia zone, are given. The influence of purposeful optimization of the technological parameters of the main links of reclamation agriculture: water-air and nutrient regimes of the drained soil with the use of the crop rotation factor on the formation of the yield of the commercial grain of commercially attractive crops was studied. Fertilizer systems for intensive technical crops adapted to the conditions of Polissia were improved. The effect of additional regulation of the water-air regime of the drained soil following the requirements of crops (favorable conditions of moisture) on their productivity was studied. The standards for the consumption of biogenic nutrients for crop formation were updated and clarified. The economic parameters of the technologies — the break-even points at which effective cultivation of crops could be achieved — were determined. The productivity potential of the proposed intensive short crop rotation, aimed at market conditions of farming, was evaluated. Conclusions. Strategic management of water, air, and nutrient conditions of the soil with effective plant nutrition in the conditions of a perfect meliorative system makes it possible to increase the productivity of arable land in the Polissia zone by 2.8 times (from 40 t/ha to 110 t/ha), which ensures effective development of plant industry in this territory and rational use of the resource potential of drained lands.
