Environmentally Safe and Resource-Saving Water Regulation Technologies on Drained Lands

Abstract

In modern conditions of climate change and agricultural use of drained lands, there is a need for efficient production with the introduction of new or improved technologies for growing economically attractive crops that can ensure sustainable harvests, environmentally safe production, and minimize all costs, including water resources. By implementing a resource-saving technology of water regulation of drained lands during the cultivation of perennial grasses, the saving of water resources is 48,700 m3/year, the consumed electricity is 5.7%/ year. The saving of water resources during the cultivation of corn for silage was 670 m3/ha, and the costs of operating the sluices decreased by 2-3 times. Compliance with the technological parameters of water regulation during the cultivation of paiza, amaranth and fodder beans made it possible to increase the yield of cultivated crops by 15-20%, ensure the saving of water resources by up to 25% and obtain the economic effect.
