INTEGRATED LAND RECLAMATION IS THE BASIS FOR TECHNOLOGICAL SUPPORT OF FOOD SECURITY AND PRESERVATION OF SOIL FERTILITY

The purpose of the research is to identify bottlenecks and identify areas of both scientific research and practical actions for the technological provision of agriculture with integrated land reclamation. The main achievements of scientists and researchers of the Federal Scientific Centre for Hydraulic Engineering and Land Reclamation named after A.N. Kostyakov, carried out over the past 5 years on the base of state assignment, are presented in the paper. The proposed scientific developments are both fundamental and applied in priority. Comprehensive research is aimed at soil fertility restoration and improvement within existing reclaimed lands, as well as unused areas return into cultivation. Prospect agro-reclamation technologies and techniques to provide degraded soils cultivation are proposed for these purposes, such as nature-approach agrotechnical and reclamation techniques to provide sustainable improvement of soil fertility; agro-phytomeliorative techniques to restore degraded pasture ecosystems and estuarine lands; methods to protect crops from droughts and frosts. Combined low-volume irrigation systems and an intelligent automated water management system (IAWMS “Water Use”) have been developed and implemented, Bioengineered structure for drainage flow and waste water purification and mineralization reducing in the rice irrigation system are suggested. New hybrids of corn and soybeans have been created, as well as technologies for their cultivation.
