COMPARATIVE ASSESSMENT OF METHODS FOR IMPROVING SOIL FERTILITY AND PRODUCTIVITY OF ARABLE LAND IN GRAIN/FALLOW ROTATION

Abstract

Results are given from investigations carried out in the forest-steppe zone of Transbaikalia into the effect of various fallow types on changes in water-physical properties, nutritive regime and biological activity of soil, and productivity of crops in crop rotation. Under conditions of Transbaikalia, the most efficient methods for improving soil fertility and productivity of arable land can be solved using soil-protective technologies: use of conservation tillage techniques, introduction of full fallows and perennial grasses to crop rotations and application of cereals straw. It has been established that these technologies contribute to increasing organic matter in soil by 0.34-0.58% and coefficient of structural properties by 0.13 - 0.31 units, create favorable conditions for activation of biological processes, provide higher characteristics of productivity and cost effectiveness (1.58-2.07 tons per ha of feed units, net income of 243-570 rubles per ha, profitability of 7-18%).
