Irrigation and Melioration

Abstract

The central element of the agricultural process is the land (soil) as a natural resource, which is the impact of the whole complex of agrotechnical and meliorative activities. The transfer of significant volumes of irrigation water to the areas of new irrigation and development, the abandonment of crop rotations in the absence of deep meliorations led to a significant transformation of natural landscapes, disruption of water balance and balance of nutrients in landscapes, caused land degradation (depletion, salinization). The transition to a new environ-mental and economic model of land use, the priority of which is to combat the causes of land de-gradation, and not its consequences, cannot be implemented on the basis of obsolete ineffective existing land use technologies. The author's vision on the solution of the problems of land use described in the article is given.
