THE MANIFESTATION OF PHYSICAL DEGRADATION ON ARABLE LANDS IN UKRAINE (THE LITERARY REVIEW)

Abstract

A review of quantitative and qualitative criteria of physical degradation of arable lands was carried on the basis of own research and literature data about the physical degradation of arable soils. A definition physical degradation was given. The reasons of its occurrence and development were considered. The soil areas of predisposition to the physical degradation were determined. On these areas, where loss of agronomically valuable structure, manifestation of increased cloddy, dissipation and repacking, the application of effective prophylactic measures was justified. Based on the analysis of state of research of physical degradation of arable soils, the urgent problems in Ukraine were indicated. The most pending tasks are the regionalization of information about physical degradation of arable soils, determination of normative parameters of destroying and repacking and development of proposals on implementation of non-degradation agriculture.
