Abstract
The purpose. To specify criteria and specifications of physical degradation of soils, to develop offers to perfecting normative basis. Methods. Analytical, comparative, statistical, Results. Conceptual approaches to searching criteria of physical degradation are justified. On the basis of comparative long study of virgin soil (long fallows) and arable soils some criteria are offered which can be used for diagnostics of physical degradation. The survey of quantitative and quality criteria of physical degradation of arable soils is realized. Assessment is made of propensity of soils to physical degradation and speed (intensity) of development of degradation processes on concrete instances. Diagnostic parameters are specified and preliminary specifications of physical degradation of arable soils are determined. Conclusions. On the basis of own researches and literary data some offers are made (for discussion and refinement) about the list of indexes and specifications of physical degradation of arable soils.

Key words: physical degradation, arable soils, criteria, parameters, specifications.
