The Integral Criteria of Estimations of the Land-Improvement Status of Black Soils of West Siberia

M. T. Ustinov

Abstract

The results of natural and land-improvement status of the soils of West Siberia allowed distinguishing the integral criteria of estimations of the land-improvement status of black soils: water permeability of the soil-earth (ameliorating) layer and sodostability of the plough-layer. The introduction of these criteria, as supplements to the generally accepted ones, into the methodology of land-improvement soil science allows one to reveal the ecological land-improvement potential of the black soil and to some extent predict their response to irrigation.
