Methodological aspects of assessing the agroecological state of soils under conditions of long-term agricultural use

Abstract

Methodological aspects of assessing the agroecological state of zonal soddy-podzolic soils of various granulometric composition under conditions of long-term agricultural use are presented. The assessment is based on the calculated deviations of the indicators of humus-granulometric ratios and buffer capacity in the acidic and alkaline range of arable land soils from the initial (natural) state, followed by determining the degree of change in the value of one or another criterion (“weak”, “moderate”, “strong” and “very strong”) and the calculation of transformation coefficients and soil stability. The obtained criteria can be used to improve the system of indicators for assessing and monitoring the agroecological state of soils in the educational process, when conducting scientific and monitoring studies, developing measures to preserve soil fertility and their rational use, and building models of soil fertility.
