    Abstract: The geochemical features of the chronosequences of soils in forest-steppe and steppe pedogenesis
under the influence of zonal types of vegetation have been studied. A new method for the integral assessment
of the biogeochemical transformation of soils in the chernozem sequence over time according to the most
informative list of trace elements which are accumulated or washed away by soil solutions from humus
horizons of soils was proposed. A priority list of five trace elements which is recommended for inclusion into
the monitored parameters in the system of soil and environmental monitoring of agricultural land is
presented. It is shown that periodic diagnostics of trace elements deficiency in agricultural lands and its
correction by adding micronutrients to compensate for the loss of the most rapidly consumed trace elements
is required. A priority list of chemical elements useful for plants (Ca, Zn, Mg, Ni, P, Mn) as monitoring indicators
for the conditions of erosive agrolandscapes was substantiated.
