Use of methods of mathematical modeling at agrophysical assessment of soil cover

A stochastic approach to agrophysical assessment,based on the analysis of water and air regimes in soils, is proposed. External initial conditions on upper and lower boundaries of soil profile (precipitation, evapotranspiration, water outflow etc.) and experimental water retention and permeability data set in mathematical models allow to predict moisture changes, as well as to evaluate and optimize water and air conditions of plant growth. Using data on Vladimir Opolie and Ivanovo region soil cover as an example, а high heterogeneity of agrophysical properties is shown.
