Abstract-The approach to taking into account the spatial variability of soil properties during decision making in agroecosystem management has presented. The approach is based on the quantitative indicators of plants production process (wheat crop) obtained by using a dynamic model of the agricultural plants production process AGROTOOL. The studies were conducted in the environment of a special software package that is based on the integration of the dynamic model AGROTOOL and GIS. Computer simulations data allowed identifying the conditions under which the influence of the soil hydrophysical characteristics variability on the crop production exists or disappears.
