In work methods of improvement of technology of cultivation of the mixed crops of bean and cereal cultures taking into account influence of a hydromorphism of the soil are shown. We apply the method to identify the trend by linear regression of the dependence of the definable property on the distance. Spatial heterogeneity of pH (KCl) level and humus content is decreasing significantly and is associated with the development of erosion processes on a smooth slope. The significance of differences between the areas of soil properties on the level of pH, humus and exchange potassium is higher than on experimental options. Therefore, differences in soil and geomorphologic factors lead to diversity of agrochemical properties in the field. The most sensitive to the effects of increased acidity are mixed sowings of lupine with barley. Yields of green mass and air- dry weight, number of plants per unit area, and the height of lupine differ between the two areas of soil. Differences are valid for mixed crops and Vitiaz lupine. Indicators of lupine productivity vary in space according to a downward trend. Under the conditions of prevailing medium acid reaction, the most productive was siderat lupine. It is recommended to consider investigated patterns when planning future scientific experiments with bacterial fertilizers and nitrogen-fixing bacteria strains in order to avoid errors in interpretation of results.
