Based on the results of soil and agrochemical surveys, the state of soil fertility of agro-podzolic soils of the northern forest-steppe under conditions of intensive farming has been studied. The generalization of the soil properties of individual indicators in an amount of 44-148 values characterizing the given territory was carried out by methods of mathematical statistics. The features of the analyzed soils are discussed by dividing into two groups - fundamental and stable. The first group includes a combination of genetic horizons of the soil profile. This group also included the content of clay fraction and physical clay, the pH of the salt extract. The group of stable soil properties includes the humus content, the sum of absorbed bases and hydrolytic acidity. The results of typical soil characteristics and properties, depending on the duration and intensity of the impact of agricultural processing, their indicators are a criterion for assessing and optimizing soil conditions for crops. In this case, the actual data processed by the statistical method is more informative than the specific measurements.
