Application of DSS in agroecological assessment of the potential of use of chernozem soils in the conditions of the Penza region

The paper discusses the use of a decision support system (DSS) for the purpose of automated agroecological assessment of chernozem soils of the Penza region in comparison with the agroecological classification of soil cover based on standard agrochemical characteristics. The results show the rationality of using DSS, as well as the increased agroecological potential of the analyzed old arable field. Calculations made it possible to identify limiting soil-ecological parameters, such as insufficient content of mobile forms of phosphorus and the density of the arable soil horizon, as well as to calculate the soil-ecological quality rating both for the entire field and for a regular hectare grid.
