The paper presents the results of ranking the criteria for assessing the ecological functions of soils. This ranking is presented for the first time. The authors propose to evaluate the ecological functions of soils by the degree of variability of their basic properties compared to the background using a six-point scale. The object of the study is leached chernozem, low-humus, powerful loamy soil on a cover carbonate loam, occurring on the territory of the Botanical Garden of Voronezh State University named after B.M. Kozo-Polyansky in the city of Voronezh under the collections of tree-shrub introducers. Based on the proposed criteria, the following biogeocenotic functions of leached chernozem have been evaluated: 1. Soil functions as a source of nutrients and compounds; 2. Depot of moisture, batteries and energy; 3. Stimulant and inhibitor of a number of biochemical processes; 4. Soil functions due to its physicochemical properties. Based on the results obtained, practical recommendations have been proposed for improving the biogeocenotic functions of leached low-humus powerful loamy chernozem as a whole and especially under coniferous, shrub and coniferous-shrub vegetation
