Soil Cover Structure under Oak Groves in the Urban District of Voronezh

摘要

The spatial organization of soil cover in a mountain oak grove of the urban district of Voronezh has been investigated. The complexity and specificity of soil cover structure caused by geological and geomorpho-logical conditions and vegetation has been shown for three key sites. It has been established that combinations of gray forest-steppe soils of different types and varieties dominate under the canopy of natural oak forests. Dark gray and gray forest-steppe soils on cover loess-like loams with favorable physicochemical and chemical properties are the best soils for the growth of oak groves of site classes I and II.
