Soil characteristics in the region of Sarnena Sredna Gora Mountains (Southern Bulgaria)

Abstract

The present paper is focused on the soil characteristics of the Sarnena Sredna Gora Mts. In the lower altitude zone, with warmer and drier climate, deciduous (mostly oak) vegetation and heterogeneous rock composition, mainly Cinnamon forest soils are developed. The taller, relatively wetter and colder altitude zone, with beech forests and non-carbonate rocks, is dominated by Brown forest soils. In the highest parts of Sarnena Sredna Gora Mts, with well-developed grasslands, there are Mountain meadow soils. In the lower parts of the relief, made up of upper Cretaceous volcanics and pyroclastites, there is a localized development of Smolnitsa, and in the valleys of the rivers and depressions with low alluvial-proluvial deposits - Alluvial and Alluvial-meadow soils
