Abstract

Ivanov, P., Hristova, M. & Hristov, B. (2025). The soils of the South Central Planning Region in Bulgaria – distribution, characteristics, limiting degradation factors. Bulg. J. Agric. Sci., 31(6), 1079–1085

The paper presents a brief description of the soils in the South Central Planning Region of Bulgaria. Soil differences and their distribution are indicated through analysis of printed and digital map material. The established information is supplemented with a graphic representation of the soils using a geographic information system (GIS). Some of the morphological features of soils, as well as several of their chemical and physicochemical characteristics, are highlighted. A few fundamental natural and anthropogenic factors related to the influence of degradation processes leading to a decrease in soil fertility are presented.

Keywords: soil units; GIS; soil characteristics; degradation processes; soil fertility
