Soil Resources in the South Central Planning Region of the Republic of Bulgaria and their main Сharacteristics
D. Sapundzhiev, Z. Mitreva
Abstract: The object of the study is a territory administratively divided border - one of the six planning regions in Bulgaria, including districts: Kardzhali, Pazardzhik, Plovdiv, Smolyan, and Haskovo. Its area is 22 365 km².
Within these borders (in the environment of the GIS) is digitized soil map of Bulgaria (1: 200000). Established polygons are 31 different soil types. From large-scale (1: 10 000 and 1: 25 000) soil survey of the country (soil essays, fund IPAZR) is extracted and processed a large database of fundamental soil characteristics necessary for Land Evaluation of farmland: texture of the plow and subsoil layers, thickness of humus layer and the soil profile, texture coefficient, soil reaction (pH), humus content, groundwater level, depth to bedrock, erosion or accumulation, salinity, swampiness and stoniness.
With aggregated data new Map of agricultural grouping of soils in the South Central Planning Region is composed with map units - agrosoil groups.
