Most of the soils have medium to high erosion ability - II-III degree, and the pH is neutral to slightly alkaline (7-7,8). Few are weak and moderate acidic pH (6,7-5). Soils are mostly shallow to moderately deep, poor in nutrients. In the region of Kardzhali main pollutants are heavy metals from mining-processing and metallurgical business activities of “Gorubso-Kardzhali” - AD and LZC - AD, Kardzhali.
