简介
The study focused on the impact of change in land-cover types on soil quality inferred by measuring the relative changes in chemical and physical properties of non-disturbed and disturbed soil system. Soil samples were collected from major land-cover types in the mountain region: natural forest, grassland and cultivated land (arable). The natural forest served as a control against which to assess changes in soil properties resulting from the removal of natural vegetation or cultivation of soil. Soil samples were collected from 0–15 and 15–30 cm depth six times during the year and examined for their nutrient status, i.e. soil organic matter (SOM); total N (TN); available P (AP); available K (AK); cation exchange capacity (CEC), pH and physical properties like particle size distribution, bulk density (BD), and porosity. Significant differences among land-cover types were found for SOM, TN, AP; AK, CEC and pH. Soil …
