Changes in land use and improper soil management have led to severe land degradation around the globe through the modification in soil physico-chemical and biological processes. The study aimed to assess the soil properties of different land use system types. In this regard soil samples (0-30 cm, 30-60 cm and 60-90 cm depth) were collected from different land uses; Natural forest, teak plantation, horticulture (mango and guava) land use system, agriculture (Finger millet cropping system), agri-horti land use system (custard and amla) and agroforestry (melia dubia). Soil collected from different land use systems was analyzed for both physical and chemical properties. The present investigation revealed that the soil texture was sandy clay loam. The mean bulk density of the soils ranged from 1.28 and 1.38 g cm-3 and the mean total porosity ranged from 35.54 - 42.71 per cent. The soil pH was acidic in agriculture (Finger millet cropping system-chemical fertilizer) land use and neutral in other land use systems and the mean electrical conductivity value ranged from 0.06-0.11 dSm-1. The highest mean value (1.11%) of organic carbon was recorded in natural forest and the lowest mean value (0.25%) was recorded in agriculture (Finger millet cropping system-chemical fertilizer) land use. However, the mean values of available N ranged from 141.32 kg ha-1 to 260.02 kg ha-1. Higher mean available P2O5 (88.76 kg ha-1) and K2O (207.59 kg ha-1) were recorded in agriculture land use (Finger millet cropping system-integrated nutrient management). The concentration of secondary and micronutrients were higher in natural forest and tree plantations. The study revealed that conversion of natural forest to different land use systems had adverse effects on soil physical and chemical properties. Therefore, land use systems in the region must adopt a suitable management practice to enhance soil fertility and productivity. [ABSTRACT FROM AUTHOR] |
