Comparative Physico-Chemical Analysis of Surface and Subsurface Soils from Pilkha Pahad, Surajpur/Surguja District, Chhattisgarh, India
Document Abstract
The present investigation highlights a comparative assessment of the physico-chemical properties of surface (0–15 cm) and subsurface (15–30 cm) soils collected from Pilkha Pahad, Surajpur/Surguja District, Chhattisgarh, India. The study aims to examine spatial and depth-wise variations in key soil parameters, including pH, electrical conductivity (EC), organic carbon (OC), major nutrients—Nitrogen (N), Phosphorus (P), and Potassium (K)—as well as essential micronutrients such as Sulphur (S), Zinc (Zn), Iron (Fe), Manganese (Mn), Copper (Cu), and Boron (B). The results reveal noticeable variability among sampling locations and between soil horizons. Surface soils exhibited comparatively higher organic carbon and nitrogen content, indicating greater biological activity and the accumulation of organic residues in the upper layer. Conversely, subsurface soils showed slightly elevated electrical conductivity and fluctuating micronutrient levels, which may be associated with leaching processes and underlying soil composition. The pH of the soils ranged from mildly acidic to near neutral, reflecting conditions conducive to the growth of most agricultural crops. Overall, this comparative analysis provides important insights into nutrient distribution and soil fertility status in the Pilkha Pahad region. The findings serve as a useful baseline for sustainable soil management and region-specific agricultural planning.
