Title : Quantitative Evaluation of Soil Quality Based on Soil Nutrients and Physico-chemical Characteristics of Soils in Kandi District of Punjab

Abstract :

Kandi regions are dominated by different soil types varying in fertility status due to soil erosion owing to undulating topographical features. For assessment of soil nutrient status of study area, the soil sampling was conducted to investigate the variation in macro nutrient, micronutrient and physicochemical characteristics of soil. Soil sampling were carried out in three tehsils of SAS Nagar with three different types of soil, viz., Sandy loam, Silt loam and Loam soil. A total 105 soil samples were collected from surface soil (0-15 cm) for analysis. The results reported that the soils slightly acidic to slightly alkaline (5.9 to 8.5) in the whole range. Organic carbon (OC) was found to be varying from low to very high (0.18 to 0.78 %). Phosphorus and sulphur were significantly found Silt loam soil. DTPA-extractable Fe, Mn and Cu were found to be dominant concentration in all soils whereas the deficiency of Zn was found under all existing soil types. Interestingly, OC have also significant positive correlation with Nitrogen (r = 0.353), Sulphur (r = 0.212), Zinc (r = 0.257) and Iron (r = 0.327). Soil quality based on principal component analysis reported Fe, Cu, Mn, EC and K are major dominating parameters to be considered of soil in Kandi region.
