Abstract:
An evaluation of Physico-chemical properties of 27 soil samples from 3 different blocks of Malda district (West Bengal) in different depths (0–15, 15–30 and 30–45 cm) was carried out during the year of 2020–2021. The present investigation was objectified as determination of soil Physico-chemical properties to analyse the soil fertility status with finding out the deficiency and toxicity of different soil nutrients. Soil samples were analysed using standard laboratory techniques and statistical analysis. Findings have shown sandy loam to loam soil texture and bulk density range of 1.33–1.81 Mg m^–3 with good Water Holding Capacity (44.71–59 %). Soil pH is slightly acidic to slightly alkaline with a mean value range of 6.29–8.15 and the Electrical Conductivity suitable for all crops and free from salinity with a mean value of 0.12–0.37 dS m^–1. Soil Organic Carbon was medium to high range (0.45 – 0.9 %) than standard, due less decomposition of organic matter of the soil. Available Nitrogen (mean value range of 250.1 – 504 Kg ha^–1), Phosphorus (mean value range of 8.73–21.6 Kg ha^–1) and Potassium (mean value range of 161.3 – 279.6 Kg ha^–1) are adequate whereas, Sulphur (13.23–31.32 Kg ha^–1) is deficient. Calcium and Magnesium are sufficient (7.27 – 11.87 and 4.63 – 8.13 meq/100g). In case of micro-nutrients, Iron (5.8–12.15 mg Kg^–1) and Copper (0.16 – 0.69 mg Kg^–1) content are sufficient whereas, Zinc content (0.16–0.87 mg Kg ^–1) is slightly deficient.
