Abstract
The present study was undertaken to assess the soil fertility status of the soils of KVK Muzaffarnagar. Soil samples were collected from two depths viz., 0-15 cm and 15-30 cm and analysed for various soil properties. Results revealed that soils were sandy loam in texture, neutral to slightly alkaline in reaction, non-saline and low in soil organic carbon content. Mean values of CEC, SOC, available nitrogen, available phosphorus, available potassium and available sulphur were 11.22 and 9.62 C mol (p+) kg-1, 0.17 and 0.13 g kg-1, 260.16 and 208.14 kg ha-1, 30.86 and 27.30 kg ha-1, 100.94 and 107.89 kg ha-1 and 13.51 and 12.84 kg ha-1 recorded at 0-15cm and 15-30 cm depth, respectively. The mean of DTPA extractable zinc, DTPA extractable iron, DTPA extractable manganese and DTPA extractable copper were 0.28 and 0.31 mg kg-1, 0.97 and 1.22 mg kg-1, 2.14 and 1.78 mg kg-1 and 0.23 and 0.19 mg kg-1 recorded surface and sub-surface depths, respectively. Soils are low in available nitrogen and potassium and medium in available phosphorus status. Cationic micronutrients such as iron, copper and zinc contents were found deficient in range, whereas manganese content was found to be sufficient.
