Abstract
The present study was undertaken to assess the soil fertility status os soils under sugarcane-ratoon-wheat cropping system. Soil samples were collected from farmers fields at three depths viz., 0-15 cm, 15-30 cm and 30-45 cm and analysed for various soil properties. Results revealed that soils were sandy clay loam to clay loam in texture, neutral in soil reaction and non saline in salt content. Mean values of CEC 15.96, 13.13 and 10.80 C mol (p+) kg-1, SOC 4.57, 3.93 and 2.95 g kg-1, available nitrogen 263.01, 209.90 and 173.73 kg ha-1, available phosphorus 15.37, 12.49 and 9.00 kg ha-1, available potassium 156.43, 118.16 and 102.11 kg ha-1, DTPA Zn 0.49, 0.35 and 0.21 mg kg-1, DTPA Fe 9.53, 7.71 and 5.28 mg kg-1, DTPA Mn 8.20, 6.80 and 5.20 mg kg-1 and DTPA Cu 0.99, 0.74 and 0.56 mg kg-1 were recorded at 0-15 cm, 15-30 cm and 30-45 cm, respectively. Soils under this cropping system were low in available nitrogen content and medium in available phosphorus and potassium content. Among DTPA extractable micronutrients soil were deficient in available zinc while sufficient in available iron, manganese and copper content.
