Abstract:
Groundnut growing soils of Srikalahasti division of Chittoor district were sufficient in DTPA extractable Cu, Fe and Mn. However, DTPA extractable Zn was sufficient in surface horizons and deficient in most of the sub-surface horizons expect P13, P15 and P18 wherein the DTPA extractable Zn was found to be sufficient. The total zinc, copper, iron and manganese content in groundnut growing soils ranging from 10.23 to 98.95 mg kg^-1, 8.00 to 48.00 mg kg^-1, 0.34 to 3.72 per cent and 53.25 to 842.50 mg kg^-1 soil respectively. The available zinc, copper, iron and manganese content in groundnut growing soils ranging from 0.27 to 2.73 mg kg^-1, 0.30 to 8.89 mg kg^-1, 4.58 to 96.54 mg kg^-1 soil and 2.06 to 78.85 mg kg^-1 soil respectively.
