Abstract: Results of Ameliorative effect of organic acids spraying in groundnut on physico - chemical characteristics of calcareous soils have been discussed. A potculture experiment was conducted in Agricultural College, Bapatla, Andhra Pradesh during kharif 2015-16. The experimental soil was calcareous (collected from Vertisol profile), alkaline reaction and low in organic carbon. The treatments comprised of control (T1); FeSO4.7H2O @ 0.25% (T2); citric acid @ 0.25% (T3); acetic acid @ 0.25% (T4); oxalic acid @ 0.125% (T5); ascorbic acid @ 0.25% (T6); hydroxyl amine hydrochloride (T7) were replicated thrice in completely randomized design (CRD) with three replications. Foliar application of organic acids were applied to the respective pots at peak flowering, peg penetration and pod formation stage of the crop growth. The results showed that pH was markedly influenced by the imposed treatments but no significant effect on electrical conductivity (EC), soil organic carbon and cation exchange capacity (CEC), but slight increment was noticed in organic acids treated pots over control.
