Effect of tank silt and wood ash on physical and physico-chemical properties of coastal sandy soil under groundnut cultivation

A field experiment was conducted during the rabi season of 2023 on sandy loam soil to study the effect of tank silt and wood ash on soil properties, including physical and physico-chemical properties under groundnut cultivation. The experiment consisted of ten treatments with tank silt, wood ash and K2SO4 foliar application with different levels of RDK tested in randomized block design (RBD) with three replications. Results indicated that the soil's physical properties were not significantly influenced by the imposed treatments. Among the physico-chemical properties of soil, soil reaction (pH) did not show significant influence from the treatments, whereas, electrical conductivity, cation exchange capacity and organic carbon content were found to be improved due to the application of tank silt and wood ash.
