Abstract:
Soil survey was undertaken to study the vertical distribution of plant nutrients in the soil pedons of Groundnut growing areas of Vepurikota microwatershed in Chittoor district to understand nutrient supply capacity of soils. The results revealed that plant available N was deficient in all the pedons whereas P was sufficient in all the pedons. Available K and S in these soils were deficient to sufficient in all the pedons. The DTPA extractable Cu and Mn were found to be above critical limits in surface and sub-surface horizons of all the pedons. The available Zn was deficient to sufficient in all the pedons in both surface and sub-surface horizons except pedon 1 and the available Fe was found to be above the critical limits except in pedon 4. All the micronutrients were higher in surface soils than in subsurface soils except in pedon 1 for Zn, and pedon 4 for Fe.
