The extracting reagent suitability is most important factor for the availability of potassium in soil and related soil fertility also. For that a depth wise soil sample was analyses by different available K extracting reagents as well as soil fertility status. The soil pH, EC, organic carbon, available N, P,K and S were found in considerable quantity in surface (0-15 cm) and sub-surface (15-30 cm) horizons soil. The fractionation study of different extractants for available K was 0.01M CaCl2 extractable K, HNO3 extractable K, EDTA extractable K, water soluble extractable K, 1 M NaCl extractable K, Mehlich III extractable K and total K, in the soil determine the availability of the soil potassium. Under this study, normal and neutral ammonium acetate extractant was found to appear for considerable amount of available K among the extractants for soils of Bairaia sub-division soil as per two village viz. Sripalpur and Tiwari Ke Milki based pedon samples.
