Bangar soils of districts Deoria and Gorakhpur have fair status of available P. The proportion of Ca-P in these soils is much higher in comparison to other forms of soil P. Saloid bound P represents the adsorbed P and highly significant correlation was observed between saloid bound P and available P. Reductant soluble Fe-P and organic P were significantly positively correlated with pH and organic matter respectively. Significant positive correlations were observed between available P and Al-P, Fe-P, reductant soluble Fe-P and Ca-P
