Phosphorus fractionation study in soils of Agricultural Botany Research Farm, Nagpur were studied in relation to soil properties in which10 surface (0-15 cm depth) and 10 subsurface (15-30 cm depth) soil samples collected from studied area were analysed for different physical, chemical properties and different P fractions. Majority of the soils of the study area clayey in nature, neutral to moderately alkaline in reaction, Soil organic carbon was moderate to moderately high in soils, EC values for these soils within safe limit, the free lime content indicating that these soils are moderately calcareous in nature. The available phosphorus content of the soils showed low to moderately high in category. Occluded P had significant positive correlation with sand. Fe-P and Reduct-P had negative significant relation with silt and Ca-P had significant positive correlation. Saloid –P, Al-P, Reduct-P, Org-P and Total-P had significant positive correlation with clay. No one phosphorus form gave significant positive correlation with pH and E.C. Available P was significant positively correlated with Total-P, Organic-P, Ca-P. Organic carbon had significant positive correlation with Total-P, Organic-P, Fe-P, Ca-P. Clay was significant positively correlated with saloid-P, Al-P, Ca-P, Red-P, Organic-P, and Total-P. Silt was significant negatively correlated with Saloid-P, Fe-P, Red-P and positively correlated with Ca-P. Total P and Organic P had significant positive correlation with all the fractions except Occl-P was not showed significant relation with Total-P. All the forms of inorganic P were highly significant and positively correlated with each other except Al-P and Occl-P.
