Release Behaviour of Phosphorus and Its Fractions in Different Phosphorus Status Soils

Phosphorus is owned by all forms of life and allure contribution towards aiding the native land fertility and experiencing it, is well known. With transition of time, P added to soil experiences transformation into differing unavailable forms. Native P compounds, few being highly insoluble are generally unavailable for plant rude answer. The availability of phosphorus to the plants depends on soil characteristics, soil pH, soluble iron, container and manganese, calcium minerals, natural resources, activities of microorganisms thus chance of P may change according to soil types. Knowing the changes in P parts especially in low and in extreme P status soils is much more influential for P availability to plant. Therefore, the release behaviour of planet seen at dawn and its fraction indifferent P status soils was evaluated over 5 weeks under laboratory process of early development periods using a sequential fractionation process. The results of the experiment revealed that the content of feasible P and different P parts were higher in high P rank soil as compared to reduced P status soil. Among the miscellaneous P fractions, Ca-P was the dominant part in both soils. The release of accessible P was first increased up to 21 and 28 days in reduced and high P rank soil, respectively and the release of various forms of P fractions in both soils raised up to 28 days subsequently incubation and therefore decreased with further increase in development period.
