| Research Abstract |
Under an intensive fertilization system in the arable lands, a great amount of P sources has been accumulated and fixed in the soil as an organic P (phytin) and insoluble P as Al-, Feand Ca-P. The potential of crop to solubilize and absorb the soil P should be defined in order to establish the sustainable crop productivity in these agricultural lands. In the present study, we showed possibility of acquisition of these P compounds in several crops such as corn, peanut and sesbania and also evaluated the P and N supply potentials of leguminous crops associated with rhizobia as green manures to the succeeding crop.
