The purpose of this study was the comparison of the efficiency of four phosphatic fertilizers (PA, MAP, NP, TSP) in their ability for available-P supplying to soil and plant. Calcareous soil (Typic Torifluent) from Al-Ashaki project was chosen for this study. Fertilizers were incubated in a constant temperature room at 25 C.G., and their results shown that available-P increased in soil with increasing of fertilizers applied. The supplying of available-P to the soil fertilizers was in the following orders PA, MAP, NP, TSP. The increase in fertilizer level caused an increasing in dry matter, plant length and adsorbed-P values, where the effect of fertilizers on plant growth was in the order PA, MAP, NP, TSP.
