T availability to plants of soil phosphorus and that in phosphatic fertilizers is related to the pH of the soil. Many reports in the literature indicate that phosphorus in rock phosphate is more available to plants in acid soils than in neutral or alkaline soils (,, 2, 3, 4, 6).a Therefore, it would appear that the use of an acidforming nitrogenous fertilizer, such as ammonium sulfate, would increase the availability of the phosphorus in the more insoluble phosphatic fertilizers. Since large amounts of ammonium sulfate and urea are used in mixed fertilizers, this study was conducted to determine their possible effect on the availability of phosphorus in the more insoluble forms.
