Title: Change in Phosphates Solubility Isotherm in Some Calcareous and Gypsiferous Calcareous Soils.

Abstract: Four calcareous soil samples and two gypsiferous calcareous soil samples were selected from certain areas in Saudi Arabia. Dilute phosphoric acid was added to the soil in order to give a concentration equivalent to 0, 20, 200 and 2000 mgP/kg soil. It was found that water soluble P continued to increase with phosphorous application and decrease in pH and solubility product values were noticed. The ability of these soils to saturate with dicalcium phosphate depends on the sorption P-capacity of each soil under study.
