| Abstract : A laboratory experiment was conducted to study the effect of organic waste and phosphate fertilizer on the phosphorous phases for three surface soils in the areas of Jurf Al-Sakhar, Shanaffiya and Rushdiya, having different gypsum amounts (700, 140, and 59) mg Gypsum. Kg-1 soil, respectively for incubation period of eight weeks. The results of the study revealed that Octacalcium phosphate (OCP) and Tricalcium phosphate (TCP) when the soil is treated alone, and Di-calcium phosphate (DCP) , Octacalcium phosphate (OCP), and Tricalcium phosphate (TCP) are present in the event of treating the soil with 25% organic substance, while Dicalciumphosphate dihydrate (DCPD) , Octacalcium phosphate (OCP) , and Tricalcium phosphate (TCP) are present in the event of treating the soil with 50% organic substance. The study also revealed the effect of high gypsum amount is clear in the precipitation of phosphorous, And effect of additional amount of phosphorous on the different phases of phosphorous is clear in all the different treatments | ||
