| Summary: | <strong>Soil samples were collected from calcareous soil fertilized with phosphate fertilizers for many years from different regions of central and southern Iraq and from two depths surface 0-30 and subsurface 30-60 cm. Forms of soluble, ready available, organic and total phosphorus were extracted. Through statistical analysis of different phosphorus forms with soil composition of the studied soils, there was a positive and significant correlation between ready phosphorus, OM and active and total calcium carbonate. The simple correlation coefficient (r = 0.495) and active calcium carbonate (r = 0.539) were weak and significant. (r = 0.292) since calcium carbonate has to do with the adsorption of phosphorus and the formation of metals more stable and stable and less ready readiness Also there was a significant correlation (P <0.05) between organic phosphorus and cation exchange capacity and the simple correlation coefficient (r = 0.426).</strong> |
