EFFECT OF PHOSPHOGYPSUM IN SOME PHYSICAL PROPERTIES OF SOIL

Alaboratory experiment was carried out during 2020 in the laboratories of College Agriculture / University Anbar order to study role phosphogypsum values ​​of saturated hydraulic conductivity, capillary height and water holding capacity soil clay soil. The added mixed with at four levels (without adding, 0.3%, 0.6% 0.9%) by weight treatments were incubated for 90 days adding limits field compensation lost after deplete 50% available water. amount water, has been estimated. increased significantly, which 16.91% addition 0.9% compared treatment without addition. While highest value conductivity 0.35 cm per hour -1at level decreased significantly increase addition, lowest 52 when 0.9%.
