Acomparison Between Normal Gypsum and Phosphatic Gypsum In The Reclamation Of Sodic Soils

Agricultural production in Egypt depends largely on the horizontal extensions. Improving salt affected soils in Egypt is considered an important part in the agricultural security programme.The purpose of this work is to evaluate the effect of different sources of gypsum, and rates of leaching intensities during the reclamation process. Nprmal and phosphatic gypsum wereused in this swork to assess then effect on some chemical properties of some saline -sodic soils.
