:    Effect of Addition Pressmud and Gypsum by Product to Reclamation of Highly Calcareous Saline Sodic Soil
In saline sodic soil, salts tend to accumulation in the surface soil and may be affecting on soil properties. A laboratory experiment was conducted in soil columns to ameliorate the soil properties and reduce soluble salts by application of ‘‘pressmud” (PM), ‘‘gypsum by product” (G) singly and/or in combinations (PM+G) on the highly calcareous salinesodic soil (pH= 8.22, ECe= 48.5 ... إقراء المزيد
