Title

Effects of Some Organic Amendments and Gypsum Application in a Saline and Sodic Soil

Pages

  25-36

Abstract

Remediation of Saline and sodic soils is usually done using leaching of excess salt and physical, chemical and biological methods and by application of mineral and organic amendments. An incubation experiment using poly ethylene columns was conducted to study the effect of using four organic and mineral amendments in a saline sodic soil (SAR=33, EC= 18. 7 dS. m-1). The treatments included: green manure, animal manure, plant residue and gypsum along with control. The water from the area (Akhtar Abad) was used to irrigate the columns. Change in some salinity and sodicity indices and the concentration of some elements in soil solution were measured and compared in soil sub-samples at 40, 80, 120, 160 days of incubation and for 0-10, 10-20 and 20-30 cm depths. The results indicated that all organic amendments especially green manure decreased soil pH compared to control (P<0. 01). Application of all amendments increased soil EC compared to control (P<0. 01). Highest EC was in green manure followed by gypsum, plant residue and animal manure, respectively. The gypsum and green manure decreased the SAR in soil compared to control (P<0. 01). The animal manure treatment did not change SAR but the plant residue treatment significantly increased SAR. In the gypsum and green manure treatments the concentration of Ca and Mg in soil solution increased significantly (P<0. 01).
