This study was conducted at college of Agriculture – university of Anbar during fall season 2010 to study possibility of using some organic wastes and mineral materials in treatment of saline soils and it application in irrigation. This study including laboratory experiment which design to determine the best treatment of saline water by using different plant organic wastes and mineral materials (calcite and gypsum). Four sources of plant organic wastes which included: shimblan plant, cob of corn, wheat straw, sunflower steems for the total decomposition. All organic wastes were mixed with the mineral materials (20% calcite and gypsum). Saline water was added with dilution ratio of 1:10 , 1:20 , 1:30 , 1:40 and 1:50. The EC , pH and SAR at the extract were measured. Results of this studded showed
1. The best contribution of organic wastes in decreasing value of EC of saline water were by cob of corn and wheat straw while sunflower steems and shimblan showed no contribution in this respect under the conditions of this study.
2.Using organic wastes resulted in decrease in pH values in all treatments.
3. SAR values were different with different types of organic wastes the rating of decline were cob of corn, wheat straw, sunflower steem and shimblan.
