A Study of Effect of Barley Straw as Organic Filter on Reduction of Drainage Water Nitrate

In recent years nitrate was reported as most important source of pollutant of soil and water resources because of nitrogen agricultural fertilizers leaching. On the other hand treating and reusing of drainage water is necessary because of the extreme water resource reduction. So aim of this study was reduction of nitrate from drainage water with barley straw as an organic filter. Barley straw combined with sandy clay soil in two method (layered and mixed), three volume (10, 20, and 30) percent and investigated quality of influent and effluent water from treatments through the time. On the base of results, optimum combination percent of barley straw with soil for layered and mixed treatment was 20, 30%; respectively that removed nitrate more than 81, 77%. The ammonium concentration of the drainage water was decreased with elapsed time and variation of the pH and EC were function of the influent. So application of the barley straw in layered method as a bioreactor to remove nitrate from drainage water recommended because of low price, ease availability and usage without any worry about side effect like strong variation in pH and EC.In recent years nitrate was reported as most important source of pollutant of soil and water resources because of nitrogen agricultural fertilizers leaching.
