چکیده

استفاده از زئولیت و سوپرجاذبدر خاک می‌تواند در کاهش آلودگی منابع آب مفید باشد. بدین منظور این تحقیق در سال 1397 و در قالب طرح آماری بلوک‌های کاملاً تصادفی و به‌صورت دو آزمایش مستقل انجام شد. تیمارهای مورد استفاده شامل دو تیمار در سه سطح مختلف و چهار تکرار بود و در مجموع با 24 لوله پلی‌اتیلن به قطر 5/10 سانتی‌متر و ارتفاع 50 سانتی‌متر در شرایط غیر اشباع در مزرعه تحقیقاتی دانشکده مهندسی علوم آب دانشگاه شهید چمران اهواز انجام شد. تیمارها شامل زئولیت پتاسیمی و سوپر جاذب نوع A200 در سه سطح صفر (شاهد)، 2 و 5 گرم در کیلوگرم خاک بود. کود اوره به‌صورت سرک و از بین 15 آبیاری، در آبیاری‌های 1، 6 و 12 به ستون‌های خاک اعمال شد. در پایان هر آبیاری نیترات خروجی اندازه‌گیری شد. نتایج نشان داد که اثر سوپرجاذب در تمام آبیاری‌ها و زئولیت غیر از آبیاری 6 در سطح 5 درصد بر کاهش آبشویی نیترات معنی‌دار بود. و تیمار 2 گرم سوپرجاذب در کیلوگرم خاک غیر از آبیاری‌های 6 و 7  نسبت به تیمار 2 گرم زئولیت در کیلوگرم خاک عملکرد بهتری را در جلوگیری از آبشویی نیترات داشت. به‌طور کلی تیمارهای 2 و 5 گرم زئولیت در کیلوگرم خاک به ترتیب 20و 29 درصد و تیمارهای 2 و 5 گرم سوپرجاذب در کیلوگرم خاک به ترتیب 48 و 64 درصد نسبت به تیمار شاهد در جلوگیری از آبشویی نیترات مؤثر بودند.

چکیده [English]

The application of zeolite and superabsorbent in the soil can be useful in reducing water pollution. For this purpose, this research was carried out in 2018 with two treatments in a completely randomized block design. Each treatment consists of 3 different levels and 4 replications. Totally 24 polyethylene pipes with 10.5 cm in diameter and 50 cm in height were used under unsaturated conditions at research farm of Faculty of Water Sciencs Engineering, Shahid Chamran University of Ahvaz. Treatments in this study included potassium zeolite and A200 superabsorbent at three levels of 0, 2 and 5 g/kg of soil. Urea fertilizer was applied to the soil in irrigation 1, 6 and 12 from 15 irrigation events. At the end of each irrigation event, nitrate effluent was measured. The results showed a significant reduction (at 5% level) of nitrate leaching in the superabsorbent and zeolite treatments in all irrigation events (with the exception of No. 6 irrigation event in zeolite). Superabsorbent treatment (2g/kg of soil) had better performance than the zeolite treatment (2g/kg of soil) in terms of preventing nitrate leaching, with the exception of irrigation events of 6 and 7. In general, zeolite and superabsorbent treatments (2 and 5 g/kg of soil) reduced nitrate leaching (20 and 29%) and (48 and 64%), respectively, as compared to the control treatments.
