| چکیده | ||
| یکی از مهم‌ترین تهدیدهای منابع آب‌وخاک در هر کشور، فرسایش خاک و هدررفت مواد غذایی است. استفاده از اصلاح‌کننده‌ها، به‌ویژه مواد آلی، از راهکارهای مؤثر برای جلوگیری از آن است. به همین دلیل در این پژوهش تلاش شده است تا اثر دو اصلاحکنندهی آلی خاک، یعنی زغال زیستی و کود گوسفندی، در دو شدت بیشینه‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌ی 51 و 65 میلیمتربرساعت در عرصه و به کمک شبیه‌ساز باران ارزیابی شود. نتایج نشان داد که در شدت 51 میلیمتربرساعت هیچ تفاوت معنی‌داری در تیمارها به وجود نیامده است، حال‌آن‌که با افزایش شدت به 65 میلیمتربرساعت، اصلاحکنندهی زغال زیستی سبب 64 % کاهش بین متغیرهای حجم رواناب، بار معلق و ضریب رواناب و کود گوسفندی نیز سبب 76% کاهش در متغیرهای حجم و ضریب رواناب و 74% کاهش در بار معلق در تراز اعتماد 99% شد. | ||

| چکیده [English] | ||
| Soil erosion and nutrient loss threaten the soil and water resources worldwide. Application of soil conditioners, particularly organic amendments, is an effective way to mitigate this problem. This study was undertaken to assess the effect of application of two organic amendments, biochar and ship manure, under two rainfall intensities of 51 and 65 mm/h by using a rainfall simulator on intact soil. No significant difference was observed in the treatments at 51 mm/h, while with an increase in the intensity to 65 mm/h, the biochar amendment made a decrease of about 64% in the suspended load and runoff coefficient; sheep manure reduced the runoff coefficient and suspended load by about 76% and 74%, respectively at the 99% significance level. | ||
