Abstract:

During 1998-99, a field experiment was conducted to investigate the effects of residual Processed Municipal Waste Leachate (PMWL) on growth and yield of wheat (variety Roshan). The treatments consisted of residual amounts of 0, 150, 300 and 600 t/ha of PMWL and a residual N, P, K, and Zn fertilizer treatment in a randomized block design with 3 replications. In 1998, rice seedlings were transferred to 34 m plots. After harvesting the rice, wheat was seeded in the same plots without any new treatment. Processed municipal waste leachate and fertilizers were applied during the rice growth. Residual effects of PMWL increased the amounts of available macro- (N, P and K) and micronutrients (Fe, Cu, Zn and Mn) in soil which, in turn, promoted the grain and straw yield of wheat compared to the control. Straw and grain yield increased from 1.67 and 3.50 t/ha in control to 3.93 and 12.80 t/ha in 600 t/ha of PMWL, respectively. The residual effects of PMWL had no significant effect on heavy metals concentrations in plant. The effects of residual PMWL in the soil were proportional to the amount of leachate applied. However, more investigations are recommended to fully understand heavy metals effects on soil, plant, and environment.

اثر باقی مانده شیرابه زباله بر ویژگی های خاک و رشد عملکرد گندم

اثر باقی مانده شیرابه زباله بر گندم (triticum aestivum)، پس از کشت برنج، در یک طرح بلوک های کامل تصادفی با پنج تیمار و سه تکرار بررسی گردید. تیمارها عبارت بودند از باقی مانده مقادیر صفر، 150، 300 و 600 تن در هکتار شیرابه زباله، و نیز یک تیمار کودی شامل اثر باقی مانده کودهای اوره، سوپرفسفات تریپل، سولفات پتاسیم و سولفات روی. برای اجرای طرح کرت هایی به ابعاد 4×4 متر با فواصل سه متر ایجاد، و اواخر...

اثر شیرابه زباله بر عملکرد و ترکیب شیمیایی ذرت و اثر باقیمانده آن بر بعضی ویژگیهای خاک

The moisture content of urban solid wastes in Iran is very high. A large volume of leachate is, therefore, produced in the process of converting these wastes into compost. The leachate contains relatively large amounts of organic matter, plant nutrients, soluble salts as well as small amounts of some heavy metals. The effects of urban solid waste leachate on growth and yield of corn and heavy m...

اثر شیرابه زباله بر عملکرد و ترکیب شیمیایی ذرت و اثر باقیمانده آن بر بعضی ویژگیهای خاک

شیرابه زباله که در فرآیند تبدیل زباله های شهری به کمپوست تولید می شود حاوی مقدار قابل ملاحظه ای مواد آلی، عناصر غذائی، املاح محلول و مقدار کمی از بعضی عناصر سنگین می باشد. اضافه کردن شیرابه زباله به خاک گرچه می تواند باعث ارتقاء سطح باروری خاک شود ولی در عین حال می تواند موجب شور و آلوده شدن خاک گردد. اثر شیرابه زباله بر عملکرد و جذب عناصر غذائی ضروری و عناصر سنگین به وسیله ذرت در یک آزمایش مزر...
