[ 1 ] - آثار تجمعی و باقی‌مانده لجن فاضلاب شهری بر غلظت روی و مس در خاک و گیاه گندم

Sewage sludge application on farmland as fertilizer is commonly practiced in many countries. Sewage sludge is rich in macro and micronutrients. However, high concentration of heavy metals in sludge may cause pollution of soil, groundwater and human food chain because of toxic metals uptake by crops. The objective of this study was to determine residual and cumulative effects of sewage sludge on...

[ 2 ] - اثر لجن کنورتور و سرباره ذوب آهن بر عملکرد ذرت و جذب برخی عناصر کم‌مصرف گیاه در یک خاک آهکی

Many researchers have reported positive effects of converter sludge and slag, two by-products in Isfahan iron melting factory. In this work, the optimum rate of application and the availability of some essential elements (for plant growth) in the converter sludge and slag for corn were investigated. The converter sludge contains about 64% Fe ІІ and ІІІ oxides and some other essential elements f...

[ 3 ] - اثر باقی‌مانده و تجمعی کودهای آلی بر غلظت نیتروژن، فسفر و پتاسیم در خاک و گندم

Compost and sewage sludge contain high concentration of plant nutrients and, thus, have been used extensively as an inexpensive fertilizer. The objective of this study was to evaluate cumulative and residual effects of compost, sewage sludge and cow manure on nitrogen, phosphorus and potassium in soil and wheat. The experiment included compost, sewage sludge and cow manure, each applied at 3 ra...
