| ABSTRACT |
| A rhizobox system was used to determine the distribution of micronutrients (Fe, Mn, Cu and Zn) across the rhizosphere of wheat (Triticum nestivum). The available contents of Fe and Mn in the rhizosphere were raised by addition of manure or chemical fertilizer combined with manllle, but those of Cu and Zn were hardly affected, which might be an important reason why manure addition could improve the Fe and Mn nutrition status of plants. Several possible mechanisms for the increase of the availabilities of Fe and Mn in the rhizosphere due to manuring are discussed as well. |
