| Research Abstract |
We studied the effects of aluminum (Al). humus complexes in Andosols on soil properties and plant growth. We confirmed that a large part of the Al-humus complexes is very stable and contributes to accumulation of organic carbon in soils. Alu minum solubility of Andosols was controlled by soil humus or allophanic materials. In the former case, the source of Al was a part of the Al-humus complexes. It was strongly indicated that toxic Al ions to plants are derived from the Al-humus complexes.
