Abstract:

pH and aluminum content in different forms in the soil of the 1st and 2nd generation Pinus massoniana plantations were investigated. The results showed that pH decreased with the stand age and successive rotation increase. Both the exchangeable aluminum and the soluble aluminum content increased with the stand age and successive rotation increase. Humic acid aluminum and organic complexation state aluminum decreased with the increase of successive rotation. Hydroxy monomer aluminum and acid soluble inorganic aluminum had no significant change, and had little effect on soil acidification.

Key words: Pinus massoniana, successive rotations, aluminum forms, pH
