; aggregate stability; soil formation in bauxite residue Cite this article as: TIAN Tao, KE Wen-shun, ZHU Feng, WANG Qiong-li, YE Yu-zhen, GUO Ying, XUE Sheng-guo. Effect of substrate amendment on alkaline..., and demonstrated the improvement of vermicompost on the soil quality and crop growth. The amendments play an important role in nutrient availability, physical stability, and microbial diversity of bauxite residue......
is viewed as a promising strategy to stabilize the surface and initiate soil development. However, such approaches are inhibited by high pH, high exchangeable sodium (ESP) and poor nutrient status. Amendment with gypsum is effective in improving residue physical and chemical properties and promoting seed establishment and growth. Application of organics (e.g. compost) can address nutrient......
