%X As a result of high annual average temperature and plentiful rainfall, acidity of soils in south China was intensive and a large number of exchangeable aluminum (Al) was accumulated in the soils. Impacts of exchangeable Al on soil properties, soil fertility, and Al toxicity to living organisms have received ample attention. Limestone fertilization has long been regarded as an effective measure to alleviate the toxicity of soluble Al to crops planted in acid soils. Acquirement of the status of pH as well as ...
