Abstract: In order to investigate the alkali buffering action of several soil types, the author adopted the potentiometric method, and preliminarily studied buffering and influencing factors. The results showed that: buffering capacity to alkali of different soil types followed the order of yellow brown soil> paddy soil> Shajiang black soil> moisture soil. The buffering capacity of different fertility Shajiang black soil and paddy soil followed the order of high fertility> middle fertility> low fertility. The buffering capacity of different soil organic matter contents followed the order of high content of organic matter> middle content of organic matter>CK. The buffering capacity of the same soil type was proportional to soil fertility and the content of organic matter.
