A sequential dissolution technique and a prolonged extraction method were used to investigate aluminium (Al) release from 4 Haplic Acrisols in southeastern China. The results show that the order of acidification of the 4 soils is: Tunxi soil>Yongchun soil>Shengxian soil>Ninghai soil. The amount of exchangeable Al is directly proportional to the extent of soil acidification. Al was released from both organically bound and inorganic Al pools after acid input. During several initial cycles of...[Show more]
