| Abstract: | Effects of different kinds of anion exchange membrane (AEM) on soil P extracted by AEM (AEM P) were investigated in three soils (Cumulic Andosol, Yellow soil, and Gray Lowland soil). There was no significant difference in AEM P among the AEMs tested (BDH-Prolabo 551642S, AGC Engineering Selemion AMT, and AGC Engineering Selemion AMV). The AEM P was greater than water-soluble P in all soils. Although AEM P was greater than Truog-extractable P in Cumulic Andosol, the reverse was true in the Yellow soil and Gray Lowland soil. |
