Abstract: | Summary Five acid soils of Hawaii, having histories of heavy P applications were equilibrated with graded quantities of Zn. Amounts of adsorbed Zn were extracted with a single extraction of 0.005M DTPA. The data indicated that most of the added Zn was in available form. Prior P applications either had no effect on recovery or slightly increased it. The results substantiated the earlier findings that P-induced Zn deficiency could not be due to precipitation of Zn as insoluble Zn–P compounds in the soils. |
