A rapid polarographic method for the determination of extractable zinc in mineral soils is described. Zinc is extracted by shaking the sample with 0.1N HCl for 2 minutes. After the soil extract is made to a known volume and filtered, an aliquot is diluted with electrolyte solution, and the polarogram is recorded. Significant correlations were obtained between extractable zinc in the soil and total zinc in leaves of tung trees growing in the soil.
