Abstract
The colorimetric procedure of Jacobs and Hoffman for determining K precipitated as the cobaltinitrite affords a rapid and convenient method for samples of plant tissue. The method compares favorably with the chloroplatinate method with respect to precision; and the saving of time and labor, permitting the handling of a larger number of replicates, results in a much greater final precision.This publication has 1 reference indexed in Scilit:
