Abstract

A rapid method for the determination of plant potassium is presented. It involves the use of a liquid membrane potassium electrode with water extraction. Tri-acid digestion is satisfactory but is slower than water extraction. The electrode method is as accurate as the slower flame photometry method for both extraction techniques.
