Abstract
A comprehensive system for the determination of N, P, K, Ca, Mg, Na, B, Cu, Fe, Zn, S and F in plant tissue is presented. A wet ash procedure using sulfuric acid and hydrogen peroxide permits determination of N, P, K, Ca, Mg, Na, B, Cu, Fe and Zn in 1 digest. S and F are determined in solutions of separate dry ashings. The use of leaf analyses and its limitations are discussed.This publication has 5 references indexed in Scilit:
