Abstract: | Introduction Springer1) used in his earlier work acetyl bromide for separating true humic substance from soil organic matter, and proposed to designate the degree of decomposition (Zersetzungsgrad) by such a numeral Ch Ct x 100, of which Ct, was total carbon, and Ch was carbon insoluble in acetyl bromide. In Germany this numeral, abbreviated as Z. G., has been widely applied. |
