Acid pyrophosphate (pH 2-4) is proposed as an extractant for soil fulvic acids. After XAD treatment of the extractant solution low-ash fulvic acids are obtained in high yield. The fulvic acids were subjected to the high pH and low pH conditions normally encountered in fulvic acid extraction. The observed changes induced in molecular weight distribution, equivalent weight, acid dissociation constants (pKt) and metal binding strength are reported
