Leenheer and Malcolm (1973) separated a soil fulvic acid into four fractions by electrophoresis. They found a dramatic change in elemental composition, which correlated with carbohydrate content. Thus, the high polysaccharide fraction had high H/C and 0/C ratios, while the low carbohydrate fractions had low H/C and 0/C ratios. All fractions, however, fitted into the accepted...
