The present investigation was initiated to study molecular weight fractionation of humic compounds isolated from surface samples of an Ultisol (Red Yellow Podzolic soil) and a Spodosol (Podzol), using fine (mol. wt. cutoff 3500) and coarse (mol. wt. cutoff 12000) dialysis membranes and sephadex gel
