摘要：

The use of insoluble polyvinylpyrrolidone and isoelectric focusing in the study of humic substances is reviewed. Chromatography on insoluble polyvinylpyrrolidone is widely used to characterize humic materials extracted from soils, organic fertilizers, soil amendments and organic wastes in order to evaluate their degree of humification. The isoelectric focusing technique is employed mainly to evaluate the stability of the organic matter in organic wastes before their use in agriculture.
