Resumen:	Fractionation of fulvic extracts from four Spanish soils using adsorption on insoluble polyvinyl pyrrolidone (polyclar AT) permitted the separation of polysaccharide fractions. No siqnificant differences between fractions were found with respect to elemental analysis, sugar composition, infrared and pyrolysis mass spectra. The most striking feature was the hiqh sulphur content, varying from 3.7 to 9.8%. In addition to monosaccharides (neutral sugars) the isolates consisted of acetylglucosamlne moieties and sulphate ester groups, suggesting that a complex mixture of different polysaccharides and origin were extracted from soils.
