Nature of carbohydrates associated with water-stable aggregates of two cultivated soils

The distribution and composition of carbohydrates were investigated in slaking-resistant aggregates and in particle size fractions of two silty soils from the Paris Basin, France. Three hydrolysis procedures, involving hot water, dilute acid and concentrated acid were used and hydrolysates were anal...

Zusammenfassung:	The distribution and composition of carbohydrates were investigated in slaking-resistant aggregates and in particle size fractions of two silty soils from the Paris Basin, France. Three hydrolysis procedures, involving hot water, dilute acid and concentrated acid were used and hydrolysates were analysed on a HPLC system to further assess the origin of the carbohydrates. Results showed the predominantly plant origin of the particulate organic matter (>50 μm) and the microbial origin of the clay+silt fraction (
