Abstract
IN view of the vital importance of carbohydrate fraction of soil organic matter on physical and biochemical properties of soils, a number of workers1–4 have elucidated the composition of soilpolysaccharides by their work on the hydrolysates. The consensus of opinion is that the sugar residues comprise at least 5 per cent of the soil organic matter and the poly-saccharides are composed of galactose, glucose, man-nose, arabinose, xylose, and rhamnose. Brown, Robinson and Johnson5 examined the effect of D-xyloketose on the roots of plants and observed that even a minute concentration of the carbohydrate can perform important physiological functions. The present work was designed to determine the presence of free monosaccharides in soils.
