“…However, substantial changes in the nature of litter material take place during the transition from the L-layer to the (F+H) layers. Sowden and Ivarson (1962) found that the readily available carbohydrate in fresh litter formed 20 per cent of the carbon initially present but that after 1200 days this proportion was reduced to 10 per cent of the total. The respiratory quotient measurements in the present study also show substantial changes occur in the nature of P. radiata litter between the upper and lower horizons.…”

Laboratory experiments were carried out on the relative decomposition of litters collected from stands with contrasting accumulations of organic matter on the forest floor. Decomposition was measured by the weight loss of sterile litters inoculated with Pholiota and Lenzites, and by the microbial respiration in nonsterile litters.Some differences were measured in litters from stands with dissimilar ages and productivities. The most striking differences in decomposition were those observed in litters from older stands (assumed to be in a steady state condition) of the same age and productivity class but on different soil types. These differences matched the patterns of relative litter accumulations in these stands in the field.The variations found in P. radiata litter decomposition were attributed to nutritionally induced differences in polyphenol complexing of litter materials.

“…Decomposition of forest litters, studied b following changes in the amounts of individual sugars over a period o ? 1200 days(Sowden and Ivarson, 1962) resulted in a uniform loss of ap roximately half of most sugars, This sort of measurement of sugars dPoes not allow for possible syntheses from the litter or other soil constituents which would have the effect of making the plant material seem more resistent to decomposition.…”

Summary Incubation of soil with 14C hemicellulose from rye straw for 448 days resulted in the evolution of about 70 per cent of the substrate as CO2. The two major sugar components of the hemicellulose, xylose (50 per cent) and arabinose (5 per cent), were almost completely decomposed. After 56 days only 5 per cent of the xylose remained and after 448 days only 1‐2 per cent. Similar results were obtained for soil derived from either granitic or basic igneous parent material. Almost 4 per cent of the hemicellulose was transformed to glucose and I per cent to mannose during the first 14 days of incubation. Fine grinding of 14C rye straw increased the extent of its decomposition on incubation but after 448 days 20 per cent of both its xylose and arabinose remained. It is suggested that the isolated hemicellulose is decomposed faster because it has been made water soluble.
