Abstract
In model experiments under forest ecosystem conditions, samples of partially decomposed forest litter and soil from a 0–10 cm layer containing 14C-labeled organic matter were selected. The label was introduced in the form of low molecular weight water-soluble organic substances of individual nature – glycine, uracil and glucose together with unlabelled plant litter in nylon bags. The experiment was carried out in the late autumn period on the territory of the Malinsky forestry, 20 km south-west of Moscow, on a medium loamy sod-podzolic soil. For the study, samples were taken from two selection periods – 40 days after labelling and after two years. The selected samples were extracted and separated into soil organic matter fractions containing 14C in their composition, followed by radiometry. The results showed differences in the transformation and incorporation of radiocarbon of the studied products – glycine, uracil, and glucose into different fractions of soil organic matter of low molecular weight water-soluble substances, depending on their nature.
