Open publisher page 3 citations

Abstract

The specificity of the group and fraction composition of the organic matter in peat soils drained to a different extent that have developed for a 20-to 25-year period of hydro-and forest amelioration was characterized using the methods of multidimensional statistics. The differences in the organic matter of the soils studied are mainly determined by the contents of humic and fulvic acid of fractions 1 and 3, as well as of hemicelluloses and cellulose. The degree and depth of the humification are inversely related to the soil moisture and directly related to the peroxidase activity.
