THE CHANGES OF CHEMICAL PARAMETERS OF PEAT-FORMING PLANTS DURING DECOMPOSITION PRO-CESSES ON KARST-SUFFUSION MIRES OF THE MIDDLE-RUSSIAN UPLAND
UDC 552.577
Abstract
The variety of biosphere functions of mire ecosystems is associated with the intensity of vertical growth of peat deposits, which is correlated with the rate of decomposition of plant remains. This process depends on the complex of ecological conditions and accompanies by changes in the chemical composition of plants. For studying of dynamics of the chemical parameters of the main peat-forming plants on the model karst-suffusion mire, an experiment was conducted with the laying of plant material in the peat. Plant samples were placed in peat to a depth of 5–7 cm in different parts of the mire, which is corresponded to the original place of species growing. After 1 and 2 years, the samples were removed from the peat and elemental analysis was carried out on the CHN-analyzer Carlo Erba 1100, ash content was determined by weight method and the degree of decomposition of plant remains was done by microscopy method. The results shows, that during the 2-year experiment the degree of decomposition of plants remains was changed by different ways. The herbs are least resistant for decomposition in the peat, but sphagnum mosses are the most resistant. The process of decomposition of plant remains is accompanied by a decreasing of ash content in vascular plants and increasing in sphagnum mosses, which is associated with their ability to accumulate surface runoff substances and atmospheric dust. During the transformation of plant material the content of carbon and nitrogen are changing. The C/N ratio indicates an uneven proportion of carbon and nitrogen at different stages of decomposition in different plant species, which correlates with the degree of decomposition.
