lithology - Opis:
- In view of the extremely important role of wetlands, an attempt was made to determine the state of preservation of peat forming processes as a condition for the proper functioning of those areas. By addressing this question, we hoped to determine whether the peat bogs and mires of the Łęczna-Włodawa Plain currently act as carbon sources. The aim of the present study was to compare the ash content and the contents of selected macroand micronutrients in the deposits. The research was carried out in the years 2010-2013 and covered eight peatland areas (three midfield and five mid-forest peatlands). The ash content, as well as the content of biogens, and selected macro- and micronutrients of the studied deposits varied and depended on the type of the deposit forming a given layer. In all the studied deposits, the carbon content was high, especially in the transitional Sedge-Sphagnum peat and the raised pine peat. The marsh layers, in relation to the studied peat minerals and gyttja, were characterized by a lower carbon content, and the restriction of C:N and N:P ratios. In all the studied peat bogs, located in the Łęczna-Włodawa Plain, the accumulation phase dominated, so they do not act as carbon suppliers.
