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.
