 abstract={Significant differences in the chemistry of their waters (pH value, total ion concentration, content of dissolved organic matter, Ca2+ and P-PO34- ion levels) were found between minerotrophic and ombrotrophic mires differing in the mire to catchment area ratio. Conditions for catchment area water feeding to mires determine the trophic type of mires, and affect the chemical composition of marsh waters within particular types.},
