Estimates were made of water balance as well as balance of dissolved forms of: N (including N – NO3, N – NH4, Norg), K, Na, Ca, Mg, S – SO4 and Cl. The following undrained mires were examined: two with minerotrophic fen and one with ombrotrophic-transition bog. Also a drained minerotrophic mire was studied. It was observed that nitrogen outflow from undrained mires was considerably smaller. The mire with ombrotrophic-transition bog could retain a substantial part of a scanty inflow of the examined elements, while mires with minerotrophic fen – upmost a tiny part of a rich inflow mainly from catchment basin. Drained minerotrophic mire was no longer apt to retain a majority of elements, nitrogen in particular.}, type={Text}, title={The processing of elements by mires in agricultural landscape: mass balances based on sub-surface hydrology}, URL={http://www.rcin.org.pl/Content/82272/PDF/WA058_88168_P2840-T38_Eko-Pol-A-Nr-1.pdf}, volume={38}, number={1}, journal={Ekologia Polska}, publisher={Polish Scientific Publishers}, keywords={elements, mires, inflow, outflow, drainage, ground water flow}, }
