The Transfer of Chemical Elements within a Heath-Ecosystem (Calluna vulgaris) in Northwest Germany

摘要: The purpose of this investigation was to describe the element budget a heathland area in Northwest Germany by measuring fluxes elements within ecosystem. following were considered: input precipitation, canopy-drip, mineralisation, ion uptake, litterfall, output with seepage water. H, Na, K, Ca, Mg, Mn, Fe, Al, S, P, CI, NO, NH, Norg analysed, period one year. The results demonstrate high importance deposited nutrients like N (especially No3), Ca and Mg for stability heath-ecosystem. The internal turnover Mn ecosystem mainly took place leaching. No leaching found N, AI, Na. For these litterfall dominant way cycling. The humus layer sink total-N, Fe S. S removed from percolating solution, while especially an inhibition mineralisation found. The balance mineral soil showed that part is Hand source less K From cation/anion storage changes ecosystem-internal H production calculated as 0.4 keq per ha year. It may be traced back uptake dissociation fulvic acids soil. The are discussed respect development, management heath-ecosystems.
