    Description: Analytical data of an anaerobic litter decomposition experiment in three waterlogged organic wetland soils. Samples include Phragmites australis leaves, harvested in autumn 2012 from three peatlands in northeastern Germany, i.e. the oligotrophic kettle-hole mire Kablow-Ziegelei, the mesotrophic terrestrialization mire Töpchin Süd, and the rewetted fen Stangenhagen. Phragmites australis rhizomes samples from the same three sites were harvested from living plants in June 2013. Waterlogged organic soils from the three sites were sampled at the same day in June 2013. The decomposition experiment was performed in the laboratory at 20 °C in polyethylene containers (80 cm × 60 cm × 43 cm) filled with the submerged organic soils. The leaf litterbags (1g litter per litterbag) and rhizome litterbags (3 g litter per litterbag) were placed close to bottom of each container for 75 days. At the end of the decomposition time, the litterbags were recovered and gently rinsed with distilled water. After weighting, litters were milled and stored at -20°C. This publication series includes data of the subsequent chemical analyses. These include litter CN-data, determined with an elemental analyzer, mass loss data, determined gravimetrically before milling, data on the peak intensity of the proteinaceous bands Amide I and Amide II, determined via peak fitting of the vector normalized FTIR spectra (Origin Peak Analyzer), the increase of the asymmetric phosphodiester band due to litter decomposition, determined as the peak height of the second derivative difference spectra at 1220 cm-1, lignin phenol concentrations, determined by gas chromatography mass spectrometry after alkaline CuO oxidation of litter and soil substrates, as well as vector normalized FTIR absorption spectra (.abs) and second derivative spectra (.2der) of Phragmites australis plant litters.

    Description: Leaf and rhizome litter was anaerobically decomposed in the soil substrates of three NE_German wetlands. The decomposition time was 75 days. Leaf litter from all sites was decomposed in all substrates, rhizome litter only in its home substrate. The decomposition experiment was done in the laboratory at room temperature by placing litterbags at the bottom of polyethylene containers (80 x 60 x 43 cm) filled with the specific soil substrates. The dataset contains litter CN-data, determined with an elemental analyzer, mass loss data, determined gravimetrically, data on the peak intensity of the proteinaceous bands Amide I and Amide II, determined via peak fitting of the vector normalized FTIR spectra (Origin Peak Analyzer), the increase of the asymmetric phosphodiester band due to litter decomposition, determined as the peak height of the second derivative difference spectra at 1220 cm-1, as well as, lignin phenol concentrations, determined by gas chromatography mass spectrometry after alkaline CuO oxidation of litter and soil substrates.

    Description: Long-term drainage and intensive agricultural use of peatlands make it unlikely that the original sink functions for nutrients and carbon as well as low-nutrient conditions can be re-established within a human time perspective. The data presented here consists of i) soil characteristics, ii) water quality, and iii) mobilization rates for phosphate, dissolved organic matter and methane from soil cores of altogether 12 rewetted inundated peatlands. In addition we included data from a rewetted non-inundated peatland ("Lehstseemoor"). All studied sites are representative of calcareous rich, i.e. groundwater charged peatlands (= fens) found in the lowlands of NE Germany, as well as in other parts of Europe such as Great Britain, the Netherlands or Poland. All sites developed as fens with peat forming small-sedge-brown moss plant communities in their central parts, with sedge and reed stands at the margins, and occurring either at the edge of areas of mineral soils or close to a water course. Approx. 300 years ago the sites were drained for peat excavation or agriculture. The study sites' climate is continental, with a mean annual precipitation of 582-596 mm. The mean daily temperature is 0.7-1.2 °C in January and 18.1-19.1 °C in July (mean of 1991-2007 from the nearby meteorological stations at 'Deutscher Wetterdienst'). Field measurements and an incubation experiment in the laboratory were performed to study the effect of top soil removal on: i) soil and water quality; ii) P mobilisation from soil to porewater; iii) net fluxes of P and dissolved organic matter at the soil-surface water interface; and iv) potential methane production.

    Description: Abstract: Hydrological conditions at the Kleiner Landgraben Valley (Neubrandenburg, NE Germany) were planned to be modified as a part of the Mecklenburg-Vorpommern peatland conservation program. Before restoring hydrological conditions, extensive top-soil removal from drained fens was also scheduled. By doing so, phosphorus, ammonia and methane release from rewetted fens is pretended to be strongly reduced. Moreover, a marked nitrate export reduction is expected, what will decrease N fluxes into the Baltic Sea. Several field and laboratory experiments were performed in the period 2009-2012 in order to evaluate: a) the influence of agricultural activities in the catchment on nutrient load over the lowland fens and nutrient export from drained fens site; b) the groundwater fluctuation at drained fen, c) the phosphorus release potential from the upper peat layer, and d) the impact of top-soil removal on the level of phosphorus concentrations in the surface water of inundated peatlands. Such previous research served as a basis of a laboratory experiment aiming to investigate the influence of the degree of peat decomposition, temperature and N load over nitrate removal and phosphorus turnover. According to our results, nitrate is efficiently removed from highly degraded peat (up to 90 %), whereas phosphorus release decreased at increasing nitrate load and is negligible in less decomposed peat. Moreover, moderately decomposed peat was also observed to have a high nitrate removal potential. Our results provide useful insights for the management of rewetted fens, and can be applied in another agricultural watershed within the NE Germany glacial landscape.
    Description: Zusammenfassung: Im Rahmen des Moorschutzprogramms von Mecklenburg-Vorpommern war eine hydrologische Umgestaltung des Kleinen Landgrabentals bei Neubrandenburg geplant. Dazu waren auch großflächige Flachabtorfungen im entwässerten Moor vorgesehen. Diese Maßnahme sollte dazu beitragen, eine hohe Phosphor-, Ammonium- und Methan-Freisetzung nach einer Moorvernässung zu unterbinden. Gleichzeitig sollte eine deutliche Reduzierung der Nitratausträge aus dem Einzugsgebiet des Kleinen Landgrabens erfolgen, um letztlich die N-Belastung der Ostsee zu senken. Im Zeitraum 2009 bis 2012 wurden daher umfangreiche Freiland- und Laboruntersuchungen zu folgenden Themen durchgeführt: (a) Höhe der Nährstoffbelastung des Moores durch das landwirtschaftlich genutzte Einzugsgebiet und des Nährstoffaustrages aus dem entwässerten Moor, (b) Schwankungen der Grundwasserstände im Moor unter entwässerten Bedingungen, (c) Höhe des P-Freisetzungspotenzials im Oberboden und daraus resultierendes P-Austragsrisiko und (d) Einfluss einer Flachabtorfung auf die Höhe der P-Konzentrationen im Freiwasser überstauter Moore. Diese Ergebnisse waren Grundlage für Laborversuche zur Bestimmung der Nitratreduktion sowie der P-Dynamik in Abhängigkeit von Torfqualität, Temperatur und äußerer Nitratbelastung. Es konnte gezeigt werden, dass der Nitratrückhalt besonders hoch in den vererdeten Torfen ausfällt (bis zu 90 %), aber auch mäßig zersetzte Torfe wiesen noch ein großes Nitratrückhaltepotenzial auf. Gleichzeitig wurde in den vererdeten Torfen bei einer hohen Nitratbelastung die Phosphorfreisetzung stark herabgesetzt wobei die Phosphorfreisetzung in mittel zersetzten Torfen generell sehr gering ausfiel. Auf der Basis dieser Ergebnisse wurden konkrete Handlungsempfehlungen für die Wiedervernässungspraxis abgeleitet, die auf andere Regionen des pleistozän geprägten nordostdeutschen Tieflandes übertragbar sind.
