Organic soils in peatlands store a great proportion of the global soil carbon pool and can lose carbon via the atmosphere due to degradation. In Germany, most of the greenhouse gas (GHG) emissions from organic soils are attributed to sites managed as grassland. Here, we investigated a land use gradient from near-natural wetland (NW) to an extensively managed (GE) to an intensively managed grass...

The Falkland Islands (Long 57-62°W; Lat51-53°S), land area 12,200km have a cool temperate (2.2°C.9.4°C), oceanic climate. Rainfall varies between 400-800mm and is lowest in spring. The islands were glaciated only on the highest ground with surrounding land affected by a periglacial environment. During the Post-glacial period acid, organic soils have formed mainly because of low temperature and ...

The main aim of this study was to determine, during extreme hydrological conditions, the source(s) of acids, sulphate and metals (alkali and alkaline earths) in the Munsala stream (western Finland) draining mainly acid sulphate soil, peat and till. Samples were collected at 6 sites along the main stem on 3 high-flow and 3 low-flow events, and were analysed for the required chemical and isotopic...

Knowledge of the hydrochemical dynamics of the trace metal manganese (Mn) in upland catchments is required for water quality management. Stream water Mn and other solutes and flow were monitored in two upland catchments in northern England with different soils: one dominated by peat (HS7), the other by mineral soils (HS4). Maximum Mn concentrations occurred at different times in the two catchme...

background: lemon verbena (lippia citriodora h.b.k.) is an aromatic and medicinal plant of family verbenaceae, which cultivated in north region of iran. objective: evaluation of phytochemical characters in lippia citriodora h.b.k. plantlets affected by propagation methods (micro-propagation and stem cutting) cultivated in different soil type (peat moss and mixture soil). methods: this study was...

[1] Permafrost melting is occurring in areas of the boreal forest region where large amounts of carbon (C) are stored in organic soils. We measured soil respiration, net CO2 flux, and net CH4 flux during May–September 2003 and March 2004 in a black spruce lowland in interior Alaska to better understand how permafrost thaw in poorly drained landscapes affects land-atmosphere CO2 and CH4 exchange...

Astiani D, Burhanuddin, Taherdjadeh M, Curran LM. 2016. Effects of water table level on soil CO2 respiration in West Kalimantan forested and bare peatland: An experimental stage. Nusantara Bioscience 8: 201-206. Peatland forest is one of ecosystems that are susceptible to the alterations of water regimes. Our previous study demonstrated that hydrologic conditions are predominant variables in de...

Forestry harvesting on peats is known to result in significant losses of soil phosphorus (P) to adjacent waters, and the issue is becoming an increasingly serious concern as peatland forest stocks mature and reach harvestable age. One potential solution could be the use of low-cost P recovery techniques based on the chemical precipitation and/or adsorption of the dissolved fraction of soil P, w...
