Draining peatlands for agriculture transforms them into significant carbon (C) sources. Restoring drained peatlands is increasingly recognized as a climate action strategy to reduce terrestrial greenhouse gas emissions. Restoration efforts often requ

The potential and limitations of the Borehole Nuclear Magnetic Resonance (BNMR) technique as an in situ measurement for peatland soil characterization was tested in 163 boreholes at four selected peatlands in Denmark. The BNMR data effectively differ

Excess nitrogen (N) losses from intensive agricultural production are a world-wide problem causing eutrophication in vulnerable aquatic ecosystems such as estuaries. Therefore, Denmark as one of the most intensively farmed countries in the world has

Artificial drainage of agricultural fields represents a major flow path way of both water and nutrients which may contribute to eutrophication issues in the recipient waters. Several studies have shown that riparian lowlands (alluvial plains, wetland

Eutrophication of natural water bodies is moderated by transformation of nitrate (NO 3 −) in riparian wetlands, which serve as filters of infiltrating drain water from upland agricultural areas. The present study comprised field observations, labor
