Agriculture is often responsible for the eutrophication of surface waters due to loss phosphorus—a normally limiting nutrient in freshwater ecosystems. Tile-drained agricultural catchments tend increase this problem by accelerating transport phosphorus through subsurface drains both dissolved (reactive and organic phosphorus) particulate (particle-bound forms. The reduction excess loads from prior reaching downstream therefore necessary. Edge-of-field technologies have been investigated,...
Agriculture has long been considered a great source of nitrogen (N) to surface waters and major cause eutrophication. Thus, management practices at the farm-scale have since attempted mitigate N losses, although often limited in tile-drained agricultural catchments, which speed up transport, while minimizing natural removal landscape. In this context, surface-flow constructed wetlands (SFWs) particularly implemented as an edge-of-field strategy intercept tile drains reduce loads by...
Nutrient losses from agricultural fields have long been a matter of concern worldwide due to the ecological disturbance this can cause surface waters downstream. In paper new design concept, which pairs surface-flow constructed wetland (SFW) with woodchip bioreactor (WB), was tested in relation its capacity reduce both nitrogen (N) and phosphorus (P) loads tile drainage water. A nutrient mass balance comparative analysis were carried out together statistical regressions order evaluate...
Peatlands are a large store of carbon and nutrients. In Ireland, these cover 21% the country’s area have been extensively drained mainly for peat extraction (both industrial domestic). This has intensified decomposition water flow from peat-dominated catchments. Consequently, there an increase in discharge harmful contaminants downstream that may violate EU Water Framework Directive requirements good ecological status surface waters, ultimately disturb aquatic ecosystems. Climate...
Peatlands comprise a significant share of the land surface in Ireland, i.e. 21%. Degradation these ecosystems for horticultural industry purposes has exerted pressure on water quality waters. This occurs due to removal hydrophytic vegetation, drainage and exposure peat aerobic conditions, which latter disturb local regime accelerate decomposition processes. subsequently results leaching carbon nitrogen compounds such as dissolved organic ammonia. Despite above, little study focused...
