Chemical Amendment of Dairy Slurry For The Control of Phosphorus in Runoff From Grassland
(2011-09-28)Phosphorus (P) loss from grassland to a waterbody can adversely affect water quality. Land application of dairy cattle slurry can result in incidental P losses to runoff in addition to increased chronic P losses from soil ... -
Chemical amendment of pig slurry: control of runoff related risks due to episodic rainfall events up to 48 h after application
(Springer Nature, 2013-03-26)Losses of phosphorus (P) from soil and slurry during episodic rainfall events can contribute to eutrophication of surface water. However, chemical amendments have the potential to decrease P and suspended solids (SS) losses ... -
Contamination and spatial variation of heavy metals in the soil-rice system in Nanxun county, southeastern China
(MDPI AG, 2015-01-28)There is an increasing concern about heavy metal contamination in farmland in China and worldwide. In order to reveal the spatial features of heavy metals in the soil-rice system, soil and rice samples were collected from ... -
Developing and validating a decision support tool for media selection to mitigate drainage waters
(Elsevier, 2019-07-26)The nitrate nitrogen (NO3-N) and ammonium (NH4-N) and/or dissolved reactive phosphorus (DRP) load in drainage water from farms can be managed by reactive or biological media filters. The nutrient content of the drainage ... -
Developing farm-level sustainability indicators for ireland using the teagasc national farm survey
(Walter de Gruyter GmbH, 2016-01-01)In the context of an expanding, export-dependent agri-food sector, indicators of sustainable development and intensification are necessary to measure, assess and verify the comparative advantage afforded by Ireland's natural ... -
Developing the eu farm accountancy data network to derive indicators around the sustainable use of nitrogen and phosphorus at farm level
(Springer Nature, 2015-05-28)This study uses a national farm survey which is part of the European Union (EU) Farm Accountancy Data Network (FADN) to develop environmental sustainability indicators in the use of nitrogen (N) and phosphorus (P) across ... -
Environmental response of an irish estuary to changing land management practices
(Elsevier BV, 2015-07-01) -
Evaluation of the fertiliser replacement value of phosphorus-saturated filter media
(Elsevier, 2021-01-12)The use of filter media to adsorb phosphorus (P) from nutrient-rich waters is an effective, simple and low-cost method to recover and reuse P as an inorganic fertiliser replacement. Although it is assumed that the saturated ... -
Forest clearfelling effects on dissolved oxygen and metabolism in peatland streams
(Elsevier BV, 2016-01-01) -
Impact of P inputs on source-sink P dynamics of sediment along an agricultural ditch network
(Elsevier, 2019-12-19)Phosphorus (P) loss from intensive dairy farms is a pressure on water quality in agricultural catchments. At farm scale, P sources can enter in-field drains and open ditches, resulting in transfer along ditch networks and ... -
Influence of stormflow and baseflow phosphorus pressures on stream ecology in agricultural catchments
(Elsevier BV, 2017-07-01) -
An investigation into the growth of lolium perenne L. and soil properties following soil amendment with phosphorus-saturated bauxite residue
(Springer, 2022-04-07)Industrial by-products, such as bauxite residue, may be used to treat phosphorus (P)-enriched water and wastewater. Once fully saturated, they may be reused as P fertilisers. This study aimed to investigate the effectiveness ... -
Linking soil erosion to instream dissolved phosphorus cycling and periphyton growth
(Wiley-Blackwell, 2017-06-05)Phosphorus (P) is a limiting nutrient in freshwater systems and when present in runoff from agricultural lands or urban centers may contribute to excessive periphyton growth. In this study, we examined the link between ... -
A novel method to rapidly assess the suitability of water treatment residual and crusted concrete for the mitigation of point and nonpoint source nutrient pollution
(Elsevier, 2019-07-02)Freshwater ecosystems worldwide are at risk of becoming degraded as a result of excessive inputs of phosphorus (P) associated with terrestrial activities. This study describes a novel methodology to rapidly assess the ... -
Phosphorus and organic soils under grassland production: Assessment of phosphorus losses for a more sustainable agriculture
(NUI Galway, 2019-06-19)The intensification of agriculture in Ireland aims to increase the exports of dairy and beef products considerably in the coming years, which inevitably implies the expansion of grassland systems to areas that were ... -
Quantifying the influence of surface water–groundwater interaction on nutrient flux in a lowland karst catchment
(Copernicus GmbH, 2016-06-01)Nutrient contamination of surface waters and groundwaters is an issue of growing importance as the risks associated with agricultural run-off escalate due to increasing demands on global food production. In this study, the ... -
Sustainable treatment technologies using mixed waste media to mitigate agricultural contaminants in land drainage
(NUI Galway, 2020-01-30)Intensification of agriculture in the European Union has resulted in nutrient losses from farms, which have contributed to a deterioration in water quality. As soil in drainage water ditch networks has limited capacity to ...
