Developing and validating a decision support tool for media selection to mitigate drainage waters
Ezzati, Golnaz; Healy, Mark G.; Christianson, Laura E.; Feyereisen, Gary; Thornton, Steven; Daly, Karen; Fenton, Owen (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 ... -
Impact of P inputs on source-sink P dynamics of sediment along an agricultural ditch network
Ezzati, Golnaz; Fenton, Owen; Healy, Mark G.; Christianson, Laura E.; Feyereisen, Gary; Thornton, S. F.; Chen, Qing; Fan, Bingqian; Ding, J.; Daly, Karen (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 ... -
An integrated assessment of nitrogen source, transformation and fate within an intensive dairy system to inform management change.
Clagnan, Elisa; Thornton, Steven F.; Rolfe, Stephen A.; Wells, Naomi S.; Knoeller, Kay; Murphy, John; Tuohy, Patrick; Daly, Karen; Healy, Mark G.; Ezzati, Golnaz; von Chamier, Julia; Fenton, Owen (Public Library of Science, 2019-07-23)From an environmental perspective optimised dairy systems, which follow current regulations, still have low nitrogen (N) use efficiency, high N surplus (kg N ha-1) and enable ad-hoc delivery of direct and indirect reactive ... -
Use of rapid small-scale column tests for simultaneous prediction of phosphorus and nitrogen retention in large-scale filters
Ezzati, Golnaz; Healy, Mark G.; Christianson, Laura E.; Fenton, Owen; Feyereisen, Gary; Thornton, Steven; Callery, Oisín (Elsevier, 2020-07-01)Rapid small-scale column tests (RSSCTs) have been previously used to predict the effluent concentration of a single nutrient in large filters with good accuracy. However, in drainage waters originating from heavy textured ...
