Appraisal and ranking of poly-aluminium chloride, ferric chloride and alum for the treatment of dairy soiled water
Mohamed, A.Y.A.; Siggins, Alma; Healy, Mark G.; Ó hUallacháin, Daire; Fenton, Owen; Tuohy, Patrick (Elsevier, 2020-04-29)Land spreading of dairy soiled water (DSW) may result in pollution of ground and surface waters. Treatment of DSW through sludge-supernatant separation using chemical coagulants is a potential option to reduce the negative ... -
Assessment of the hydraulic and filter performance of different drainage stone aggregates to elucidate an optimum size range for use in clay-textured soils
Byrne, Ian; Healy, Mark G.; Fenton, Owen; Tuohy, Patrick (Elsevier, 2023-01-18)On poorly drained grassland farms in Ireland, stone aggregates remain the only in-field drain envelope material used by contractors. A variety of aggregate sizes and lithologies are currently in use, but their performance ... -
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 ... -
An integrated connectivity risk ranking for phosphorus and nitrogen along agricultural open ditches to inform targeted and specific mitigation management
Opoku, D. G.; Healy, Mark G.; Fenton, Owen; Daly, K.; Condon, T.; Tuohy, Patrick (Frontiers Media, 2024-02-19)On dairy farms with poorly drained soils and high rainfall, open ditches receive nutrients from different sources along different pathways which are delivered to surface water. Recently, open ditches were ranked in terms ... -
Investigating the suitability of synthetic envelopes as an alternative or complement to stone aggregate in clay-textured soils in Ireland
Byrne, Ian; Healy, Mark G.; Fenton, Owen; Tuohy, Patrick (Elsevier, 2022-12-21)In Ireland, agricultural landscapes dominated by high rainfall and poorly drained soils have high densities of in-field pipe drains surrounded by stone aggregate envelopes. Unlike other countries, there is limited availability ...
