Runoff and subsurface drain response from mole and gravel mole drainage across episodic rainfall events
- P. Tuohy, J. Humphreys, N. Holden, O. Fenton
- Environmental Science
- 1 May 2016
Shallow drainage techniques such as mole and gravel mole drainage are used in low permeability soils to siphon off infiltrating rainwater and mitigate the associated rise in watertable. Their purpose… Expand
The effects of treading by two breeds of dairy cow with different live weights on soil physical properties, poaching damage and herbage production on a poorly drained clay-loam soil
- P. Tuohy, O. Fenton, N. Holden, J. Humphreys
- Medicine, Environmental Science
- The Journal of Agricultural Science
- 16 October 2014
SUMMARY There is little empirical evidence to indicate that dairy cow live weight affects the extent of soil damage at the hoof-soil interface during grazing on poorly drained permanent grassland. In… Expand
Influence of artificial drainage system design on the nitrogen attenuation potential of gley soils: Evidence from hydrochemical and isotope studies under field-scale conditions.
- E. Clagnan, S. Thornton, +4 authors O. Fenton
- Environmental Science, Medicine
- Journal of environmental management
- 15 January 2018
In North Atlantic Europe intensive dairy farms have a low nitrogen (N) use efficiency, with high N surpluses often negatively affecting water quality. Low feed input systems on heavy textured soils… Expand
Field soil and ditch sediment phosphorus dynamics from two artificially drained fields on poorly drained soils.
The installation of artificial drains alters soil permeability such that migrating water interacts with soil and sediment biogeochemistry to mobilise or attenuate phosphorus (P). Soil and ditch… Expand
Modeling Performance of a Tile Drainage System Incorporating Mole Drainage
- P. Tuohy, J. O’Loughlin, O. Fenton
- Engineering
- 2018
Mole drain performance is known to vary temporally and spatially due to variations in soil properties, installation conditions, mole channel integrity, and weather patterns. In fine-textured,… Expand
Mixed Agricultural Pollutant Mitigation Using Woodchip/Pea Gravel and Woodchip/Zeolite Permeable Reactive Interceptors
- T. G. Ibrahim, Alexis Goutelle, +6 authors O. Fenton
- Chemistry
- Water, Air, & Soil Pollution
- 24 February 2015
Dairy soiled water (DSW) is water from concreted areas, hard stand areas and holding areas for livestock that has become contaminated by livestock faeces or urine, chemical fertilisers and parlour… Expand
Mole drain performance in a clay loam soil in Ireland
- P. Tuohy, J. Humphreys, N. Holden, O. Fenton
- Environmental Science
- 27 March 2015
There is uncertainty regarding the suitability of some soils for mole drainage. Soils with questionable potential for the formation of stable mole channels generally have <45% clay and >20% sand, and… Expand
An integrated assessment of nitrogen source, transformation and fate within an intensive dairy system to inform management change
- E. Clagnan, S. Thornton, +9 authors O. Fenton
- Environmental Science, Medicine
- PloS one
- 23 July 2019
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… Expand
Greenhouse gas emissions from temperate permanent grassland on clay-loam soil following the installation of artificial drainage
- N. Valbuena-Parralejo, N. Valbuena-Parralejo, +5 authors J. Humphreys
- Environmental Science
- 2019
Abstract Shallow drainage (e.g. mole and gravel mole drainage installed at 0.55 m below soil surface) is used on pasture-based farms to reduce soil moisture, deepen water table depth and thus… Expand
Visual drainage assessment: A standardised visual soil assessment method for use in land drainage design in Ireland
- P. Tuohy, J. Humphreys, N. Holden, J. O’Loughlin, B. Reidy, O. Fenton
- Environmental Science
- 1 June 2016
Abstract The implementation of site-specific land drainage system designs is usually disregarded by landowners in favour of locally established ‘standard practice’ land drainage designs. This is due… Expand
