Assessment of materials used in land drainage systems
Byrne, Ian Richard (NUI Galway, 2023-08-15)Agricultural land drainage is one of a number of critical components to sustaining food production on poorly drained mineral soils. The key to efficient and consistent drainage system performance is an appropriate type and ... -
Assessment of the impact of forestry on peatlands on the environment
Finnegan, Joanne (2012-12-19)Ireland's forest cover stands at approximately 10 %, or 700,000 ha, of the total surface area of the island and it is estimated that almost 60 % of this forestry is on peat. Forestry on peatland throughout the world is now ... -
Chemical Amendment of Dairy Slurry For The Control of Phosphorus in Runoff From Grassland
Brennan, Raymond B. (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 ... -
Combined zeolite and chemical amendments mixed with agricultural wastes to reduce surface and leaching losses of nutrients and greenhouse gas emissions, and biofilter treatment of dairy soiled water
Murnane, John G. (2017-05-08)Agricultural activity is a major source of nutrient emissions to surface and ground waters and a significant contributor to greenhouse gas emissions. Despite legislation to improve terrestrial water quality, prescribed ... -
Cycling and transport of phosphorus and nitrogen from harvested peatland forests and possible mitigation and methods
Asam, Zaki-Ul-Zaman (2012-11-16)Drainage of peatlands has been part of forestry practice since the early 20th century. In Ireland and the UK, approximately 800,000 ha of peat catchments were drained and afforested between the 1950s and 1990s. A large ... -
Development of filtration technologies for effective, cost-efficient and robust water treatment
Grace, Maebh A. (2016-08-12)The provision of high quality, potable water in a sustainable and effective manner is a key challenge for water engineers, scientists, and policy makers. Urbanisation and industrial development, along with population ... -
The erodibility and phosphorus loss potential of a selection of Irish tillage soils
Regan, John T. (2012-08-17)Arable cropping, due to its intensive nature, can leave soil with reduced ground cover and impaired soil structure, making it vulnerable to erosion under heavy rainfall. Runoff containing suspended sediment (SS) and ... -
The impact of chemically amended pig slurry on surface runoff, leachate and greenhouse gasses.
O' Flynn, Cornelius J. (2013-08-27)In Ireland, the pig industry is concentrated in a small number of counties. Pig farms typically have a high stocking rate. Therefore, the disposal of slurry in a cost-effective and environmentally-responsible way is a ... -
Mineral fertiliser equivalence value of dairy processing waste and derived strubias products
Shi, Wenxuan (NUI Galway, 2023-03-09)Globally, agriculture urgently needs alternative sources of phosphorus (P). Presently, global agriculture is over-reliant on inorganic mineral P fertilisers sourced from finite mining sources. This is especially relevant ... -
Optimizing dairy farmyard infrastructure for the management and treatment of dairy soiled water
Abdalla Mohamed, Ahmed Yousif (NUI Galway, 2023-01-20)Dairy farms produce dairy soiled water (DSW) during the milking process, which consists of a mixture of water, cow faeces, urine, milk, detergents, and sediment. Land spreading is the most common disposal method for ... -
Pesticide management for better water quality
McGinley, John (NUI Galway, 2023-07-31)The growth of the global population has forced the intensification of agricultural practices in order to achieve increased crop yields and production rates. This has been accomplished by elevated pesticide usage. While ... -
A toolkit for assessing unsaturated soil time lag with respect to Water Framework Directive deadlines
Vero, Sara (2016-02-09)Time lag is the delay between the implementation of water quality mitigation measures and observed effects on water quality. This delay arises as a result of the long hydrological/hydrogeological pathways between nutrient ... -
Treatment of dairy soiled water using an aerobic woodchip filter and a sand filter
Ruane, Eimear M (2012-05-04)The milking process produces dairy soiled water (DSW) that contains variable concentrations of nutrients. The most common method of disposal is by application to land. However, this practice can result in the pollution ... -
Treatment options for the separated solid fraction of pig manure
Troy, Shane (2012-09-20)Landspreading of pig manure in quantities greater than that required by plants can result in pollution of ground and surface water bodies. Recent regulations have placed restrictions on the application of manure to land, ...
