Forage Legumes for Grazing and Conserving in Ruminant Production Systems
As a plant group, forage legumes present some unique advantages and disadvantages for ruminant production. When compared to grasses or cereals their main advantages are generally (i) low reliance onExpand

An appraisal of carbon footprint of milk from commercial grass-based dairy farms in Ireland according to a certified life cycle assessment methodology
PurposeLife cycle assessment (LCA) studies of carbon footprint (CF) of milk from grass-based farms are usually limited to small numbers of farms (<30) and rarely certified to international standards,Expand

Farm-gate nitrogen balances on intensive dairy farms in the south west of Ireland
Nitrogen management and farm-gate N balances were evaluated on 21 intensive dairy farms in the south west of Ireland for each of four years (2003 to 2006). The mean annual stocking density wasExpand

Interannual variation in nitrous oxide emissions from perennial ryegrass/white clover grassland used for dairy production
Nitrous oxide (N2O) emissions are subject to intra- and interannual variation due to changes in weather and management. This creates significant uncertainties when quantifying estimates of annual N2OExpand

An evaluation of life cycle assessment of European milk production.
Life cycle assessment (LCA) is a method regulated by ISO that conveys the environmental impact of products. LCA studies of the same product should be comparable to benefit environmental policyExpand

Nitrogen flows and balances in four grassland‐based systems of dairy production on a clay‐loam soil in a moist temperate climate
This study examined productivity, nitrogen (N) flows and N balances in grassland-based systems of dairy production in Ireland. There were four stocking densities of dairy cows on grass/white cloverExpand

Groundwater: A pathway for terrestrial C and N losses and indirect greenhouse gas emissions
Abstract Estimating losses of dissolved carbon (C) and nitrogen (N) via groundwater in an agricultural system provides insights into reducing uncertainties in the terrestrial C and N balances. InExpand

Comparison of milk production from clover-based and fertilizer-N-based grassland on a clay-loam soil under moist temperate climatic conditions.
This study, conducted over four years (2003-2006), compared herbage production, nutritive value of herbage, the length of the grazing season and milk production per cow and per hectare from grasslandExpand
