    The fate of urine nitrogen: A grassland lysimeter study in Ireland 

    Selbie, Diana; Cameron, Keith C.; Di, Hong J.; Moir, James L.; Lanigan, G. J.; Richards, K. G. (Fertilizer and Lime Research Centre, 2014-02)
    In grazed pasture systems, the nitrogen (N) contained in a cattle urine patch may be up to 1200 kg N ha⁻¹. The majority of this N is in excess of plant requirements and is vulnerable to environmental loss. In this study, ...

    Urine patch area coverage of an intensively stocked dairy pasture 

    Moir, James L.; Cameron, Keith C.; Di, Hong J.; Fertsak, Ulrike (International Union of Soil Science, 2010-08)
    The urine patch of the grazing cow has been identified as the key source of N loss from pasture-based dairy systems. Although critical to N modelling, quantitative data on the annual area coverage of urine patches in pastures ...

    Urine patch area coverage of an intensively stocked dairy pasture 

    Moir, James L.; Cameron, Keith C.; Di, Hong J.; Fertsak, Ulrike (Lincoln University., 2010-08)
    The objective of this study was to develop a new method to quantify seasonal and annual urine patch area coverage under an intensive dairy farming system.

    The fate of urine nitrogen with use of a nitrification inhibitor 

    Selbie, Diana; Cameron, Keith C.; Di, Hong J.; Moir, James L.; Lanigan, G. J.; Laughlin, R. J.; Richards, K. G. (2012)
    Pasture-grazed ruminants in Ireland contribute a significant proportion of nitrogen (N) loss to the environment through excreta deposition. Feed N utilisation by the ruminant animal is low with 60-90% of ingested N returned ...
