The fate of urine nitrogen: A grassland lysimeter study in Ireland
(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
(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 ...
Confirmation of co-denitrification in grazed grassland
(Nature Publishing Group, 2015-11-30)
Pasture-based livestock systems are often associated with losses of reactive forms of nitrogen (N) to the environment. Research has focused on losses to air and water due to the health, economic and environmental impacts ...
Urine patch area coverage of an intensively stocked dairy pasture
(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.
Soil inorganic nitrogen in spatially distinct areas within a commercial dairy farm in Canterbury, New Zealand
(New Zealand Grassland Association, 2017)
For precision nitrogen (N) fertilisation of grazed dairy paddocks, soil N distribution needs to be quantified. It is expected that farm infrastructure will affect inorganic-N distribution due to its influence on cow grazing ...
