Ruminants excrete as much as 70–95% of the nitrogen (N) they consume. The urine patch is
the conduit through which much of this N is recycled in grazed pasture systems. This chapter …

Pastoral systems are characterised by a number of features that are absent in arable
cropping systems. These features include:(i) pastures are biologically diverse so interactions …

Nitrogen (N) leached into groundwater from urine patches of cattle grazing in situ is an
environmental problem in pasture-based dairy industries. One potential mitigation is to …

There is an increasing pressure on temperate pastoral dairy production systems to reduce
environmental impacts, coming from the inefficient use of N by cows in the form of excessive …

Simple Summary We studied the nitrogen excretion patterns of cows selected for divergent
nitrogen excretion consuming either ryegrass or plantain. Both the use of a plantain diet as …

The largest contributor to nitrogen (N) leaching from ryegrass-clover pasture based dairy
farms is the surplus feed N excreted as urinary N (UN) onto pastures. Pastures consisting of …

Nitrogen (N) fertiliser is applied to pastures in dairy farming systems to ensure productivity,
but it is an expensive input that could be damaging to the environment if used excessively. In …

Farmers face complex decisions at the time to feed animals, trying to achieve production
goals while contemplating social and environmental constraints. Our purpose was to …

A 3-year study was carried out in Canterbury, New Zealand, to determine the effect of a
nitrification inhibitor dicyandiamide (DCD) on N2O emissions, nitrate () leaching and pasture …

Precision livestock farming (PLF) offers a strategic solution to enhance the management
capacity of large animal groups, while simultaneously improving profitability, efficiency, and …
