The loss of nitrogen (N) through nitrate (NO₃⁻) leaching and nitrous oxide (N₂O) emissions from pastoral dairy systems is one of the largest challenges facing the New Zealand agricultural industry. Nitrate leaching ...

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 ...

Nitrogen (N) cycling and losses in grazed grassland are strongly driven by urine N deposition by grazing ruminants. The objective of this study was to quantify pasture N concentrations, yield and N uptake following autumn ...

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.
