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, ...
