The challenge of the urine patch for managing nitrogen in grazed pasture systems
DR Selbie, LE Buckthought, MA Shepherd - Advances in agronomy, 2015 - Elsevier
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 …
