Urination data for Welsh Mountain ewes grazing upland and lowland pastures in North Wales, 2016

The data contains urination metrics including frequency, volume, chemical composition, estimated urine patch N loading rates and metabolomics profile of individual urine events from sheep (Welsh Mountain ewe) grazing a semi-improved upland pasture and a lowland improved pasture located in North Wales, UK. Urine collection studies were run in the spring, summer and autumn of 2016 for the semi-improved site and in autumn of 2016 on the lowland improved pasture. Sheep were housed in urine collection pens and while in the pens, each individual urine event was collected and stored separately. The study was conducted as a wider part of the NERC funded Uplands-N2O project (Grant No: NE/M015351/1). The frequency, volume and chemical composition of individual urine events has implications for nitrogen losses from the grazed pasture ecosystem, including emissions of the powerful greenhouse gas, nitrous oxide, and nitrate leaching.

本数据集包含羊（威尔士高山羊）在北威尔士半改良型高原草地和低地改良型草地放牧期间尿液排泄的指标，包括排泄频率、体积、化学成分、估计尿液斑N负荷率和单个尿液事件的代谢组学特征。尿液收集研究于2016年春季、夏季和秋季在半改良型草地进行，在低地改良型草地于2016年秋季进行。单个尿液事件的频率、体积和化学成分对放牧草地生态系统的氮素损失具有重要意义，包括强效温室气体一氧化二氮的排放和硝酸盐淋溶。本研究是NERC资助的Uplands-N2O项目（资助编号：NE/M015351/1）的更大范围研究的一部分。关于本数据集的详细信息，请访问https://doi.org/10.5285/385ec5ab-0c47-46fc-b5df-008ca024296f。
