It's a wee issue but with a big environmental impact - nitrogen released in the urine of cattle affects nearby water quality, and leads to emissions of nitrous oxide, a potent greenhouse gas.
Luckily there's a new award-winning technology here, The Cattle Urine Sensor, to tackle the problem.
It's developed by AgResearch, who's team recently won the Science and Technology Award at the 2023 Kudos Awards in Hamilton.
