New Zealand farmer-led startup developing cow wearable technology to reduce nitrous oxide emissions.
The technology enables the rich nitrogen in cow urine to be used as fertiliser - potentially solving freshwater nitrate leaching and nitrous oxide emissions at their source.
By spreading the concentrated urine patches out across the paddock, data modelling by AgResearch in the Bioeconomy Science Institute (BSI), has indicated the patented device could provide comparable pasture growth to synthetic nitrogen, reduce nitrous oxide emissions by up to 95% and nitrate leaching by up to 93%.
Āmua is working on a minimum viable product for pilot trials in 2026.
