Recycling Nitrogen,
Transforming Farming

Āmua is revolutionizing the agriculture industry with cutting-edge technology that turns cow urine into a powerful, eco-friendly fertilizer. Our innovative cow wearables help farmers maximize profits while reducing their environmental footprint.

Untapped
Nitrogen Potential

Did you know that the average New Zealand dairy cow excretes between $150 to $200 NZD worth of nitrogen each year? Yet, only 5-10% of this nitrogen is currently being utilized to contribute to pasture growth. Unlocking the full potential of this valuable resource could drive both environmental and economic benefits for farmers across the country.

Nitrate leaching

Contaminates waterways

Nitrogen leaching reduces oxygen levels in freshwater (eutrophication). This degrades water quality, disrupts ecosystems, threatening the sustainability of freshwater resources and reducing drinking water quality.

N₂O Emission

A potent greenhouse gas

Nitrous oxide from urine patches contributes approximately 2-3% of New Zealand's total greenhouse gas emissions.

Uneven Growth

Limits pasture production

Currently, up to 4% of dairy pasture is covered by urine patches. Urine patches create nitrogen-rich hotspots, causing excessive growth in these areas while leaving others undernourished.

Uneven patches

Pasture uptakes all the nitrogen it can, while the rest is lost as N₂0 and leached to freshwater.

Our solution

Spread it out

Āmua devices transform farming by increasing the size of urine patches, reducing nitrogen concentration and distributing its benefits across the entire paddock.
