Recycling Nitrogen,
Transforming Farming

Cows produce a vast natural nitrogen resource—used wisely, it benefits both farms and the environment. Our innovative technology increases farm income while substantially reducing freshwater nitrate leaching and nitrous oxide emissions. Helping farmers to grow more grass and halve fertiliser costs.

Untapped
Nitrogen Potential

Cows generate more nitrogen per year than the total amount of synthetic nitrogen fertiliser imported and applied to farms. For comparison, a cow nitrate patch contains the equivalent of up to 1000 kg N per hectare, while synthetic nitrogen application rates are typically 30-50 kg N per hectare. Making use of this natural nitrogen resource creates a resilient, dependable, on-farm fertiliser supply, keeping farm profits local.

Nitrate leaching

Contaminates freshwater

Nitrate is the world's most widespread freshwater pollutant. Nitrate leaching reduces oxygen levels in freshwater (eutrophication). Threatening drinking water quality, disrupting ecosystems, and affecting the sustainability of freshwater resources. Most freshwater nitrate leaching originates from small, concentrated cow nitrate patches.

Nitrate Oxide Icon-Green-Amua

N2O Emission

A potent greenhouse gas

Nitrous oxide makes up 7% of total global greenhouse gas emissions. Cow nitrate patches from intensive agriculture make up most of these nitrous oxide emissions. Nitrous oxide is a long-lived greenhouse gas, being 300 x more potent than carbon dioxide. Reducing N₂O emissions from intensive agriculture can make a substantial impact on global greenhouse gas levels.

Growth Potential

Use it, don’t lose it

Currently, only 4% of pasture is covered by nitrate patches meaning this nitrogen resource is lost to the environment, only causing problems. Imagine your paddocks, covered with the high pasture growth of these patches. Making use of a resource already on your farm to generate more income.

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.
