Increase pasture growth with Virtual Fertiliser™

Every farmer knows how good the grass grows in cow nitrate patches. Imagine this high pasture growth over your whole farm, at half the cost of traditional urea.
Nitrogen produced by livestock - no1's - mimi - pee, used to be a waste product.
Virtual Fertiliser™ applies livestocks nitrogen over the whole paddock.
Increasing pasture growth, halving nitrogen costs and sorting the environmentals.

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.
