Our mission is to solve the global nitrate problem for agriculture and our environment.

Āmua is a team passionate about making practical environmental change. We develop solutions where environmental benefits also improve farm profits. Our vision is for pasture-based agriculture to lead natural food production & improve our planet’s environment.

Roger Johnson

Farming in the Amuri Basin, with New Zealand’s highest producing dairy farms on our doorstep, we saw the potential of nitrogen produced by cows. The problem is there’s so much nitrogen in each small nitrate patch that grass can’t use it all.

We thought, if we could harness the nutrient in nitrate patches to cover the whole paddock, we could grow more grass instead of it leaching through the soil, into freshwater. 

We wouldn’t need to import all of this expensive synthetic urea. This would save farmers a lot of money and prevent the environmental problems caused by small nitrate patches. Our life’s work is focused on solving the global nitrate problem.

Thomas Ponter-Amor

Inspired by New Zealand’s rich tradition of engineering innovation, Thomas recognized the untapped potential where technology meets agriculture. As a Mechatronics Engineer from the University of Canterbury, he has contributed to pioneering electronic consumer vehicles with local Kiwi companies. Now, he is applying his expertise to a mission with far greater impact.

Agriculture is essential to feeding the world, yet its environmental footprint often remains a significant challenge. Inefficient systems waste valuable resources and harm ecosystems. Thomas is committed to changing this, believing that smarter technology holds the key. With a deep passion for embedded systems, he is focused on designing tools that not only enhance farm efficiency but also reduce environmental impact.
