Enabling farmers to produce their own fertiliser

N2 Applied has created a closed-cycle, on-farm system for producing nitrogen fertiliser. It lets farmers produce high-quality fertiliser using locally sourced manure and renewable energy.


More than 22 million metric tons of ammonia are lost from livestock farms around the world every year. The ammonia is created from nitrogen in animal waste and leaks into the air or ground.

Ammonia can be an important source of nutrients for growing crops, but when released into the air, it can react with other gases and create harmful emissions.

Without a way of capturing ammonia, farmers may have to purchase industrial nitrogen fertiliser, which is costly and often produced with fossil fuels. If kept on the farm, however, the ammonia can be an essential ingredient in sustainable farming practices.

Circular economy

N2 Applied has developed a technology to produce nitrogen fertiliser on a farm, through fixing nitrogen from air and reacting it with ammonia in manure or biogas digestate.

This chemical reaction stops ammonia from escaping and increases the nitrogen content in the manure or digestate. The reaction also removes the odour from the nitrogen-enriched fertiliser.

N2 Applied’s technology enables livestock farmers to recycle nitrogen and produce their own fertiliser with low greenhouse gas emissions, improved resource efficiency and reduced costs.

The farmer can use the farm-made fertiliser to complement and eventually substitute traditional fossil fuel-based industrial fertiliser. N2 Applied thus disrupts the fertiliser value chain, changing it from a linear to a circular model.

Concrete benefits

N2 Applied’s solution provides farmers with cost-effective, high-quality fertiliser, which improves nitrogen use efficiency and increases crop yield, creating extra revenue for the farm. The production system is no larger than a standard refrigerator and can be powered by local, renewable energy.

On-farm fertiliser production improves the carbon footprint of a farm and its entire supply chain. Reducing ammonia emissions ensures business continuity in locations where stricter regulations are being implemented to reduce greenhouse gas emissions, local pollution and odour problems.

Market potential

There are a number of macro trends in renewable energy and sustainable agriculture that are creating favourable framework conditions for N2 Applied’s technology. Countries are, for example, introducing incentives to accelerate the transition to greener agriculture, and taxes or limits on carbon and ammonia emissions are being discussed.

Large, professional farms in northwestern Europe and South Africa are among N2 Applied’s target markets. Here, interest in and knowledge of how to take advantage of new technology is high. N2’s early market development focuses on demonstration and verification of the working principles under local farm conditions in markets including Denmark, Northern Ireland and the Western Cape province in South Africa.
