In 2020, N2 Applied developed a mineral fertiliser project tailored for horticulture together with Snarum Gartneri (Snarum Horticulture). The 2-year project was supported by the GRO-Fund and demonstrated it was possible to substitute fossil fuel based chemical fertilisers with recycled nutrients by utilising N2`s plasma treatment process. 

The reuse and recovery of waste streams of nutrients was central to this project. Minerals such as calcium, magnesium or phosphorus were liberated from waste streams of dolomite and struvite. Plasma-generated nitrate was utilised to dissolve waste streams into a complete mineral fertiliser. Where it was not possible to get the desired concentration of a nutrient from a waste source, certified organic sources were used instead, making the fertiliser solution delivered to plants fully sourced from waste streams, organic sources or the air.  

The fertiliser was used in multiple growth cycles at Snarum Gartneri, where it demonstrated that its use, produced plants of equal quality to the commercial counterpart, in terms of growth rate, flavour, smell and storage ability. The fertiliser was also released as a take-home version and was very popular among hobby-growers.
