New slurry treatment fixes N from air to create enriched fertiliser
A novel slurry treatment unit that boosts the nitrogen content of liquid manures, using only air and electricity, aims to help farmers reduce reliance on artificial fertiliser, improve crop performance and eliminate methane emissions.
The scalable on-farm technology, developed by Norwegian agritech firm N2 Applied, fixes N from the atmosphere to create a nitrogen-enriched organic fertiliser (NEO).
Through the treatment process, crop-available nitrogen is doubled and nitrogen use efficiency is greatly improved.
Trial results reveal an average yield improvement of 36% and nitrogen uptake improvement of 31% compared with untreated slurry.
