To feed a growing population global food production must increase. This leads to more land used for food production, threatening ecosystems and species all over the world.
Organic fertilisers, such as livestock slurry, are used as fertiliser to produce food, but they involve high losses of nutrients and is not sufficient to produce enough food. Chemical fertilisers, produced with fossil fuels, are added to compensate for the losses, and the use of chemical fertilisers, is currently supporting half of the world’s population (Our World in Data). Current practices are costly, has a low resource efficiency and as the lost nutrients ends up as emissions and pollution. Relying solely on chemical fertilisers also damage the soil over time, and getting organic matter back is important to improve soil health. These practices are not sustainable for the planet or for the farmers economy.
The shift to a more sustainable and circular food production is essential. The challenge is to feed more people without using more land, while reducing emissions. Thus, there is a need for solutions that provide a holistic approach that stop nutrient losses, utilise local renewable resources and reduces emissions
