Abstract
In cultivation trials in the north, the properties of organic fertilizers from biogas plants and other digestate products are being compared to mineral fertilizers. We are investigating whether it is possible to grow spring wheat using different digestate products as fertilizer. The field trials in Umeå, Västerbotten, are part of the Boost Nordic Biogas project, where participants from northern Sweden, Finland, and Norway collaborate to develop biogas production in the region. In the cultivation, pelleted biofertilizer from Alviksgården, recycled ammonium sulfate, and liquid biofertilizer from Härnösand have been used as nitrogen fertilizers. Biochar from sewage sludge and dewatered biofertilizer have been used as phosphorus fertilizers. These types of fertilizers have in turn been compared to both mineral-fertilized and unfertilized controls.
