• Effect of anaerobic digestion of manure before application to soil – benefits for nitrogen utilisation? 

      Føreid, Bente; Szocs, Julia Maria; Patinvoh, Regina J.; Horváth, Ilona Sárvári (Peer reviewed; Journal article, 2021-03-03)
      Purpose Anaerobic digestion produces renewable energy, biogas, from organic residues, but also digestate, a valuable organic fertiliser. Previous studies have indicated that digestate contains ample plant available nitrogen ...
    • Greenhouse gas emissions from digestate in soil 

      Dietrich, Maria; Fongen, Monica; Føreid, Bente (Peer reviewed; Journal article, 2020-03-11)
      Purpose Biogas residues, digestates, contain valuable nutrients and are therefore suitable as agricultural fertilizers. However, the application of fertilizers, including digestates, can enhance greenhouse gas (GHG) ...
    • Recycling of biogas digestates in plant production: NPK fertilizer value and risk of leaching 

      Sogn, Trine Aulstad; Dragicevic, Ivan; Linjordet, Roar; Krogstad, Tore; Eijsink, Vincent; Eich-Greatorex, Susanne (Journal article; Peer reviewed, 2018-01-08)
      Purpose The main purposes of the study were to assess the NPK fertilizer value of biogas digestates in different soils and to evaluate the risk of unwanted nutrient leaching. Methods The fertilizer value of digestates from ...
