Purpose This study aimed to investigate the efect of time interval between sowing and amendment with non-digested and digested poultry manure and their combinations with urea on the germination of three wheat cultivars (Slambo, Acsad, and Karim) in the desert soil. Methods The cultivars were sown on four diferent dates, i.e. directly, 10, 20 and […]
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) emissions. In this study different processes and post-treatments of digestates were analyzed with respect to triggered GHG emissions in soil. Methods In an incubation experiment, GHG emissions from two […]
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 (N), but there are also concerns about greenhouse gas (GHG) emissions after application of digestates to soil. The aim of this study was to compare digestate and […]
