Abstract: The soil fertilized with biogas residues showed a lower affinity for carbon losses in the form of CO2 after tillage than the mineral fertilised and unamended treatments. However, high biogas residue concentrations in the soil seem to level off reduced NH3 losses by injection due to increased emissions of N2O, N2 – and presumably – NO.

Der mit Gärrest gedüngte Boden zeigte eine geringere Affinität für Kohlestoffverluste in Form von CO2 nach Bodenbearbeitung als die mineralisch gedüngte und die ungedüngte Varianten. Jedoch scheinen hohe Gärrestkonzentrationen im Boden die durch Injektion reduzierten NH3-Verluste durch erhöhte Emissionen von N2O, N2 – und vermutlich NO – zu nivellieren. [German]
