Optimisation of Sustainable Biomass Supply from Representative Permanent Grassland Sits of Germany for Biogas Production

F. Schmidt, K. Gödeke & H. Hochberg
The project ‘GNUT-Biogas' (2010 -2013) will provide urgently needed knowledge required to make the energetic potential of permanent grassland accessible and consequently contribute to the preservation of permanent grassland areas.
