Fig. 3From: The effect of digestate and mineral fertilisation of cocksfoot grass on greenhouse gas emissions in a cocksfoot-based biogas production systemBiomass yield and biogas production (energy potential, with standard error) of unfertilised cocksfoot and cocksfoot fertilised with nitrogen (N) as mineral fertiliser and as digestate. The energy potential is energy that can be produced from the amount of cocksfoot biomass in mono-feedstock biogas productionBack to article page
