Evaluating intermediate crops for biogas production – Effects of nitrogen fertilization and harvest timing on biomass yield, methane output and economic viability
Intermediate crops (ICs) are grown on large areas in Sweden and elsewhere for their function as cover or catch crops and to increase soil fertility, and they are usually soil-incorporated. The aim of this study was to investigate if aboveground biomass from ICs can be a sustainable source of biofuel feedstock. For that, the biomass yield of fertilized and unfertilized ICs was studied in field expe
