Low-temperature hay biochar and acid treatment increases fertiliser value of slurry digestate

Low-temperature hay biochar and acid treatment increases fertiliser value of slurry digestate

This study aimed to evaluate the effect of low-temperature-produced (torrefied at 300°C) hay biochar (BC) on the fertilisation effectiveness of digestate (SD) and the loss of nitrogen (N) and carbon (C). We also examined whether acidification could increase the effect of BC on SD effectiveness and c...
