Dear Bennet, one of the reasons of applying organic manures to the soil is to provide the micro-organisms in the soil with nutrition. There are many reduced organic compounds in the material coming out of the biogas plant. The soil micro-organisms can gain metabolic energy by oxidising them. If you aerobically composted them, this advantage is lost. Yours A.D.Karve
