The object of the present invention is to create a biological composting method for the manufacture of a natural fertilizer, enriched soil or the like, in which process the pH value is lowered in a natural way, and where manure or residue from a biogas installation is used as a major component in the natural fertilizer product. The biological composting method provides a product in which the ammonia content is maintained, malodorous substances are converted, and vital nutrients both micronutrients and, in particular, macronutrient are conserved such that a substantial odour free and a stable natural fertilizer product is obtained. |
