The enterprise combination for a marginal farmer under low risk levels was crop (0.25 ha), dairy (1 unit), fishery (0.25 ha) and biogas (1 unit). The authors recommended that biogas be used for electricity production instead. Contrary to the rapeseed oil this energy was not produced nor used on the farm, but farm scale biogas production is a possibility18. Each family requires a single biogas plant, but large farmers can accommodate more units. Animals also contributed significantly to an improvement in soil fertility through manure and biogas production was able to replace domestic fuel needs. Popularization of biogas is slow and caters mainly for heating (cooking, boiling, etc). The solid component is used for biogas production. The biogas would then have been passed through a specially developed tubular solid oxide fuel cell that generates electricity directly. The fertilizing effect of compost and biogas residues from source separated household waste. Producing and using biogas for traction would require unrealistically large, high-pressure storage facilities on the farm to meet peak season demand. Therefore, only slight variations were expected in the digested slurry and in the two fractions produced by separation immediately after the digested slurry leaves the biogas plant. Animal slurry is anaerobically digested in biogas plants with the purpose of producing energy. Biogas fermentation residue was the only soil amendment and the crops planted were alternated every year since 2002. However, at the highest risk level, the enterprise allocations were crop (0.75 ha), dairy (1 unit), fishery (0.25 ha), mushroom (0.72 units), apiary (2 units) and biogas (1 unit).
