This paper will focus on grass-clover leys for biogas-based electricity and rapeseed oil as replacement for tractor diesel.
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.
