By common consent, diesel oil (used to power the compression ignition engines, so dominant in agriculture) is a nonrenewable resource. Attempts to find or identify a diesel fuel substitute that could be used in conventional diesel engines have made some progress. In particular, the use of oils from renewable oilseeds has enjoyed some limited success in countries such as Austria, where generous tax remission is allowable on a fuel that is otherwise uneconomic.
While much remains to be done on small farms in the poorest regions, sufficient progress has been made to accelerate food production in line with population growth (contrary to the Malthusian prediction). In this theme, farm machinery is considered with primary emphasis on engine and motor driven machines and implements and a lesser emphasis on human or animal powered equipment.
