Agricultural mechanization has involved the partial or full replacement of human energy and animal-powered equipment (e.g. plows, seeders and harvesters) by engine-driven equipment. Most of this is tractor driven and to a lesser extent self-propelled equipment (including harvesters, sprayers, fertilizer applicators, planters and seeders). Agricultural mechanization has been pioneered in North America and Europe and more recently in Japan, and is now spreading rapidly throughout the world. Notwithstanding such progress, a significant element of human and animal powered mechanization remains, particularly in the poorer regions of the world.
All of the foregoing technological advances have been critically dependent on the availability of an abundant and economic supply of fossil fuels including diesel fuel for on-farm tractors and self-propelled machines; and natural gas, heavy fuel oil and coal for off-farm electricity generation.
