In watching television or other films regarding agriculture in various nations, one can occasionally still see where horses, mules, donkeys, or oxen are used to plow/plough fields or haul produce from farm to market. These practices seem antiquated by today’s farming techniques which mostly employ large combustion engine combines or tractors, trucks, etc. Much has been written about the agricultural revolution that occurred throughout most developed nations between the world wars and especially after the second one in which the use of more and more machinery has been used to grow agricultural produce such as wheat, corn, barley, etc. Even in the developing countries, more and more machinery is being used in agricultural production.
