Precision farming applications promise to conserve energy and reduce agricultural inputs but much remains to be done before these claims can be sustained and the technology commercialized at an affordable price to the farmer. Further exciting developments in farm machinery are under way with particular emphasis on communications and information technology applications.

Early tractor designs were based on the concept of substituting mechanical pulling or draft power for the draft animal classically associated with pulling plows through the soil, operating reaper and binder machines through fields of corn, or mowers through fields of grass. Cumbersome steam powered engines were soon to be replaced by the more energy efficient and compact internal combustion engine.

Early methods of weed control included mowing, flooding, cultivating, smothering, burning, and crop rotation. Though these methods are still important, other means are perhaps more typical today, particularly the use of herbicide (plant-killing) chemicals. Another technique is to introduce insects that attack only the unwanted plant and destroy it while leaving the crop plants unharmed.
The historical image of farm labor has been that associated with backbreaking work, long hours and low pay. From the earliest times attempts have been made to alleviate drudgery through inventions and developments of implements and machines that have gradually transformed agriculture into a modern industry served by technologically sophisticated mechanization systems.In North America and Europe, the combination of advanced mechanization systems, agrochemical inputs and plant breeding has produced an increase in farm production of such proportions that ultimately quotas on production had to be imposed to prevent the accumulation of massive food surpluses. The lesson from this experience is abundantly clear.
