The emphasis on shifts in power sources, especially the shift to tractors, can cause misunderstandings about which operations are the most likely candidates for mechanization in developing countries. This section therefore discusses mechanization in terms of operations and pays only occasional attention to power sources.
Milling, threshing, chopping, sugarcane crushing, pumping of water, and the like are extremely power-intensive but need little control. Moreover, both stationary and mobile sources of power can be used for them.

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.
These renewable sources are normally processed off-farm and sold nationally or regionally and, as such, are not considered as a local autonomous power supply for agriculture. In the future, it is likely that the diesel oil supply will dwindle and may eventually run out. As such, governments and appropriate agencies may wish to encourage the development of an infrastructure for processing and distribution of diesel fuel alternatives to cope with such a scenario.
