The lower tillage intensity in Africa may simply reflect the abundance of land: in order to maximize labor productivity, people work thinly over a large area. Under the substitution view, the profitability of mechanization and its contribution to economic growth depend on the opportunities available to workers (and sometimes draft animals) released from their tasks.

At the beginning of a mechanical spurt, many small firms enter with alternative designs. The most successful either grow or are bought up by larger firms; small producers disappear or revert to servicing machinery.

In the developing countries, the trend towards adoption of the tractor as the fundamental unit of agricultural mechanization systems is sure to continue. However, for many small farmers in deprived regions the transition to tractor-based mechanization is not a realistic option due to the lack of finance and basic infrastructure. In this situation, a continued reliance on human energy and animal-powered equipment for tillage, planting and harvesting will prevail for the foreseeable future.

For smaller, less accessible areas, knapsack sprayers mounted on a persons back and operated by a manually pressurized nozzle are still quite popular and inexpensive. More specialized equipment including high-pressure orchard sprayers, airblast sprayers, electrostatic sprayers, aircraft sprayers and dusters has also been described in Fertilizer Applicators and Plant Protection Equipment (EOLSS on-line, 2002).
