Examples include herbicide application based on sensed soil organic matter content, and anhydrous ammonia application in growing maize based on sensed soil nitrate level. This is a complex technology that requires a major investment in research and development. The pay-off will derive from the savings accrued due to lower use of expensive agrochemicals, environmental protection and sustainability.
Mechanization is most profitable and contributes most to growth where land is abundant, where labor is scarce relative to land, and where labor is moving rapidly off the land. Several cases, listed in table 4, illustrate the effects of mechanization on employment.
