This paper provides an overview of precision farming technologies that are entering the market place. It is probable that the technology will continue to develop and that its adoption in agriculture will grow. Precision farming products and services are being commercialized for cotton. Because soils are more fixed than are pest populations, precision-farming technology has been applied to sampling soils and managing plant nutrition before its application to other crop inputs, such as pest management. The factor that will determine the extent of the adoption of precision farming technology in cotton and agriculture generally, will be its net economic impact on growers.
