Precision farming is expected to become much more widespread in the twenty-first century, symbolizing a better balance between reliance on traditional knowledge, information management and intensive technologies. Five main areas or categories are important: the role of computers, global positioning systems (GPS), geographical information systems (GIS), remote sensing and application control. This paper reviews each of these in the context of Indian agriculture, and confirms that precision farming has the potential to reduce overapplication of agricultural inputs, optimize financial performance and enhance agricultural production.
