ABSTRACT
New technological developments such as precision agriculture have revolutionized the traditional approach of farming. Precision agriculture provides highly sophisticated information to assist farmers/managers in their normal, everyday planning and strategic decisions, which can expand farmers’ management capacity and management time. Used efficiently and correctly, precision agricultural techniques and site-specific management can assist the farm manager in identifying opportunities to optimize input applications, cut input costs, increase production, reduce production risks, and promote greater profitability within the strategic plan of the farming business (Nell and Napier, 2005). Precision agriculture in this chapter refers to the management of variability by means of Geographic Positioning Systems (GPS), and site-specific management refers to the management of variability without using GPS-based systems.
