ABSTRACT
Precision farming incorporates the key elements of geo-technology (one of the mega-technologies of the twenty-first century) in an integrated farm-management programme. Key components of geo-technology include global positioning systems (GPS), geographical information systems (GIS), remote sensing data, data-collection devices and variable-rate controllers or robotics. Remote sensing (data and data-collection devices) provides elements critical to the success of the technology-rich management system. The information derived is analysed in a systems approach and used to provide economic sustainability for the production of food and fibre while preserving the environment.
