Technological advances are giving growers a valuable boost in their ongoing efforts to generate more value from existing resources. In recent years, attention is increasingly turning to the opportunities offered using new information technologies in agriculture, called Precision Agriculture. Although Precision Agriculture offers new technologies and methodologies for growers to better use resources, it is not a reinvention of the wheel. Precision Agriculture is still based upon long-standing horticultural principles which are used to varying degrees by Australian growers. It uses a combination of new technology and existing agronomic knowledge to maximise farm efficiency.
