Abstract

Farmers are having to gather increasing amounts of data on their soils and crops. Precision agriculture – the targeting of inputs such as fertilizers and herbicides according to locally determined (‘metre-by-metre’) requirements – is based on a knowledge of the spatial variation of soil and crop parameters across a field. The data has to be spatially located and GPS is an effective way of doing this. A backpack data logging system with GPS position tagging is described which has been designed to aid a fanner in the manual collection of data.
