This experiment developed a robot that could take a soil sample, analyse the nitrate content of the sample onboard the robot and report the result. The mapping software divided the field into sampling areas and chose sampling sites, then mapped the nitrate content found at each site and generalised to the area. A fertilizer schedule was produced to exactly supply the extra nitrogen needed. The system was built to be extendable to simultaneously perform other soil quality tests.

This system will reduce fertilizer use and thereby reduce the environmental damage caused by fertilizer run-off, as well as reducing farmer costs while maintaining productivity.
