Ignoring the inherited spatial variation in soil properties with traditional sampling methods leads to poor crop management, yield loss and excess use of input. The proposed system of FarmFuse addresses these issues in 2 ways: (a) utilising a new and innovative on-line multi-sensor platform for measuring key soil properties at an appropriate resolution. (b) Integrating this improved soil data with other information such as vehicle-borne sensing of crop growth, weather data, soil conductivity and yield maps, to develop algorithms to determine rules for variable rate application. These can then be integrated into FMIS. The vision for the final integrated system would be a server that would allow the end user to access and upload data including maps of soil, crop and yield in addition to recommendations about site specific applications. The resultant treatment maps would then be uploaded to precision agriculture compatible implements for site specific application of inputs.
