Tractor data: free and for nothing The more data you have, the more reliable the information generally is, and this is certainly the case if you work in precision agriculture


and you are gathering or you need site and time specific information. This often starts with yield mapping in order to understand what yields (and income) your harvests bring


“Dataset more accurate every time”


Dutch arable farmer Chris van de Lindeloof first became interested in collecting tractor data in 2015. “I heard a professor explaining the (future) value of big data, and the extent to which it is already being drawn from the CAN bus in trucks. It got me thinking, so to- gether with my tractor dealer I began look- ing for a solution for our tractors.” Chris con- nected his GPS to the AFS terminal of his Case IH tractor to enable the NMEA signal to be linked to the tractor data. Since then, a vast amount of data is being recorded site specific, alongside GPS data such as height and position. “We collect eight types, and the most interesting are fuel economy and height when working the soil. Fuel efficien- cy relates directly to the structure and con-


dition of the soil. This is of particular interest to us because our fields have widely varied soil types.”


Chris sees clear correspondence between sat- ellite images and the soil data based on fuel economy during ploughing and power har- rowing. “You can easily distinguish the tram- lines, and for several seasons now, I have suc- cessfully used it to make application maps for variable rate application of herbicides, drilling wheat, and spreading fertilisers. I know that you can collect even more data from soil scan- ners, such as the pH, but the data I collect is free of charge. Plus, because I collect data every time I cultivate, it doesn’t produce a mere snapshot with a single plot map. This in- creases the reliability of my data set each time.”
