Robert Salmon, a UK-based arable farmer, found that constraining farming machinery to a permanent lane significantly reduced damage to the soil. "Allowing machines unconstrained travel across the land can result in virtually all of the land being run over, which compromises the drainage and friability." In 2016, Robert planned to transition his 4,800 acres to a 12-meter controlled traffic system where all the farm machines will use the same permanent traffic lane. Implementing a controlled traffic system requires accurate techniques, which are almost impossible with traditional GPS systems. RTK technology can provide centimeter-level accuracy, which enables farmers to accurately map their fields and constrain vehicles permanently on the same lane. It transmits the correct positioning information to tractors by radio signal, allowing them to stay on track while moving. This innovation boosts soil health and productivity, increasing output with less input. Summarize
