Frequently Asked Questions About Precision Farming
RTK (Real-Time Kinematic) is a GPS correction technology that enhances satellite positioning accuracy from metres to centimetres. TAG’s RTK network delivers ±2.5cm pass-to-pass accuracy, enabling precise controlled traffic farming, accurate seed and fertiliser placement, and repeatable tramlines year after year.
Yes. Our RTK base station network is compatible with any M-RTK equipped guidance system, including machines from Case IH, New Holland, Fendt, Massey Ferguson, and other manufacturers. You don’t need to be a John Deere customer to benefit from our correction signal.
The HarvestLab 3000 is a near-infrared (NIR) sensor that provides real-time analysis of crop and organic material constituents. For arable farmers, it measures grain moisture and protein at harvest. For livestock farmers, it analyses forage dry matter and silage quality. For slurry spreading, it measures nutrient content in real time for NVZ-compliant variable rate application.
CultiWise uses AI-powered multispectral drone and satellite imagery to analyse crop health and generate variable rate prescription maps. Instead of blanket-applying seed, fertiliser, or chemicals at a uniform rate, you apply inputs only where they’re needed — typically reducing chemical costs by 15–20% while maintaining or improving yields.
In most cases, yes. John Deere AutoTrac and StarFire receivers can be fitted to a wide range of existing John Deere tractors and combines. For non-JD machines, our RTK correction signal works with third-party guidance systems. Contact TAG Tech to discuss your specific machine and requirements.
TAG’s RTK network covers the West Midlands, Herefordshire, Worcestershire, Shropshire, the Cotswolds, Welsh Borders, Pembrokeshire, Carmarthenshire, and South West Wales. Coverage is expanding — contact us to check signal availability at your location.
