Shallow (0-30 cm) and deep (0-90 cm) EC readings collected at 3-5 km/h create high-resolution maps of clay content, organic matter, and moisture-holding capacity across field extents that single soil samples cannot capture. EC maps are used as management zone boundaries for composite soil sampling, reducing the number of laboratory samples required while improving the accuracy of nutrient recommendations. Compatible with Ag Leader, Trimble, and John Deere displays via ISOBUS or serial output for seamless integration into existing guidance workflows. GPS accuracy is provided by the tractor’s existing guidance receiver. Veris Surveyor software converts EC data into zone maps and exports shapefiles compatible with all major precision agriculture platforms.
