AgTech Services' Clay Depth Mapping services allow growers to delve and clay spread with confidence. Using EM38 and ground truthing, we can accurately build clay depth maps, so the grower knows how deep the clay is and if it is at a reachable depth to delve. We can also have the clay analysed for any toxicities before you bring it to the surface. The map below shows a fields clay depth in cm, the red areas being the deeper clay and the blue being surface clay.
