Place the rectangular sensor with the long cable on the tree, ensuring the spike points toward the roots. Connect the BNC connector to the black amplifier box. Attach the soil sensor (cylindrical) to the amplifier box. Secure a loose rope around the tree to maintain a consistent distance between the tree and the soil sensor. Proceed to move the soil sensor in small steps around the tree, ensuring the rope stays taut. Take measurements at each sensor position.
