Image Number D721-1 Two commercial soil electrical conductivity (EC) sensors were used to map soil variability and develop productivity zones. One is mounted on the back of the tractor and uses disk coulters contacting the soil to measure EC at two depths. The other, attached to the small vehicle behind the tractor, does not require soil contact but measures EC at only one depth.
