Apparent soil electrical conductivity (ECa) is typically mapped to define soil spatial variability within an agricultural field. Knowledge of the vertical variability of ECa is desired to define the site‐specific behavior of the soil profile. A pneumatic angular scanning system (PASS) was developed to sense horizontal and vertical changes of ECa on‐the‐go with an electromagnetic induction (EMI) instrument using an angular scanning method. This sensor system consists of a sled with a rotating mechanism, an EMI sensor, an inclinometer, and a pneumatic actuator. The system was evaluated at the University of Nebraska‐Lincoln Agricultural Research and Development …
