? 2022 Elsevier LtdAcquiring soil moisture content (SMC) in a mobile way when opening furrows during planting can improve the timeliness of the information to help make planting decision. Common commercial TDR SMC probe sensors was used to discuss the feasibility of applying probe sensors on on-the-go SMC measurement. And a revolving test bench with regulated speed was used to repeatedly conduct dynamic test. The dynamic test results showed common probe sensors can be used for mobile SMC measurement. The optimal measuring attitude of the probe sensor was that the front side of the probe sensor was vertical to soil surface and the probes inclined from the side view (FVSI). When the travel speed was not over 4.8 km/h, the dynamic measured and the static measured after the dynamic test by FVSI owned good correlation. In addition, the movement of the rods of the sensor had relatively stable influence on soil density during the dynamic movement.
