On the go in-situ soil gas sampling

A soil gas sampling implement, comprising:

• a soil gas sensor system configured to sample soil gas at multiple depths from soil of a field being traversed by the implement and configured to generate a soil gas content signal corresponding to a concentration of one or more soil gas constituents of the soil gas sampled by the soil gas sensor system, the soil gas sensor system including at least one sensing probe configured to collect soil gas samples;
• a position sensor configured to generate a position signal corresponding to a geographic location of the implement within the field;
• and
• a controller functionally linked with the soil gas sensor system and the position sensor for receiving the soil gas content signal and the position signal, the controller being configured to send a command signal to the soil gas sensor system to adjust a sensing depth at which the soil gas is sampled as the implement traverses the field.
