When soil conducts electricity poorly, the goal is to get more current into the earth and reduce resistance at the grounding point. Pouring water around the stake increases soil moisture, which lowers resistivity and improves the grounding path. Moving the stake to a more moisture-rich area places the connection in soil that naturally conducts better, again reducing grounding resistance. Running an extension cable to a metal object provides a larger or more conductive path to earth, which can help when battlefield conductors need a stronger grounding reference. Digging a new trench for more metal object isn’t listed as a standard quick remedy for poor soil grounding because it’s invasive and its effectiveness isn’t guaranteed in the moment or in field compliance contexts; you’re typically expected to use moisture management, repositioning to better soil, or a proper conductive path to an adequate grounding electrode instead.
