The layer of charcoal and salt helps to maintain low resistance for earth fault currents. Because of ionic behavior of salt and charcoal they will maintain moisture content around the earthing pit.

If we add salt and charcoal then the soil resistance will become low and the leakage current can easily flow into the earth.
