A device (100) for treating soil, in an exemplary embodiment, includes a soil contact head (102), with the soil contact head having at least one discharge orifice therein, a handle (104) attached to the soil contact head, a discharge valve (106) in fluid communication with said at least one discharge orifice, a soil contact indicator (108), and a source of pressurized soil treatment fluid flowably connected to the discharge valve. The discharge valve discharges pressurized soil treatment material through the discharge orifices when the soil contact indicator indicates contact between the soil contact head and the soil. |
