A device is capable of autonomously burrowing into the earth and, when at depth, discharging a fluid into a geologic formation. The device includes a component body holding a computer controller; a battery; a motor; and a coiled hose. A drill head external to the component body is equipped with a spiral blade that burrows down pulling the component body with it. A cylindrical shell surrounding the component body creates an annulus where debris from the drill head flows upward. The coiled hose is released from the component body as the device descends. An electrical cable may be co-wound with the coiled hose or may be embedded in the wall of the coiled hose. Fluid may be conveyed through the coiled hose to a discharge valve in the component body. The discharge valve is connected to a telescoping discharge nozzle.
