This invention is a device for injecting chemicals into the soil, comprising two embodiments. In both embodiments a disc cuts the soil, making way for a brace with a knife that cuts away the soil further. A nozzle connected to a tube, which draws chemical from a reservoir, sprays the chemical directly into the soil. A belt, which encircles two drums, keeps the vegetation on the soil. In one embodiment the discs are on the drums. In the second embodiment the disc is separate from the drums.
