At least one electrically controlled injector (212) is provided in fluid communication with a second end of the tubing (86,88). Also, at least one shank (200) is provided, which includes a base (201) and an injector mounting member (203) attached to a surface of the base (201) that is adapted for detachably mounting the electrically controlled injector onto the base (201). In addition, a controller (213) is provided for activating the electrically controlled injector (212) to introduce the material into the soil. Accordingly, enhanced control of the injection of the material into soil is achieved, and maintenance can be performed easily.</p> |
