发明名称 Root feeder
摘要 An apparatus is disclosed for depositing a growth altering material such as fertilizer to a plant rooted in soil. The apparatus includes a body member having a handle member extending relative thereto. A digging element extends from the body member having a substantially shovel-like region for digging into the soil upon application of a force on the handle member. A hopper for storing the fertilizer is secured relative to the body member. Gate means is provided in the hopper for containing the fertilizer in the hopper when the gate is in a first position and for liberating the growth altering material in proximity to the digging element when the gate is in a second position. A foot member secured to the body member in a substantially orthogonal relationship may be provided for facilitating digging into the soil. The gate means may be operated by a hand lever secured to the handle member and connected by a flexible cable extending through the body member to the gate means. The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.
