ABSTRACT:
This invention is an apparatus for planting seed and injecting dry fertilizer (dry granular material) with a V-Blade Plow while at the same time tilling the soil. The apparatus consists of a series of circular conveyance tubes that direct the granular material into a groove formed by the apparatus by means of a knife mounted to the underside of a metal plate which also serves as the mounting structure. The seed and fertilizer are injected into the groove, below the compacted sweep layer (formed by the blade) and next to firm soil that does not dry out like the loose soil above the sweep layer.
