    • An applicator unit for applying slurry fertilizer beneath the soil with reduced soil displacement includes a spring-cushioned main mounting shank and a forward spring-biased colter. A narrow applicator shank is mounted to the main mounting shank by a pair of vertically spaced bolts, including a lower shear bolt, at a location just above the surface of the soil. The sweep shank is generally upright and includes a nose portion at a lower leading edge which includes a generally blunt lower portion and a tapered leading edge for forming a furrow without tilling the soil. The furrow is formed in three stages by the blunt nose pad, the upright tapered leading edge of the sweep shank, and by a pair of mounting plates carrying the slurry tube and widening the top of the furrow.
    • 用于在泥土下施用淤泥肥料的施肥器单元具有减少的土壤位移,包括弹簧缓冲的主安装柄和向前弹簧偏置的收缩机。 狭窄的施加器柄通过一对垂直间隔的螺栓安装到主安装柄上,该螺栓包括下剪切螺栓,位于刚刚在土壤表面上方的位置。 扫掠杆通常是直立的,并且包括在下前缘处的鼻部,其包括大致钝的下部和用于在不耕土的情况下形成沟的锥形前缘。 沟通过钝头鼻垫,扫掠杆的直立锥形前缘以及一对承载着浆液管的安装板并且加宽了沟槽的顶部而形成三个阶段。
