Abstract
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.
