ABSTRACT:
A seed furrow cutting knife adapted for cutting a seed furrow, fluffing the furrow sidewalls to avoid soil compaction, and for offset placement of fertilizer in the furrow is provided. The furrow cutting knife has associated side wings for fluffing sidewalls of the seed furrow and for simultaneous discharge of liquid fertilizer through a fertilizer tube into the seed furrow, but offset from the bottom of the seed furrow to avoid burning of the seed.
