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 to the side of the seed adjacent the furrow sidewalls, comprising:
- a furrow cutting knife for cutting a seed furrow to have a bottom and sidewalls, said cutting knife having a pair of knife wings for fluffing said furrow sidewalls and means for discharge of liquid fertilizer offset from the bottom of said seed furrow but in said furrow adjacent or on the sidewalls;
- and
- wherein said pair of knife wings are disposed on each side of said knife, said pair of knife wings being substantially flat along the surface of the wings and having a leading and a trailing edge, said trailing edge being substantially straight and perpendicular to the path of travel of the knife, said trailing edge having a flat upwardly projecting rear portion, and wherein said knife wings each have a wing tip formed at the outer portion of the knife wing and being parallel to the remainder of the knife wing.
A tiller for offset placement of a liquid comprising:
- a furrow cutting knife adapted for cutting a seed furrow having a bottom and sidewalls;
- a pair of knife wings coupled to the cutting knife, said wings being substantially flat and disposed generally parallel to a ground surface, said wings having a trailing edge substantially perpendicular to the path of travel of the furrow cutting knife, said trailing edge including a flat upwardly projecting rear portion;
- and
- a pair of liquid discharge tubes each in communication with a source of liquid, said tubes adapted to discharge said liquid behind said upwardly projecting rear portion and proximate said trailing edge of said wings offset from said furrow sidewalls.
