A spring-cushioned coulter running ahead of the applicator for cutting an initial slot in any residue and for providing a break line for the soil to be parted by the trailing shank. The trailing shank, in turn, spreads the initial slot, and deepens it, for the entry of a slurry delivery tube welded behind the shank. At the bottom of the shank is a shoe having a pair of side wings. A downward and outward slope of the wings creates a flat, peaked soil profile ("sole") beneath the wings having sides which slope downwardly and outwardly, conforming to the shape of the wings. The lift surfaces of the wings slightly raise the soil laterally of the shank from the center toward the ends of the wings to provide slots or fissures above the sloped edges of the sole, permitting, and promoting the lateral distribution of the slurry.

[ We claim:] [1.] In an agricultural slurry applicator having a frame, the combination comprising:a coulter mounted to said frame to part the soil and form a slot;a shank assembly adapted to be mounted to said frame behind said coulter and comprising:a shank for forming a slot in the soil behind said coulter;a shin wedge mounted in front of said shank and having a vertical leading edge following in the slot formed by said coulter to widen said slot to a width approximately equal to the width of said shank;a point mounted to the bottom of said shank and extending forwardly thereof;first and second wings mounted behind said point and respectively on either side of said shank each wing having a cutting edge extending outwardly and rearwardly relative to said point, said point and wings cooperating to break the soil in front of said shank and to lift the soil along paths defined by said wings to form fissures without substantial tillage of the soil; anda slurry delivery tube mounted to said shank and extending downwardly in the slot formed by said shank, said delivery tube defining a discharge opening to place slurry immediately behind said shank and adjacent the inboard ends of said fissures formed by said wings, whereby said slurry moves outwardly in said fissures as they are formed by said wings and the soil raised by said wings is free to fall after said wings have passed and said slurry has been placed.
