Planting tool
First Claim
1. A planting tool for a movable implement for planting seeds and placing a band of fertilizer in effective proximity beneath the seeds, said tool comprising:
- an elongated, rigid, upright knife adapted to be carried by the implement frame;
a coulter secured to the knife forwardly of the latter in disposition to cut a vertically extending slot in the soil from the surface thereof, said knife being positioned relative to the coulter to hold the slot edges open immediately behind the coulter;
a fertilizer conduit adapted to be coupled with a source of fertilizer for applying the fertilizer to the soil, said conduit having an outlet opening proximal the lowermost edge of the knife for outflow of the fertilizer in a band into the bottom of the slot;
means carried by the knife for cutting a pair of lateral slices into the soil outwardly from the slot on both sides of the latter intermediate the soil surface and the slot bottom; and
means for depositing seeds into the slice and outwardly in both directions from the slot, whereby said seeds are planted in effective proximity above the fertilizer band for nurture of the plants sprouting from the seeds.

Abstract
A planting tool especially for minimum tillage operations has a leading rolling coulter and an elongated, rigid knife behind the coulter to hold open a slot cut in the soil by the coulter. Blades mounted on the vertical knife cut lateral slices in the soil extending outwardly from each side of the slot and between the soil surface and the slot bottom. A fertilizer conduit deposits a band of fertilizer in the bottom of the slot and seeds gravitate through a seed tube onto a V-shaped deflector which directs them in both directions into the lateral slices in the soil. Press wheels mounted on the knife close and recompact the soil after the seeds are planted outwardly and above the band of fertilizer in the slot. The press wheel also serves as a gauge in conjunction with a flexible tool mount to regulate the depth of operation of the tool components relative to the soil surface.
