Abstract

A tool bar for placement of a band of fertilizer in soil has a vertical knife with a horizontal blade thereon to create an inverted T-shaped slot in the soil. A band of fertilizer is placed in the bottom of the slot through a tube on the knife. A first coulter fills the slot with soil and compacts the soil above the band. A second coulter forms a mound of soil over the compacted soil and creates an elongated furrow in the soil above and laterally removed from the band. The method of placement of a band of fertilizer in soil sequentially moves the soil and creates the band as accomplished by the foregoing structure.
