A standard fertilizer applicator with coulters and shank assemblies with knives for placement of fertilizer below the soil surface is equipped with cultivator shank assemblies to provide complete tillage between the fertilizer shanks. Each cultivator shank is mounted by a plate having notches therein for adjusting the vertical height of the assembly. The plate is attached to a support bracket placed around a square beam or tool bar. When used for spring application, leveling of uneven soil is accomplished and weeds are eliminated with the same pass made to apply the fertilizer.
