Abstract
A fertilizer dispensing disc assembly is adapted for direct attachment to a planter unit for vertical movement in unison so that fertilizer is dispensed at a uniform depth relative to the planted seeds. The ground opening coulters of the assembly are caster-mounted forwardly of the planter disc, thereby preventing interference with the steering of the planter implement.
