A resilient seed firming attachment for a planting machine designed to effectively place seed at a consistent depth and at consistent spacing. The attachment may be of any geometrical configuration having a length adequate to firm the seed in the opened furrow and is mounted in a position trailing the discharge end of a seed boot. The resilience of the seed firming attachment being variable and having a control mechanism to ensure that sufficient force is applied to the seed to firm it into the soil at the desired planting depth. By controlling the amount of flex, the proper seed planting depth and firming will be accomplished in a variety of soil and moisture conditions. The seed firming device is also variable so as the amount of down pressure will not modify the depth desired and obtained by the furrow opening device.
