A flexible seed boot extension fabricated from an ultra-high molecular polyethylene sheet and releasably held in position by a slot and retaining lug so that seed bounce and soil coverage variations are reduced while desired seed flow from the boot to the furrow is unrestricted. The length of the extension is sufficient to prevent seed from bouncing out of the furrow and yet short enough that normal press wheel operation remains unimpeded. The extension, which is constantly in contact with the soil, and is flexible and smooth to easily ride over objects and resist breakage soil build-up.
