摘要:
An improved fertilizer knife presents a leading edge, a first flexible fertilizer tube receiving portion and a second fertilizer tube receiving portion. The first and second flexible tube receiving portions are precision cast to frictionally receive the distal end of a flexible polymer fertilizer tube. The first and second flexible tube receiving portions are adapted so that the second flexible tube receiving portion can be mounted to the first flexible tube receiving portion. Both flexible tube receiving portions also each have at least one opening at their lower ends for allowing fertilizer to escape from a flexible fertilizer tube.
