摘要：
An improved fertilizer knife assembly includes a shank member for attaching to the bracket piece of a fertilizer implement, a point member and a fertilizer tube. The point member is removably mounted to the shank member and includes a chisel like leading edge and opposite generally flat flank portions. The flank portion presents a pattern of crumbler ridges. The leading edge and the crumbler ridges break and crumble the soil into small clumps so that the fertilizer knife assembly leaves a narrow furrow filled with crumbled soil so that the fertilizer tube may deposit fertilizer which is trapped at the bottom of the furrow as the improved fertilizer knife assembly drafts through soil.
