A furrow closer for mounting to an anhydrous ammonia fertilizer applicator knife. The furrow closer has a base plate which can be selectively mounted to a mounting bracket fixed to the shank of the applicator knife. A pair of offset fluted disks lie in intersecting planes with the leading edges of the disks spiced further apart than the trailing edges. The disks are suspended of an axle which is pivotable on an axis perpendicular to the line of travel of the applicator knife.
