A staple for holding sod in place or for fastening erosion control mattings to the ground includes an asymmetric generally J-shaped head portion and two shank portions of different length which extend perpendicularly to the plane defined by the head portion; when the staple is introduced into the ground the head portion exerts a surface pressure on the sod and the shank portions provide a double anchorage of the staple therein. |
