The broadfork, also called a U-fork or grelinette, is a garden tool used to manually break up densely packed soil, including hardpan, to improve aeration and drainage. Broadforks are used as part of a no-till or reduced-till seedbed preparation process because they preserve the soil structure and avoid the resurfacing of weed seeds.
