A hoe is an ancient and versatile agricultural hand tool used to shape the soil, control weeds, clear soil, and harvest root crops. Shaping the soil can be piling soil around the base of plants (hilling), creating narrow furrows (drills) and shallow trenches for planting seeds and bulbs. Weed control with a hoe can be by agitating the surface of the soil or by cutting foliage from the roots, and clearing soil of old roots and crop residues. Hoes for digging and moving soil are used harvesting root crops such as potatoes.
