Carrots and Parsnips - 2010 Ohio Vegetable Production Guide
Best production is obtained from deep, porous soils. Raised beds tend to increase the depth of tilled soil and can help provide good root shape. Do not destroy soil structure by overworking soils or working them while they are wet. Some growers roto-till to obtain a deep, friable soil. Hilling soil over the shoulders of the roots at the last cultivation can help reduce greening.
