Why do carrots crack or split?
If the carrots are coming out of the ground already split it is because of how they have been watered during growing. Carrots are very sensitive to soil moisture levels. Carrots require an evenly-distributed and plentiful soil moisture supply throughout the growing season. When the soil isn’t moist enough, the main root develops many small feeder roots so it can soak up any available moisture more efficiently. At the same time, it forms extra tissue to carry the water, so it becomes tough. On the other hand, if there’s too much soil moisture, carrots sometimes split along their whole length. This happens more often when they are close to maturity. The key to assuring even, sufficient moisture to carrots and other plants is soil that’s rich in organic matter, which enables it to hold moisture, yet drain well. Improve your soil by adding chopped leaves, peat moss or compost, if you can get some. Try to keep the soil evenly moist during periods of irregular rainfall by watering regularly
