What causes carrot root splitting, and how can it be prevented?

Carrot root splitting can seriously affect yield and quality. Once the roots split, the carrots basically have no commercial value, causing huge economic losses for farmers. So what causes carrot root splitting? How can it be prevented? Let's take a look at the detailed introduction below.

1. Uneven water supply

The main cause of carrot root splitting is uneven soil moisture supply during the growth of the fleshy root. This is especially true when the soil is dry and short of water in the early growth stage, causing the skin to harden. Then in the later stage, with more rain or irrigation, the plant absorbs too much water, internal cells divide faster, and the hardened surface cannot grow correspondingly, thus causing root splitting.

Prevention method: During the carrot growing period, maintain a uniform water supply. Especially in the early stage, take care to keep the soil moist to avoid problems when there is more rain later.

2. Excessive application of nitrogen fertilizer

Nitrogen fertilizer promotes carrot growth. To increase yield, many farmers tend to apply too much nitrogen fertilizer while neglecting other fertilizers, which leads to excessive top growth of the carrot root and speeds up root splitting.

Prevention method: When growing carrots, fertilize reasonably. At the seedling stage, apply mainly nitrogen fertilizer with phosphorus and potassium fertilizer as a supplement. In the middle and later stages, strictly avoid applying nitrogen fertilizer alone and increase the application of phosphorus and potassium fertilizer, which can increase yield and reduce root splitting.

3. Boron deficiency

Carrots have a relatively low demand for boron, but boron is extremely important in the later growth stage of carrots. It can improve carrot quality and make the fleshy root grow more fully. If carrots are severely deficient in boron, their nutrient transport will be hindered, and hindered nutrient transport will lead to carrot root splitting.

Prevention method: During the root enlargement stage of carrots, spray a 0.2-0.3% boron fertilizer solution, which can significantly increase yield and quality and reduce root splitting.

4. Soil causes

Carrots like to grow in loose, fertile soil. If they are planted in soil that is clayey or contains many hard objects, the expansion of the fleshy root will be obstructed, causing forking, root splitting, and similar problems.

Prevention method: Therefore, when planting, use loose and fertile soil. Before planting, prepare the land by clearing stones and other hard objects from the field, and rake the soil fine and level before planting.
