Why is it better to grow sweet potatoes in the sand?

Usually, people choose flat land when planting sweet potatoes, but the land has high compactness and dense soil. When it is too dry, the land is easy to agglomerate, so the yield is not very high. However, sandy soil has loose soil, good ventilation and large temperature difference between day and night, which will not cause soil agglomeration and is most conducive to the formation and expansion of potato blocks.

Although the lack of nutrients in sandy land can not promote the growth of plants, the fertility of sandy land can be enhanced through scientific conditioning.

Because of the loose soil and large gap in sandy land, it is difficult for pests and diseases to survive for a long time. Compared with other lands, there are fewer pests and diseases, and sweet potato seedlings are less affected by pests and diseases in the soil during their growth, and the plants grow vigorously. The sandy land is well ventilated, and the surface temperature will not be too high even under the high-temperature daytime photosynthesis, which can effectively avoid the burn caused by the high surface temperature after the sweet potato seedlings are planted, thus forming weak seedlings or dead seedlings. Therefore, sandy land is more suitable for the growth of sweet potato.
