What crops are most profitable to plant in sandy soil
The editor introduces you to 4 types of crops suitable for planting in sandy soil and shares experience on what is most profitable to plant in sandy soil. Let's learn about it together.
Soils with different structures have different effects on crop growth and yield formation. Sandy soil is loose in structure, has good ventilation and water permeability, and has a large diurnal temperature difference, making it suitable for cultivating crops in sandy soil.
Mainly including crops with the purpose of harvesting underground organs for cultivation, and crops native to desert areas, including the following four types:
1. Root Vegetables
Root vegetables include radishes, carrots, burdock, root celery, horseradish, etc.
This type of vegetable's edible commercial organ is the enlarged fleshy root. In the process of forming the product organ, the relatively loose sandy soil is beneficial for the expansion of the root, and it looks more uniform and aesthetically pleasing, making it easier to harvest and commanding a higher market price.
In heavier,粘稠 soil, due to the strong soil cohesion, the suitable soil moisture range for these root vegetables to expand is small. When the humidity is too high, poor ventilation is不利于 root growth and can even cause root rot.
When the soil moisture content is low, it becomes too compact, and the pressure on the root volume increases, which is not only unfavorable for yield formation but also easily leads to malformed roots with low commercial value.
2. Tuberous Crops
Including yams, sweet potatoes, taros, ginger, Chinese artichokes, Jerusalem artichokes, potatoes, and bean tubers, etc., these crops also aim to harvest underground commercial organs, and sandy soil is conducive to yield formation and quality improvement.
This type of soil is generally not tolerant to waterlogging. In sandy soil, it can渗下 after heavy rainfall within a short time.
However, in clay soil, it often causes prolonged waterlogging, which is unfavorable for root oxygen supply, thereby affecting the normal functioning of root physiological functions and inducing infectious diseases.
3. Peanuts
Peanuts prefer dry and sandy soil. The formation of peanut fruits occurs after flowering above ground, and the pistil penetrates underground to expand and develop. Sandy soil is beneficial for the pistil to penetrate and expand underground.
In heavy soil, due to the high soil pressure and relatively poor soil ventilation, the fruiting rate of the pistil decreases, thereby affecting yield.
The root growth of peanuts requires high soil permeability. In heavy soil, it is prone to root rot due to waterlogging, causing diseases and causing significant losses in growth and yield formation.
Heavy soil can also cause peanuts to be compressed, affecting yield formation and increasing the proportion of malformed fruits, thereby reducing commercial value.
In sandy soil, it is more conducive to peanut harvest, reducing the fruit drop rate in the soil and minimizing losses.

4. Watermelons
Watermelons prefer sandy soil, and watermelons grown in sandy soil have higher quality.
This characteristic is related to their place of origin. The original population of watermelons grows in the desert areas of Africa and has developed a strong adaptability to sandy soil over long-term evolution.
In terms of their growth and development characteristics, the roots of watermelons have a strong metabolic ability during growth.
For these physiological activities to function normally, a large amount of oxygen supply is required as a basis, which is difficult to meet in dense clay soil.
Watermelons are susceptible to many infectious diseases during growth, and the occurrence of these diseases is often related to high soil moisture. Sandy soil has relatively low moisture, making it easier to maintain a dry and loose soil state, effectively reducing the incidence of watermelon diseases.
In addition, watermelons grown in sandy soil have a more pronounced sweetness and flavor, mainly because the diurnal temperature difference in sandy soil is greater.
During the day, the organic matter produced by photosynthesis in watermelons is less wasted due to lower night temperatures and less respiratory consumption in the plant, allowing more nutrients to accumulate in the fruit and increase sugar content.
Moreover, the low water-holding capacity of sandy soil easily causes a deficiency in root water supply, creating a stressful growth environment for watermelons. This process is conducive to the production of secondary metabolites during growth, which are important substances for enhancing the flavor of watermelons.
