What is soil tension?
During the growth of crops, soil moisture has an important impact on their water absorption and nutrient utilization. Real-time monitoring of soil moisture and understanding of soil moisture changes can not only provide a basis for timely and reasonable irrigation, but also improve crop yields and reduce the occurrence of pests and diseases. Soil tension is soil water potential, which is an indicator of soil moisture intensity. Its size is closely related to the mobility and penetration depth of soil water, as well as the effectiveness and difficulty of plants absorbing soil water. At the same time, it can indirectly reflect soil moisture. Generally speaking, the lower the soil moisture, the greater the soil tension and the stronger the suction of water, making it difficult for plants to absorb water in the soil; the greater the soil moisture, the weaker the soil's suction of water, and the easier it is for crops to absorb water. Water is absorbed into the soil.
Application of soil tension sensor
In modern agriculture, the role of soil tension sensors is very significant. The soil tension sensor can collect the dynamic content of soil moisture of crops. After collecting the data, farmers can implement more precise irrigation measures based on the growth changes of the crops. It can not only record soil tension change data, but also help planting Researchers constantly supplement the soil environment data of crop types, which is of great significance for improving crop varieties, improving crop quality and yield.
