Soil Tension Sensor

Soil Tension Sensor

The development of agriculture depends not only on producers, production tools and production resources, but also on uncontrollable factors such as climate and soil. When environmental factors fluctuate violently, it is easy to cause agricultural disasters, thereby causing economic losses for agricultural workers. loss. Therefore, it is of great help to agricultural production to strengthen agricultural meteorological services, expand the scope of agricultural environmental monitoring as much as possible, and do a good job in disaster prevention in advance.

What is soil tension?

In the process of crop growth, soil moisture has an important impact on its water absorption and nutrient utilization. Real-time monitoring of soil moisture and mastering the changing laws of soil moisture can not only provide a basis for timely and reasonable irrigation, but also improve crop yield and reduce the occurrence of pests and diseases.

Soil tension, or soil water potential, is an indicator of soil water strength. Its size is closely related to the mobility and penetration depth of soil water, and 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 humidity, the greater the soil tension and the stronger the suction to water, making it difficult for plants to absorb water in the soil; Absorb moisture in the soil.

Applications of Soil Tension Sensors:

In modern agriculture, the role of soil tension sensor is very significant. The soil tension sensor can collect the dynamic content of soil moisture in the planted crops. After collecting the data, farmers and friends can carry out more accurate irrigation measures according to the changes in the growth of the crops, which can not only record the soil tension change data, but also help planting. It is of great significance to improve crop varieties, improve crop quality and yield.

The soil tension sensor can visually observe the water level, has a fast response speed, and can effectively sense the soil environment. Not affected by salt ions in the soil, agricultural activities such as chemical fertilizers, pesticides, and irrigation will not affect the measurement results, and the data is accurate. It supports 10-24V wide voltage charging, adopts the standard Modbus-RTU485 communication mode, and the communication can reach 2000 meters.

Soil tension sensor installation location selection

1. Install the equipment after the crops are sown; 

2. The installation location needs to be flat; 

3. Under the condition of comprehensive irrigation, the area with less water is preferentially selected as the monitoring location;

4. Under local irrigation conditions, select the wet area as the monitoring location;

5. Select a position where the growth of crops is balanced and can represent the growth of most crops;
