Introduction to the function of soil conductivity sensor

Background

When describing the soil salinity, the commonly used index is the conductivity of the soil leachate. In soil analysis, the salt content is an important comprehensive index, and measuring the electrical conductivity in the soil can directly reflect the mixed salt content. The soil conductivity sensor can monitor the salt in the soil very well.

Soil is one of the natural resources that mankind depends on for survival, and it is the foundation of plant growth and development. The state of soil environment is closely related to the survival and reproduction of human society. The total salt content in the soil is the total salt content in the soil. Because various salts in the soil leaching solution generally exist in the form of ions. Therefore, the total salt content can also be expressed as the sum of various cations and various anions in the soil leachate.

Soil conductivity sensor

In recent years, the total salt content of the soil has been increasing year by year. Produce soil acidification and secondary salinization. This is mainly because, on the one hand, the perennial or seasonal soil cover changes the water and heat balance in the natural state (high temperature, lack of rainwater washing, strong evaporation). The soil is not fully leached by rain, causing salt to accumulate on the surface of the soil. On the other hand, it is also caused by unreasonable fertilization. Therefore, it is very necessary to monitor the conductivity of the soil to be able to grasp its pollution status.

The soil conductivity sensor adopts the international new generation FDR measurement method, with an accuracy of less than 3%; using electromagnetic non-contact measurement method, the soil EC sensor will not drift over time, which greatly improves the stability of the product and extends The service life.
