Soil conductivity sensors

The soil conductivity sensor uses a stainless steel probe to convert the analog or digital signal of the soil conductivity through the sensor. In the development process, it has absorbed the advanced technology of similar foreign instruments. And combined with the actual situation and use requirements of our country. Convert the conductivity value into the corresponding analog or digital signal. After burying this conductivity sensor in the soil. Directly measure the conductivity of soluble salt ions in the soil solution. Stainless steel electrodes have the characteristics of stable performance and high sensitivity. Applicable to a wide range of measurement. Especially suitable for high conductivity, so it is very suitable for the determination of soil conductivity.

The role of soil conductivity:

Soil electrical conductivity plays a guiding role in how plants can fertilize plants. The nutrients required by plants are usually added through compounds. For example, by adding ammonium nitrate to supplement nitrogen. Microorganisms will decompose these compounds to facilitate the absorption and utilization of plants. Soil electrical conductivity reflects the actual status of soil salinity under certain moisture conditions. Affecting the conversion, existence and availability of soil nutrients is the threshold that limits the activity of plants and microorganisms.

Within a certain concentration range, the salt content of the soil solution is positively correlated with the conductivity. The more dissolved salts, the greater the conductivity of the solution. Therefore, it is possible to indirectly reflect the salt content of the soil by measuring the electrical conductivity of the soil. So as to provide guidance for fertilization management. The total soil salinity is increasing year by year, resulting in 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. 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.


Effective acquisition of soil conductivity values is of great significance for determining the differences in the temporal and spatial distribution of various field parameters. It also lays the foundation for the popularization and popularization of modern precision agriculture based on information and knowledge. Therefore, we must learn to use scientific and effective methods. Use modern soil conductivity measuring instruments to obtain data. Then conduct a scientific and reasonable analysis of the data to make our planting more scientific and effective.
