Description
Soil electrical conductivity (EC) is the level of salts in soil (salinity). These parameters are vital indicators of soil fertility and health and ultimately affect the plants. When there is a high soil salinity, the salt will make it difficult for the plants to consume water even though there is a high moisture level in the soil. This situation will ultimately "burn" the plants. Plants grow best in their preferred environment, within the optimal ranges of soil moisture, temperature, and EC level. Growers need to have data on these parameters and understand what actions need to take to ensure plant health and higher yield.
This Soil Moisture & Temperature & EC Sensor MODBUS-RTU RS485 is designed with industry standards, featuring high precision, high sensitivity, and durability. Incorporating three sensors (soil moisture sensor, soil temperature sensor, and soil electrical conductivity) into one, and it comes with auto temperature compensation, this sensor ensures the accuracy of measurements regardless of the environmental changes.
By measuring the dielectric constant of the soil, it can stably measure the soil VWC (volumetric water content) regardless of various soil types. The measurement conforms to current international standards for soil moisture measurement.
The stainless steel probe can be permanently inserted into the soil with quick testing for long-term use. This soil sensor is IP68 rated, very robust and durable, and suitable to be applied for long-term monitoring of soil moisture, temperature, and electrical conductivity at scientific experiments, water-saving irrigation, gardening, greenhouses, outdoor farming, horticulture, golf turf management, forestry, precision agriculture, and other professional environmental monitoring scenarios. This sensor can also be used to measure EC levels in the water, nutrient solution, and other substrates.

FAQ
| Q: | What exactly is soil moisture measured? |
| A: | Measured is soil volumetric water content, soil volumetric water content %= soil volumetric water content * bulk density |
|
|
|
| Q: | How is soil volume water content measured? |
| A: | By measuring the dielectric constant, and then through a certain calculation formula to convert into soil volume water content. |
|
|
|
| Q: | Why does the measured volume water content of soil not reach 100% in water? |
| A: |
First of all, the saturated water content of the soil is about 60%, and the measurement of higher water content is not of practical significance. Second, we need to pay attention to the test environment and method when testing. 7*7*7cm square column range measured by the sensor probe. If water is used for the test, a container of at least 20*20*20cm is required, and the probe is placed in the middle (with water to immerse the probe). The resulting value will be between 80% and 100%. |
|
|
|
| Q: | How to install a soil sensor probe? |
| A: |
Dig a vertical hole, insert the sensor steel needle into the hole to be measured, and then compacted the pit to ensure that the steel needle is in close contact with the soil.
|
|
|
|
| Q: |
Is the conductivity affected by the soil moisture? |
| A: |
The EC value can be continuously monitored in the field, mainly by measuring Bulk EC value, which is related to soil water content. If there is no water or little water content, the ions in the soil cannot dissolve in the water, and conductivity will be low.
