Application

Tips: Why is measuring electrical conductivity (EC) in soil important?

Measuring soil EC is crucial for understanding soil fertility and salinity levels, as EC is directly related to the concentration of dissolved salts and nutrients in the soil. High EC values indicate a high concentration of salts, which can affect plant growth negatively by impacting water uptake and root health. By monitoring EC, farmers and horticulturists can make informed decisions on irrigation and fertilizer use to optimize plant health. The Speedy Soil Moisture Sensor’s ability to measure EC alongside moisture and temperature makes it a comprehensive tool for maintaining balanced soil conditions and ensuring optimal growing conditions.

Some Questions

We are evaluating an ATO-SOIL-RSSC2 device designed to support soybean and corn planting decisions (planting depth 3–5 cm). We need to differentiate the moisture content of this soil layer from the average moisture content of deeper soil layers. Please confirm the following before purchasing: Accuracy: Does the displayed moisture percentage refer to volumetric moisture content (m³/m³)? Does the ±2% error refer to absolute percentage points or relative error? Horizontal Installation at 3–5 cm Depth: Can a 60 mm long probe be inserted completely horizontally into an exposed but undisturbed soil profile at a depth of 3–5 cm while maintaining nominal accuracy?

ATO Responded

1. The definition of humidity percentage: Yes, the humidity percentage displayed by this device refers to volumetric water content (usually expressed as %). In the technical specifications, the moisture parameter range is 0-100%, which corresponds to the percentage expression of volumetric water content.
2. The ±2% error refers to absolute percentage points, not relative error; test report data cannot be provided.
3. Horizontal installation at a depth of 3–5 cm has not been tested; this depth may be too shallow. 5–10 cm is recommended.
