Methods for measuring soil physical properties
The method uses a measuring probe to calculate soil properties by inserting into water and air with known dielectric constants, applying a frequency signal, and detecting the reflected signal to accurately measure soil's relative permittivity and electrical conductivity.

Abstract
To stably measure various physical property values of soil.SOLUTION: A measuring method of physical property values of soil in the ground, includes: a step of inserting a measurement probe 10 into each of water and air, the reference objects with known dielectric constants, applying a frequency signal, calculating two reference values from respective reflection signals, and storing the reference values in a memory; an entry step of inserting the measurement probe 10 into the ground, an actual measurement step of applying the frequency signal to the probe 10 in the ground and detecting a reflection signal from the probe 10; and a calculation step of calculating a relative dielectric constant and an electrical conductivity of the soil on the basis of the reflection signal detected in the actual measurement step and the two reference values.SELECTED DRAWING: Figure 8
