<P>PROBLEM TO BE SOLVED: To simply determine the properties of soil. <P>SOLUTION: A soil sensor includes first electrodes 12 to be in direct contact with soil 28, a reference material 16 with water permeability and water retentivity, second electrodes 14 to be in contact with the soil 28 through the reference material 16, and a determination unit 36 that determines properties of the soil 28 on the basis of permittivity of the soil 28 measured using the first electrodes 12 and permittivity of the reference material 16 measured using the second electrodes 14. <P>COPYRIGHT: (C)2013,JPO&INPIT |
