Title:
MEASURING METHOD OF MOISTURE CONTENT IN SOIL
Document Type and Number:
Japanese Patent JP2016080618
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To easily measure the moisture content in soil.SOLUTION: A calibration curve of a relationship between the specific gravity of a sucrose aqueous solution and the moisture content in soil is previously created. The weight of collected soil is measured. Then, the measured soil is input to a predetermined amount of sucrose aqueous solution that has been prepared so as to have a predetermined concentration, and is stirred. Then, the specific gravity of the sucrose aqueous solution obtained through filtration is measured, and the measured specific gravity is compared with the calibration curve, thereby determining the moisture content in the soil.SELECTED DRAWING: Figure 2
