An Analysis of the Effects on Calibration Parameters of FDR for Moisture Sensor Caused by Different Kinds of Soils

Abstract:

With the method of artificial soil columns, several kinds of soil, such as, loam, clay, and sandy soil were used for FDR (frequency domain reflectometry) moisture sensor calibration experiment. Then, these data showed that the frequency of soil moisture sensor is monotone decreasing with the increase of soil volumetric water content, so the correlation is obvious. Different kinds of soil affected moisture sensor parameter remarkably. A better result would be obtained in classification calibration than that in concentration calibration. This experimental result had a great meaning for fine calibration of soil water automatic detector in the areas with complex kinds of soil.
