Abstract:: The contents and dynamic evolution of soil water and salt are closely related to agricultural production and the ecological environment. The dynamic monitoring of soil water and salt is a big challenge in the practice due to multiple impact factors such as the crop, soil and cultivation technique. Based on the results of the present study of soil water and salt content effects on the dielectric properties of the soil by using the model, frequency domain reflection technology, using frequency division technology, the high frequency of soil moisture measurement, frequency of soil water and salt content of the comprehensive measurement, and the soil texture calibration method based on elimination effect of water on salinity data, the simultaneous measurement of soil pore salt and water content can be realized. The analysis of the sensor in the application of the 18 monitoring points in Tianjin City has demonstrated the effectiveness and accuracy of the sensor since 2013.
