1. A method, comprising:
selecting a first frequency for an operating signal;
converting the first frequency of the operating signal into a second frequency to create a stimulating signal at the second frequency, the second frequency being a harmonic of the first frequency;
transmitting the stimulating signal into a zone of interest in soil;
receiving a responsive signal based on the stimulating signal;
converting the responsive signal at the second frequency back into the first frequency to create a frequency-converted responsive signal in the first frequency;
comparing a second count of the frequency-converted responsive signal in the first frequency to a first count of the operating signal in the first frequency, the first count and the second count being a number of waves;
determining attenuation of the stimulating signal, the attenuation corresponding to a difference between the first count of the operating signal at the first frequency and the second count of the frequency-converted response signal at the first frequency;
approximating constituent components of the soil in the zone of interest based on the determined attenuation; and
increasing or decreasing a flow of water applied to the zone of interest in the soil based on the approximated constituent components.
