Soil water sensors reveal subsoil conditions – Part 4: Frequency delay measurements by means of capacitance and heat pulse measurements
by Frikkie Koegelenberg, Pr Eng and Hendrik Jordaan Frequency delay measurement is based on the measurement of the dielectrical constant of soil or materials. The frequency delay measurement is also called the radio frequency (RF) capacitance technique. We thank the ARC Agricultural Engineering in South Africa for making their[...]
