Unlike other measurement methods discussed in this special issue, time domain reflectometry (TDR) has the ability to measure both water content ( θ) and apparent electrical conductivity (EC a) of soils. From simultaneous knowledge of θ and ECa, the soil solution electrical conductivity (EC s) and even the concentration of specific ionic constituents such as NO 3–nitrogen may be estimated through soil-specific calibration. This paper provides an introduction, some theoretical background, and a… CONTINUE READING
