is time-of-measurement dependent. That dependency is mainly due to the dynamic nature of some
soil properties (such as soil water content, solution concentration, and temperature).
Although there was nothing technically unsound concerning the research relating EC
a
to
directly or indirectly measured soil properties, an impression was created that EC
a
was a vague,
ethereal measurement that was less than robust due to the spatially heterogeneous and complex
