Sidewall tensiometer and method of determining soil moisture potential in below-grade earthen soil
Abstract
A sidewall tensiometer to in situ determine below-grade soil moisture potential of earthen soil includes, a) a body adapted for insertion into an opening in earthen soil below grade, the body having lateral sidewalls; b) a laterally oriented porous material provided relative to the body lateral sidewalls, the laterally oriented porous material at least in part defining a fluid chamber within the body; c) a pressure a sensor in fluid communication with the fluid chamber; and d) sidewall engaging means for engaging a portion of a sidewall of an earth opening to laterally urge the porous material into hydraulic communication with earthen soil of another portion of the opening sidewall. Methods of taking tensiometric measurements are also disclosed.
