Why not change "tensiometery" to "potential"?  You can then include 
gypsum blocks, fibreglass blocks and psychrometers (if any are really 
using them for irrigation scheduling).  Also, rather than the term 
"capacitance" perhaps "dielectric" better describes the various 
techniques that purport to rely on this aspect of physics for 
moisture content determination.
