POINT 2 (neutron probe calibrations)
Trevor indicated that many neutron probe calibrations are linear involving
only two factors -- a slope and an intercept.  IF one calibration equation
is satisfactory, then the intercept will not affect ET (the difference in 2
soil water measurements).  HOWEVER, if a profile is not uniform and several
calibration equations are needed to characterize this profile difference,
then the intercepts may be more important factors in determing ET (still
won't affect the layer in question though; but spatial variability of any
layer is "unknown" to the user unless you poke a bunch of holes and ruin
your site!).
