  On the other hand, what the crop cares about is water potential, not 
  soil water content, so the low sensitivity of a tensiometer to large 
  water content changes near field capacity poses no threat to the 
  crop. But when the water potential starts to dive, even if the change 
  in water content is small, you better start to irrigate!

I am not sure that I understand this issue of the "low sensitivity of a 
tensiometer to large water content changes near field capacity".  I would say 
that it is opposite, with the tensiometer very sensitive.  Am I missing 
something in prior messages?
