There is work being done that will do just that. It is probably
possible to
do it right now. The difficult part is the soil moisture sensor.

In the UK, this isn't really a problem. All soils reach field capacity
at some time during the winter (or in jim's case are permanently
there).

if we have dry soil a foot down then it has been a drought. I remember
once dry soil three feet down, which is unheard of and was after the big
drought in the 70s.

After that it's merely a matter of monitoring transpiration and
knowing
how much deficit you can get away with.
