I think one (the upper?) of the tsoil a probes has been uncovered - the data from
one of the 12 tsoil probes is significantly higher (now, during the morning)
than the others. I'll try to check this now.
P.S. Upon looking, it appears that a surface crack, caused by soil drying, has
opened up, exposing the probe directly to air. I haven't done anything about it
since the next irrigation cycle should seal it up again.
