For the curious, here is data from FloraPulse sensors installed with our partner OLIVOS riego in prune, cherry and grape. The sensors were installed in Chile and have been running splendidly for 2-3 months now, and compare favorably with the pressure chamber. Plots below show the midday stem water potential (midday SWP, black lines) data from FloraPulse, as compared with the pressure chamber (stars). The colored columns represent the crop water status (green is well-watered). The 24/7 data shows continuous readings of the stem water potential (SWP) over the same period.
Now to let the data speak for itself!
Midday Stem water potential in Prune
24/7 Stem water potential in Prune
The plot below shows two sensors installed in the same prune tree. The agreement between them is phenomenal, which indicates the readings are very accurate. You can't get agreement this good with the pressure chamber due to user error.
