The use of continuous soil moisture monitoring produced precise information

The depth of the active rootzone
Infiltration and saturation time
The water being sourced from ground water by the crop
The effect of irrigation
Daily crop water use
The evapotraspiration rate

This information was used to set the budget lines including the full point, field capacity and stress point to manage the irrigation:

Avoiding the need to put water under the root zone
Avoiding saturation resulting in plant stress
Reducing 40 % of irrigation, a result of recognizing the real need of the plant
Improving yield quality
