Abstract
The aim of this work is to present a new supervision and control scheme that has been implemented in an almond and walnut orchard to control irrigation.
Physiological sensors in plants, soil water sensors and a fully equipped weather station were installed in an experimental site.
Furthermore, automatic water supply was enabled using electronic flow meters and electrovalves in the irrigation system.
A central computer was connected to sensors and actuators in order to achieve two main goals: first to collect as complete as possible description of the soil-plant-atmosphere system, and drainage losses, and second to provide irrigation control to save water and to improve the performance of the orchard.
Remote connection to a central computer was implemented to enable remote supervision and control of the system.
At the final steps of the project, the system should work in a fully automatic mode, and operator intervention will not be necessary.
Relevant progresses are expected to be achieved by modelling and controlling irrigation in walnut and almond orchards.
