How does it work? The main Principle:
Inputs via computer:




Time of opening.
Define Shift irrigation time.
Define time between shifts.
Time of closing.
DATA
Processing
Outputs:





Field Layout.
Flow rate report.
Pressure Report.
Total consumption per field.
Electricity consumption analysis.

Computerized System
for Agriculture?
why do we need it?
 Saving direct inputs – water, energy, fertilizer, labour
 Maximizing yields
Quality improvement
Management improvement
Early alert of problems
Even application of water
Even application of fertilizers and dunder

Benefits
 The ability to remotely operate the system
 Monitor operations on a 24 hour basis
 Track operations and delivery from each unit (flow rate &
pressure) from each filter bank and pumping station
 Flexibility (pulse irrigate)
 The ability to tabulate and generate progress and periodic
reports
