FIELD level
Decision making… Quick facts …
• Irrigation scheduling is the process of deciding when and how much water to apply to a field
• The purpose is to maximize crop yield and save water
• Irrigation scheduling procedures consist of monitoring indicators that determine the need for irrigation
WHEN? andHOW MUCH?
4
If you can’t measure –you can’t manage!!
Labour Means Time
In order to do irrigation scheduling we need to know field soil moisture content
5
Objectives
• Obtain actual ET information
• Guide farmers on when and how much irrigation water to apply
• Efficient water use
Development of technology for water management at field level using remote sensing technology
6
Methodology Weather station data
Penman-Monteithequation
REFERENCE crop evapotranspiration computation
Kc – NDVI satellite data
Irrigation scheduling
Si+1=Si+Ii+Ri-DPi-ETi
ACTUAL crop evapotranspiration
ETi=Kc*ETref
7
Methodology
Remote sensing imagescan be used to directlyestimate actualevapotranspiration
Results of imageprocessing allow farmersto treat only affectedareas of a field
Problems within a fieldmay be identified withRemote sensing beforethey can be visuallyidentified
Example of ET of sugar beets (mm/week) for different canals branches within irrigation scheme In Egypt.

Conclusion
Efficient water use
In time
Accurate

Concluding remark!!
This technology will only work if the
irrigation delivery system has the
capability to supply water on demand!!!
