Description of practice
Irrigation optimization is a water-saving scheme using precise irrigation scheduling. Irrigation system managers determine the correct frequency and duration of watering to minimize costs and maximize yields.
| Examples of how to use irrigation optimization | Further information (see Note below) |
|
|
|
Soil sensor networkSensors are used to measure soil moisture and temperature at different depths in the rooting zone. The farmer can retrieve the data at any time using his mobile phone or computer. |
|
|
|
Portable soil moisture sensorSoil moisture sensors are used by the farmer to manage seasonal water application. This smart irrigation is essential to refine irrigation techniques and to meet specific soil and crop needs. |
|
|
|
Local agreements on irrigation managementLocal agreements between water users are made to prevent and manage conflicts concerning irrigation water. Under conditions of water scarcity, agreements ensure that irrigation water is used rationally and sustainably. |
|
|
|
Alternate wetting and dryingIrrigation is only supplied to a (rice) field whenever the soil moisture content reaches a certain level. This scheduling reduces water input without significantly affecting the yield. |
