Alternate Wetting and Drying (AWD) is a water-saving technology that farmers can apply to reduce their irrigation water consumption in rice fields without decreasing its yield. In AWD, irrigation water is applied a few days after the disappearance of the ponded water. Hence, the field gets alternately flooded and non-flooded. The number of days of non-flooded soil between irrigations can vary from 1 to more than 10 days depending on the number of factors such as soil type, weather, and crop growth stage.
Automation can be done with the use of sensors. It is a good idea to have a relevant study about this so we can come up with a device to automatically advice the farmers when to flood and dry the fields. As compared to manual checking, automation can be a good avenue to facilitate better water management
