Precision farming for rice irrigation can be improved by using GIS technology to manage water more efficiently. By accurately estimating irrigation needs and monitoring water distribution, farmers can apply the right amount of water at the right time to improve crop yield. The GIS-based water management model helps in scheduling daily irrigation deliveries and monitoring water distribution to ensure uniformity and prevent water wastage. This approach allows farmers to make informed decisions on where and how much water to apply, ultimately leading to better water management and increased productivity in rice farming.
