The article talks about using computers to help farmers know when to water crops better. They want to find simpler ways than using fancy tools like soil moisture sensors. By studying farm data, a special computer model can suggest when to water crops to save water and get good harvests. This model was tested in Pakistan and showed how farmers can improve their watering techniques using basic information from their fields. The computer program also helps calculate how much water crops need and how much water the irrigation system should provide. It's a tool that can help farmers manage water more efficiently and increase crop yields.
