Water scarcity is likely to increase in the coming years, making improvements in irrigation efficiency increasingly important. An emerging technology that promises to increase irrigation efficiency substantially is a wireless irrigation sensor network that uploads sensor data into irrigation...

We present a dynamic intraseasonal model of optimal investment in irrigation precision that takes into reductions in disease losses and acceleration of crop growth as well as water savngs. We derive the optimal levels of water use, investment in precision equipment and timing of harvest under...
