CON2: Management of Soil Moisture and Nitrate Transport Using Sensor Networks and Feedback Control


An issue associated with agricultural irrigation using reclaimed wastewater is the potential threat to underlying groundwater quality. A prime example is nitrate, which serves as a fertilizing agent but has the potential to leach into groundwater. In order to balance water reuse and groundwater protection, intelligent irrigation monitoring and management systems are required to manage water reuse. In this work, a wirelessly networked sensor array is being designed for deployment at an agricultural research plot. The sensor array is coupled to a simulation and management algorithm to optimize irrigation scheduling.
