SYSTEM AND METHOD FOR IRRIGATION SYSTEM MANAGEMENT
An irrigation management system includes a water pump, at least one mobile irrigation system, and a pump controller. The mobile irrigation system includes a water pressure sensor for generating water pressure data indicating water pressure in the irrigation system. The pump controller is configured to receive the water pressure data generated by the water pressure sensor, to compare a target water pressure with the sensed water pressure data to determine a difference between the target water pressure and the sensed water pressure, and to adjust operation of the water pump to increase or decrease water pressure to the irrigation system in a manner that resolves the difference between the target water pressure and the sensed water pressure.
