A centralized irrigation system provides decision-making or non-decision-making controllers in combination with a client server architecture that employs range-based irrigation algorithms for monitoring and control. Range-based control strategies determine a total volumetric water holding capacity for a volume of soil and a range of desirable soil moisture in a root zone, and compare a calculated root zone soil moisture to that range in order to determine the volume of water to be applied during an irrigation event. The system permits a shared-savings business model where the vendor provides a system and the customer only pays the vendor a portion of the savings obtained by using the system.

The efficiency of an irrigation system on a property is determined as a difference between the actual water usage at a property and the irrigation water need of the plant on the property. Data for the property are received including at least the location and irrigation area of the property.
