Abstract: 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.

Abstract: A centralized irrigation system provides non-decision-making controllers in combination with a client server architecture that employs irrigation algorithms for monitoring and control. Live feedback means send information back to a server for use with sophisticated modeling capabilities to monitor exceptions to a planned control scheme, adjust control parameters, and provide a real-time update to system performance. This feedback is instantaneously routed from the server to monitoring and feedback client software connected to the server through a network and enables volume-based cycles and soaks of irrigation. Range-based control strategies determine a total volumetric water-holding capacity for a volume of soil and a range of desirable soil moisture. 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.
