Patent ID: 7280892

Claim:
A closed-loop system operated by a user for performing sap flow monitoring and measurement, and for simultaneously performing data-logging thereof in a field having a first plurality of plants, and for simultaneously calculating sap flow attributes for said first plurality of plants based upon said logged sap flow data so that irrigation-water may be applied to replenish water consumed by transpiration of said first plurality of plants in said field; said system comprising: a dedicated microprocessor for providing real-time automatic closed-loop irrigation control with a second plurality of sensors and devices disposed in said field; said second plurality of sensors and devices including: a third plurality of sap flow gauges adapted to be attached to and detached from said first plurality of plants, and for automatically monitoring of said sap flow in said first plurality of plants; a water reservoir interconnected with a fourth plurality of pipes interconnected with a fifth plurality of valves, for automatically distributing said calculated quantity of said irrigation-water to said first plurality of plants in said field to irrigate said field; and power means interconnected with said dedicated microprocessor and said fourth plurality of pipes interconnected with said fifth plurality of valves for automatically driving said closed-loop system and said quantity of said irrigation-water.
