A liquid capture tray and conservation system for capturing agricultural liquids which would otherwise be wasted and could contaminate groundwater. The liquid capture tray has a tray body and a reservoir matrix across the tray body. The reservoir matrix has a plurality of adjacent interconnected concave liquid capture cups, each with a sidewall and bottom wall defining an upwardly disposed reservoir. The tray is positioned below the root zone of a plant growing area to capture liquids that pass through the root zone into the reservoirs of the cups. Apertures in the tray body allow excess liquids to drain from the tray. A connecting mechanism can be utilized to connect two trays together. Cut-outs in the sidewalls of the cups allow liquid to move from one cup to another to disperse liquid across the reservoir matrix. The system includes a growing area, root zone, liquid and liquid capture tray.

A smart root watering system is disclosed. The system includes a controller, configured to control the system using artificial neural networks. The system further comprises vertical tubes, inserted into the soil proximity to the roots of trees and configured to deliver water to the roots of trees. The vertical tubes include a motion sensor, configured to detect variation in water flow and wirelessly send data to the controller, thereby indicating faults of the vertical tubes to the user via a handheld electronic device. The vertical tube further includes a mechanical valve with a floater, configured to regulate input water to the system with respect to the soil absorption. The system further comprises a sensor device, configured to detect the humidity level and send to the controller. The controller is further configured to estimate the required volume of water and open an electric valve for supplying water to the roots of trees.
