System, method and apparatus for spraying the leaf and root areas of plants

A system for use with an irrigation system having at least one span and a drive system for moving the span, wherein the system comprises:

• a first applicant flow system for moving an applicant from a first repository to a first dispersal system;
• wherein the first repository is connected to the first applicant flow system through a first valve;
• wherein the first repository contains a first chemical;
• a second applicant flow system for moving an applicant from a second repository to a second dispersal system;
• wherein the second repository is connected to the second applicant flow system through a second valve;
• wherein the second repository contains a second chemical;
• a third applicant flow system for moving water from a water supply source to a third dispersal system;
• wherein the water supply source is connected to the third applicant flow system through a third valve;
• a plurality of sensors;
• a programmable logic device (PLD), wherein the PLD is configured to analyze sensor data from the plurality of sensors to determine a foliar property of a scanned crop;
• and
• a control system, wherein the control system is configured to control the first valve, the second valve and the third valve;
• wherein the control system is configured to open and close the first valve to modify a flow of the first chemical into the first applicant flow system;
• wherein the control system is configured to open and close the second valve to modify a flow of the second chemical into the second applicant flow system;
• wherein the controller is further configured to open and close the third valve to modify a flow of water into the third applicant flow system;
• wherein the PLD is configured to determine whether a foliar property satisfies a first precondition;
• wherein the PLD is configured to open the first valve to allow the first chemical to be disbursed through the first dispersal system based on the detected first precondition;
• wherein the PLD is configured to determine whether a foliar property satisfies a second precondition;
• wherein the PLD is configured to open the second valve to allow the second chemical to be disbursed through the second dispersal system based on the detected second precondition;
• wherein the PLD is configured to determine whether a foliar property satisfies a third precondition;
• wherein the PLD is configured to open the third valve to allow the water to be disbursed through the third dispersal system based on the detected third precondition.
