Abstract
A method for monitoring and controlling chemical concentration in a direct injection agricultural sprayer system monitors initial chemical concentration output from a chemical tank, carrier flow from a carrier tank, and mixed chemical concentration at nozzles of the spray system downstream of individual mixing points of the nozzles. Flow from the carrier tank and/or the chemical tank are controlled to target a set concentration at each of the nozzles. The initial chemical concentration establishes maximum concentration and a calibration curve for a chemical being applied and the mixed chemical concentration establishes an applied concentration in view of the calibration curve. A system is provided for the method.
