Here is a system and method for combining an additive with a carrier fluid in a spray nozzle. The carrier fluid is fed to one or more nozzles that include an embedded Venturi. The Venturi includes an induction port connected to an additive supply. As the carrier fluid flows through the nozzle, the flow creates a vacuum or suction force that draws in the additive. Of particular advantage, the concentration of the additive combined with the carrier fluid can be maintained constant even if the flow rate of the carrier fluid varies. The system and process are particularly well suited for spraying fields, such as crop fields or orchards, with an agrochemical.
