Abstract
A variable flow spray nozzle system for delivering a plurality of crop inputs over an agricultural field using a spray boom having a plurality of release zones. Each release zone on the boom is has multiple nozzle modules, and each nozzle module is individually controlled and capable of variable flow. A control system in communication with each nozzle module and a positioning system, such as a GPS system, controls the application of multiple crop inputs so that the crop inputs are applied at a variable prescriptive rate. Thus, it is possible to vary the flow of crop inputs along the length of the boom as well as in a direction substantially transverse to the direction of the boom.
