Abstract: Systems, devices, and methods are disclosed for increasing the operating range of agricultural liquid application equipment by combining pulse-width modulation (PWM) at individual nozzles with dynamic pressure range control at the boom or section level. A controller determines a pressure operating band based on nozzle attributes or operator input and coordinates pressure and PWM duty cycle to achieve target application rates while maintaining droplet size targets. In some implementations, the boom is sectioned, with section-specific pressure regulators enabling graduated pressure profiles for turn compensation.
