Abstract: A method for controlling a delivery of an agricultural product includes measuring an agricultural product flow rate. The method includes inputting a system target flow rate for an agricultural product delivery system and controlling an agricultural product pressure to approach the system target flow rate. An agricultural product system target pressure corresponding to the system target flow rate based on at least one system pressure characteristic is provided. The agricultural product system target pressure is compared with a measured agricultural product system pressure in a pressure comparison to provide a pressure difference and a system pressure is adjusted according to the pressure difference to approach the agricultural product system target pressure.
