摘要: A control system (100) is disclosed for an agricultural implement (40), such as an agricultural sprayer, used to dispense a product the ground wherein the dispensing units (10) are provided with valves (14) that can reduce flow rate of product through selected zero. By controlling of dispensing units (10), overlap application to the be substantially eliminated. In alternative embodiments invention, control system receive data from remote source, such as central controller (57) or another (40) operating in field, define where needs to applied ground. The the product also controlled conjunction with prescription map. Preferably, each dispensing unit provided with valve (11) operable associated so each dispensing unit independently to provide variable the ground.
