Abstract

An improved particulate metering system is provided with variable blend, application rate, and section control. The system includes a plurality of particulate mixing areas, each having an air input and a plurality of particulate inputs. A plurality of particulate sources is provided, each being in communication with a particulate input of a particulate mixing area. A separate type of particulate can be in each of the plurality of particulate sources. The system includes a plurality of operated conveyances, each being in communication with a particulate source and a particulate input. Each of the plurality of particulate mixing areas can receive air from the air input and a separate type of particulate, and can discharge an air-particulate mixture. One or more metering controls operably control one or more of the operated conveyances.
