Abstract
Metering devices for an agricultural implement are present for applying a field input, for example, pneumatically delivered granular product including seed or fertilizer or sprayed liquid product including fertilizer and the like, to an agricultural field. In the applying of the field input, the rate of application of the dispensers of one section of the implement can be collectively varied in relation to the rate of application of the dispensers of a different section of the implement frame.
