Zone control for agricultural product application

摘要

A method of applying a selected first combination of application rates of each of a plurality of crop inputs on a first zone in a field and applying a selected second combination of application rates of each of the crop inputs on a second zone in the field. The method comprises towing a seeding implement through the first zone in the field with metering devices adjusted to apply the first combination of application rates; visually judging when the seeding implement crosses a first boundary from the first zone to the second zone; and, by performing a single action, adjusting the metering devices to apply the second combination of application rates on the second zone.
