Abstract: A method to precisely meter and dispense two or more crop inputs with a common metering disc is presented to achieve proper placement in the soil relative to one another. In one embodiment, dry granular or granulized fertilizer is metered from one side of the disc and seed is metered from the opposite side of the same metering disc. The fertilizer is placed in a concentrated “pulse” approximately equal distances between seeds within a common seed furrow and/or between seed furrows to improved nutrient use efficiency by minimizing soil to fertilizer contact and subsequent chemical reactions that make applied supplemental nutrients less available to plants. Pressurized air may be utilized to assist discharge of both the seed and fertilizer from the disc meter to assure precise spacing in the soil. A cover may be placed on the meter and metering disc to recirculate air and thus minimize potential atmospheric contamination from seed coatings and fertilizer materials.

Abstract: A distribution system for a drill, having a body defining first and second outlets in communication with a delivery system of the drill. The body includes at least two first and two second containment units. The first containment units are in communication with only a first one of the two outlets, and the second containment units are in communication with only a second one of the two outlets.
