ABSTRACT:
A field type granular fertilizer applicator includes a mixing unit for putting the fertilizer into the air carrier medium stream for conveying it to a plurality of applicator knives. The mixing unit includes a passageway between the inlet and the outlet which has a 180.degree. curve with an alternate path that returns to the inlet thereby providing a 360.degree. turn. The granular material is fed into the mixer unit at the approximate radius of curvature center for the curved passageway. The centrifugal movement of the air produces a vacuum at the radius of curvature center allowing for gentle acceleration of the granular material.
