ABSTRACT:
A dual air system for separately conveying fertilizer and seed in an implement such as an air drill or air seeder which includes an adjustable divider arrangement for providing a small amount of starter fertilizer to be placed with the seed. The total fertilizer metered by a fluted feed wheel is divided into two streams by an adjustable knife plate. A pivoting baffle plate resting against the knife plate deflects one of the two fertilizer portions to the fertilizer air system. The other fertilizer stream is delivered to the seed air system. The overall rate of fertilizer application may be adjusted without affecting the total amount of fertilizer provided to the seed air system.
