Abstract

An agricultural particulate material delivery system for delivering metered agricultural particulate material to a growing medium includes first and second compartments adapted to contain different agricultural particulate materials, a material meter having an interior and a flow switching mechanism between the first and second compartments and the meter. The flow switching mechanism is actuatable between a first position in which the flow switching mechanism supplies material from the first compartment to the interior of the meter, a second position in which the flow switching mechanism supplies material from the second compartment to the interior of the meter and a third position in which the flow switching mechanism stops the supply of material from both the first and second compartments to the interior of the meter.
