Claim 15:
16. An agricultural product fluid metering assembly comprising:
a carrier fluid supply configured to contain a carrier fluid;
at least one main line in fluid communication with the carrier fluid supply;
a plurality of product dispensers in fluid communication with the carrier fluid supply with the at least one main line;
first and second agricultural product supplies configured to contain first and second agricultural products, respectively;
a first fluid delivery line in fluid communication with the first agricultural product supply;
a second fluid delivery line in fluid communication with the second agricultural product supply;
wherein the first and second agricultural product supplies and the first and second fluid delivery lines are isolated from the carrier fluid supply and the at least one main line; and
a plurality of metering interfaces configured to inject the first or second agricultural products to the carrier fluid, the plurality of metering interfaces including at least first and second metering interfaces, wherein each of the metering interfaces includes:
a fluid connection in fluid communication with at least one of the first or second fluid delivery lines, the fluid connection proximate to at least one product dispenser of the plurality of product dispensers, the fluid connection downstream from the carrier fluid. supply;
a metering device proximate to the associated fluid connection, the metering device configured to independently control injection of at least one of the first or second agricultural products to the carrier fluid at the fluid connection; and
wherein the first metering interfa.ce is configured to inject the first agricultural product to the carrier fluid proximate to the at least one product dispenser, and the second metering interface is configured to inject the second agricultural product to the carrier fluid having the first agricultural product proximate to the at least one product dispenser.
