1. A system for variable-ratio blending of multiple agricultural products for delivery from an applicator into the ground via a multi-ported opener, wherein the opener has opener conduits extending from corresponding ports in the upper end of the opener to corresponding outlets on the lower end of the opener, the system comprising:

  • a support frame adapted for mounting to the applicator, and wherein said support frame is adapted for mounting of the multi-ported opener thereto for engagement of the lower end opener into the ground,a plurality of metering assemblies mounted to said support frame, wherein each metering assembly of said plurality of metering assemblies includes a local hopper, an independently actuatable motor and a metering device, wherein said local hopper feeds agricultural product to said metering device and said metering device is driven by said motor so as to controllably meter the agricultural product from said local hopper,a selectively actuatable flow re-director cooperating with said plurality of metering assemblies,a manifold having a plurality of chambers, wherein each chamber of said plurality of chambers extends between a corresponding chamber inlet and a corresponding chamber outlet, wherein said plurality of metering assemblies exceeds in number said plurality of chambers in said manifold and wherein flow of the agricultural product from each said metering device is selectively directed by said flow re-director into said chamber inlets of said plurality of chambers in said manifold for blended delivery of the agricultural product from said chamber outlets into the opener conduits when the opener is mounted adjacent to said manifold in cooperation therewith for flow of the agricultural product from said chamber outlets into the parts of the upper end of the opener, anda seeding drill having at least one arm, bulk storage compartments associated with said drill for the bulk storage of separate and different agricultural products, wherein said drill is adapted for selectively conveying the agricultural products from said bulk storage compartments to said at least one arm of said drill, a laterally spaced apart array of said support frames and corresponding said pluralities of metering assemblies, said flow re-directors and said manifolds mounted along said at least one arm and further comprising said multi-ported openers mounted to said support frames, depending downwardly therefrom in said cooperation with said manifolds, wherein said number of metering assemblies in each said plurality of metering assemblies is equal to or less than the number of said bulk storage compartments, and wherein said plurality of chambers in each said manifold equals in number the number of said conduits in said opener.
