1. A microfluidic manifold for processing an agricultural slurry comprising:
a substrate comprised of a plurality of polymeric planar layers bonded together and having a vertical orientation;
a slurry inlet port formed in the substrate;
a slurry outlet port formed in the substrate; and
a slurry flow path formed internally within the substrate and fluidly coupling the slurry inlet port to the slurry outlet port;
wherein the slurry flow path is configured such that the slurry always flows assisted by gravity in a constant downward sloping direction in all portions of the slurry flow path from the slurry inlet port to the slurry outlet port.
