1. A subsurface irrigation system comprising:

  • a plurality of subsurface irrigation sleeves comprising a single-matrix area having a first side and a second side, at least one of the first side and the second side being configured to be hydrophilic, and comprising a tunnel at a fold in the first side and the second side where the first side and the second side are separated from one another to form the tunnel;

    tubing connecting a first sleeve of the plurality of subsurface irrigation sleeves to a second sleeve of the plurality of subsurface irrigation sleeves, the tubing being configured to pass through the tunnels of the plurality of irrigation sleeves; and

    an emitter being disposed on the tubing within the tunnel of each of the plurality of subsurface irrigation sleeves, the emitter emitting fluid to the single-matrix area of the plurality of subsurface irrigation sleeves,wherein the at least one of the first side and the second side is comprised of extruded fibers having a plurality of projections extending from a longitudinal axis, the projections defining longitudinal channels along the fibers.
