Abstract
A subsurface irrigation system dries subsurface soil with a tube that is structured to emit water to subsurface soil. The tube has a plurality of emitters that are spaced apart at fixed intervals along the tube and disposed through a wall of the tube. The tube receives water from subsurface soil through the plurality of emitters. The water discharges through a flush pipe of the subsurface irrigation system. The subsurface soil dries passively as water discharges through the flush pipe when a flush valve connected to the flush pipe is open. A vacuum installed on the flush valve may hasten removal of water from subsurface soil. Subsurface soil dries actively as air is introduced into the subsurface soil through the plurality of emitters when the flush valve is open. The subsurface soil is irrigated when water emits through the plurality of emitters when the flush valve is closed.
