Subterranean Irrigation System (STIS)
A Water-Saving, Growth-Enhancement Device for Irrigating Trees
The STIS technique irrigates trees in a similar fashion as drip irrigation; however, it introduces the water below the soil surface in a closed cylindrical chamber with a permeable fabric in the bottom, resembling a micro drywell. It decreases evaporation losses and promotes deep-root growth. It uses standard emitters residing inside the STIS canister.
STIS Patent Pending.

Holds dissovlable fertilzer
The canister can provide a holding space for dissolvable, solid fertilizer. Every time that the water comes on, the emitter would discharge water on top of the fertilizer material, enriching the water with nutrients as it flows to the roots. This approach might provide an aggressive treatment technique for stressed trees.

Irrigation Conduit where Automated Irrigation has not been Installed
This system can be used to water trees in areas where a water distribution system has not been set up yet. This is done by connecting a passive, constant-flow system (under development by Control Systems Innovation, Inc.). Since the evaporation rate is minimal, is it acceptable to water the trees with a steady and small flow (i.e. drip).

Frostbite Mitigation
Can the STIS reduce the chances of frost by maintaining an upper insulating thermal layer to colder temperatures (because soil on the surface is dry), while simultaneously creating a thermal conducting path to warmer soil temperatures (because lower soil is wet). This is just speculation that is being analyzed.

Minimization of Salt Formation
Can the STIS decreases salt formation around the roots since soil is maintained in a wetter state a larger percentage of the time, keeping salts from drying up as much.
