ABSTRACT:
A surface, subsurface continuous feed moisture maintenance system for microscopic volume irrigation utilizing a preset flow rate valve, provided in a single preset flow rate stage or multiple preset flow rate stages, a moisture actuated sensor valve and a plurality of permeating, moisture distribution tubes. The preset flow rate valves are selected and set according to plant moisture needs in the geographical area being irrigated. The moisture actuated sensor valve gradually opens or closes water flow to the system according to soil moisture level conditions and thus prevents over watering and conserves on water resources. The moisture permeating action of the distribution tubes complement the preset flow rate of the valve and the moisture actuated sensor valve to maintain the subsurface at a constant moisture level.
