FIELD: agriculture, in particular, subsurface moistening with mineralized water.
SUBSTANCE: subsurface irrigation system has steam-like moisture preparing unit, and supply pipelines hydraulically communicated with network of subsurface perforated moisteners having length sufficient for reaching upper boundary of soil layer with set moisture content. Area of perforation openings of moistener is increasing from the top to the bottom to provide moistening of vertical conical volume of soil around moistener widening toward lower end. Subsurface irrigation system allows plant growing conditions to be improved.
EFFECT: reduced consumption of water, decreased material and power consumption for operation of system, increased effectiveness and reduced agricultural product costs.
