FIELD: agriculture.

SUBSTANCE: system of subsoil irrigation comprises a source of water, a storage tank (32) with a float control, a field (1) and sectional distributors (2), humidifiers (3) and a device for automatic water supply (4). The float control comprises a vertical distributor (20), inside which the spool (27) is mounted. The spool (27) is connected to the float chamber (32) fluidly connected by the tube (36) with the perforated tubes-storage units (37). The distributor (20) is provided with inlet and outlet holes overlapped by the flap of the spool (27). The spool (27) position change mechanism is made in the form of a rod rigidly mounted in the upper part, having free moving clamps (34, 35). In the mode of manual change in the spool (27) position the elevator (39) with a clamp (40) is moved to the desired height. The elevator (39) interacts with the rod with the moving clamps (34, 35).

EFFECT: simplified structure of the system, reduction of the material consumption, elimination of soil overmoisturising, water saving.
