FIELD: agriculture.

SUBSTANCE: lysimetrical device comprises a perforated housing 1 and a perforated vacuum tube 2 for collecting moisture. The housing is made in the form of a closed hollow cylinder, on the entire side surface of which perforation is made, and which is covered with a water-permeable material of geotextile 3. The ends of the material of geotextile 3 are fixed to each other by a seam, forming a closed cylinder cavity. The perforated openings 5 of the cylinder 1 are drilled along the entire side surface by conical openings tapering into the inside of the hollow cylinder 1. The vacuum tube 2 outside within the perforation inside the housing 1 is covered with the second layer of the water-permeable material of geotextile 6.
