LYSIMETER Russian patent published in 2017 - IPC G01N33/24 G05D9/00 

FIELD: agriculture.

SUBSTANCE: lysimeter includes the container (1) with the soil monolith, communicating with the vertically installed container (6), the pallet (5), the valve (11), the retainer (16) of the valve (11) position, and the water level control elements. The vertically installed container (6) is divided into two unequal parts (8, 9) by the vertical perforated partition (10), and one part of the container (8) is communicated via the pipe with the container (1) with the soil monolith and is made with the valve (11) placed inside, rigidly fixed to the vertical rod (13) with the pointing arrow (14) located above the cover (15) of the container (6). The valve (11) is made in the form of a ball equipped with a visor (12) on top, and is arranged with the possibility to overlap the outlet opening (18) in the horizontal partition (19) fixed in the middle part of the container (6). Wherein the valve (11) in the lower part is additionally provided with the guide rod (20) passing through the outlet opening (18) in the horizontal partition (19). The side wall of the container (6) above the cover (15) is equipped with the graduated column (21) in the form of a scale opposite the pointing arrow (14).

EFFECT: higher reliability and convenience of conducting the research on experimental plots, as well as reducing the complexity of controlling low-pressure water feeding of the plots to be investigated near the natural field.
