A MODIFIED MERCURY TENSIOMETER

The present paper introduces a modified type of Hg tensiometer. The manometer in this tensiometer uses the usual principal as for other Hg manometers. However, the main difference is that the Hg manometer is contained within the tensiometer body itself. A relatively small volume of Hg is used and the small mercury reservoir can be filled or emptied rather easily. Once the reservoir is filled, the mercury can usually be safely left for the lifetime of the tensiometer. Tensiometers of the proposed design have been handled successfully for scheduling irrigation on shallow soils by unskilled farmers in Cyprus for the last 4 years. /Author/
