The tensiometer is buried in the soil, and a hand pump is used to pull a partial vacuum. As water is pulled out of the soil by plants and evaporation, the vacuum inside the tube increases. When the soil is wetted flow can also occur in the reverse direction: as water is added to the soil, the vacuum inside the tube pulls moisture from the soil ...
A tensiometer is an instrument used to determine the matric water potential (soil moisture tension) in the vadose zone. [10] An ISO standard, " Soil quality — Determination of pore water pressure — Tensiometer method", ISO 11276:1995, "describes methods for the determination of pore water pressure (point measurements) in unsaturated and ...

Tensiometer may refer to one of a number of devices. The two most common are: Tensiometer (surface tension) an instrument used to measure the surface tension of liquids; Tensiometer (soil science) an instrument to determine matric water potential
The Wilhelmy plate tensiometer requires a plate to make contact with the liquid surface. It is widely considered the simplest and most accurate method for surface tension measurement. Due to a large wetted length of the platinum plate, the surface tension reading is typically very stable compared to alternative methods.
Soil physics is the study of soil's physical properties and processes. It is applied to management and prediction under natural and managed ecosystems . Soil physics deals with the dynamics of physical soil components and their phases as solids , liquids , and gases .
