A tensiometer is a device used to determine soil moisture tension, an indirect measure of soil moisture content. The tensiometer consists of a glass or plastic tube with a porous ceramic tip. It is filled with a liquid, usually colored water. At the top of the tube is a vacuum gauge. The device 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, the vacuum inside the tube increases and can be measured by the gauge. ...
