Tensiometers

Tensiometers are tools used to measure soil moisture levels by assessing how tightly water is held in the soil. They typically consist of a sealed tube filled with water and a porous ceramic tip that contacts the soil. When inserted into the ground, the moisture in the soil affects the water in the device, creating a vacuum that can be read with a gauge. This measurement helps farmers and gardeners determine when to water, ensuring plants get enough moisture without overwatering, promoting healthy growth and water efficiency.
