What Is Soil Tension?

Soil tension is defined as the suction exerted by soil particles on the water they hold. To extract water from the soil, plants must exert suction on that water. As the soil dries, its tension increases, and it becomes harder for plants to extract water from the soil. The amount of energy a plant must spend to extract water from the soil is directly linked to soil tension.

Plants and trees can adjust their own water use based
n soil tension
The root system can command the leafs to stop the

photosynthesis activity to preserve water.

There is no visible evidences of this stress – it has to be

very severe before it becomes visible

In crop production, this mechanism is very costly as it

translates into a succession of yield losses

To maximize yields and profitability, tension must be

managed within a narrow bandwidth

Benefits of Soil Tension for Irrigation Management

Exact Measurement
Directly linked to plant stress and/or plant

needs

Tensiometer (tool used to measure soil

tension) acts like a mechanical root

Proven technology dating back to the 1950’s
