There are two ways to measure soil moisture: 1 Soil Moisture Tension and. 2 Soil Moisture Content. Soil moisture tension. Soil moisture tension tells you how easy it is to extract water from soil. When a soil is saturated, there is plenty of water in the pore spaces and plenty of water coating the soil particles.All this moisture makes it very easy for plant roots to get water and the soil moisture tension is low.oil moisture tension tells you how easy it is to extract water from soil.
