About pF and soil moisture
Soil has a tendency to absorb water. The soil tries to suck up the water in the tension meter.
The drier the soil, the more water it tries to absorb. The drier the soil is, the greater the force to absorb the water.
The drier the soil, the greater the force of suction, and the greater the movement of the vacuum gauge needle. The more the soil is dry, the greater the force of suction and the larger the needle moves.
This suction pressure is expressed as a numerical value called pF.
