WebSoil moisture sensors and water potential sensors work together to show you exactly when it's time to start and stop watering.. DR. GAYLON S. CAMPBELL. Plant available water is the difference in water content between field capacity and permanent wilting point in soil or growing media.Most crops will experience a yield loss if soil is allowed to dry to the … Pore water pressure (sometimes abbreviated to pwp) refers to the pressure of groundwater held within a soil or rock, in gaps between particles (pores). Pore water pressures below the phreatic level of the groundwater are measured with piezometers. The vertical pore water pressure distribution in aquifers can generally be assumed to be close to hydrostatic. In the unsaturated ("vadose") zone, the pore pressure is determined by capillarity and is also refe…
