What has greater matric potential clay or soil?

What is matric potential in soil? Soil matric potential (SMP) is realistic criterion for measuring soil water availability to plants as it constitutes the force with which water is held by soil matrix (soil particles and pore space) and is measured by tensiometer.
What is matric potential of soil at field capacity? The water content of the soil at field capacity defines the upper limit of the plant available water or drained upper limit. It roughly corresponds to a matric potential of -30 kPa (-0.3 bars) in most soils and to -10 kPa (-0.1 bars) in sandy soils.
In what conditions soil matric potential is positive? As noted, we use the tensiometer to measure matric potential. A matric potential exists in soil when the soil is unsaturated and the water in the soil is under tension. We use a piezometer to measure water in saturated soil.
