Readily available water in constant matric suction is more in

Readily available water in constant matric suction is more in sandy soil.
Matric suction or negative matric potential is the free energy change in a unit volume of water when isothermally transferred from the soil water state to the free water state.
Readily available water is the water that a plant can easily extract from the soil and its value is more when Matric suction is constant in the case of sandy soil as it cannot hold and absorb much water like other soils.
