摘要：

An effective field measurement of the air-entry and water-entry soil water pressure heads gives an improved description of the hydraulic properties of soils. One study obtained measurements of air-entry soil water pressure heads using a modified falling head infiltrometer. This study then estimated the value of the water-entry soils water pressure head from this value. Now direct field measurements of both the air-entry and water-entry soils water pressure heads can be easily obtained using an external tension bottle attached to the Guelph Pressure Infiltrometer at the conclusion of quasi-steady state infiltration readings.
