Abstract:
This study was initiated by time domain reflectometry (TDR) for two soil types in uniform and layered profiles. Measurements were taken in the laboratory for a Hanford sandy loam (coarse-loamy), (Typic Xerorthent) and a Yolo clay loam (Typic Xerothent) soil, using a two-rod parallel with pulse transformer and a three-rod coaxial probe. The TDR data of both soils were successfully fitted to a four-component mixing model that includes bound and free water, the solid and gas phases. The presence of a wet layer above dry soil may cause difficulties in signal interpretation. -from Authors
