Abstract

The portable surface capacitance insertion probe was used to measure the in situ water content of near surface soil layers. The probe readings were calibrated against gravimetric samples collected over a wide range of water contents, and were found to be very closely correlated. The capacitance probe was used repeatedly in time and space at a field site where ridges and furrows ensured a regular pattern of soil water variations. The observed spatial variations of the water content were related to topography and land mangement. The degree of variability was dependent on the average water content.

The calibration of a capacitance sensor (operating at 80-150 MHz) for monitoring soil water content is described. The capacitance of two electrodes inserted into soil is used to measure the dielectric properties of the soil, soil water content being the principal factor influencing these properties.

## Abstract Time‐domain reflectometry (TDR) is increasingly used for field soil water estimation because the measurement is non‐destructive and less affected by soil texture, bulk density and temperature. However, with the increase in instrument resolution, the influences of soil bulk density and t

## Abstract Time‐domain reflectometry (TDR) sensors have been widely used in many fields for measurement of soil water content. However, few TDR sensors have been used in a hyper‐arid environment (e.g. less than 0·05 m^3^ m^−3^), and such sensor applicability is not yet confirmed. In this study we
