Compatible measurements of volumetric soil water content using a neutron probeand Diviner 2000 after field calibration.

摘要

Field calibrations for a neutron probe and a capacitance sensor (Diviner 2000)for measuring the soil water content of a shrinking–swelling clay soil weresubstantially different from commonly used default values. Using our fieldcalibrations, the two instruments estimated similar changes in the cumulativewater content of a soil profile (0–1 m depth) over one growing sea
