Abstract

Calibrating neutron depth gauges for measuring soil water content profiles requires
soil bulk density data. In this study, the feasibility of using a single probe gamma
density gauge to measure the soil wet bulk density was investigated for use in neutron
gauge calibration. The same sites, access tubes, and conventional gravimetric soil data
used for the ASCE Neutron Gauge Calibration Study were used for the Gamma Gauge
Study. Iterative procedures were successfully developed to calibrate the gamma
density gauge, and then to convert wet bulk density to dry bulk density data for the
three soil sites studied.
