Abstract

Six bulk density sampling methods were evaluated for use in neutron gauge
calibration. All six methods provided estimates of bulk density which were
generally within 5% of bulk density profiles measured using a gamma probe.
Standard errors of estimate ranged from 3 to 7 %. When used with care,
downhole, coring, and drive samplers can be used to successfully measure soil
moisture and bulk density profiles for use in neutron probe calibration.
