Abstract:
Surface neutron-gamma gauges are handy instruments to measure soil water contents and bulk densities of surface layers. Although available for some decades, their optimal use is still not well established. This study is a contribution to improve their use, mainly in relation to calibration, and of the effect of soil dry bulk density on soil water content measurements.
