Field Comparison of Soil Moisture Sensing Using Neutron
Akhtar Bhatti, M. Use of neutron soil moisture probe to determine water distribution uniformity in furrow irrigation. Int. Symp. on Isotope & Radiation Tech. in Soil Physics and Irrigation Studies, Aix en Provence, IAEA Vienna, 1983.... A neutron probe contains a pellet of americium and beryllium, whereby the alpha particles from americium collide with the beryllium nuclei. Consequently, the detection of the slow neutrons will allow the probe to detect the amount of hydrogen that is present within the soil.

How To Use Neutron Probe
Abstract : The objective of this study was to determine the unsaturated hydraulic conductivity, using a neutron probe, of a clay sandy Oxisol. The study was carried out in the city of Piracicaba, State of São Paulo, Brazil (22°42′43.3″S, 47°37′10.4″W, 546 m).
