A Methodical Study on Soil Moisture Determination by the Neutron Scattering Method The use of the neutron scattering probe for the determination of soil moisture content in 60 plots in Dikopshof fertilisation experimental station for two years had required the study of some methodical aspects. One of the points is to get the standard curve. It was found that the standard curves taken from the model and from the field were nearly identical. Although regression analysis of the standard curve yield linear shapes, significance for non linear curves, was also obtained. The centre of sensitivity was more easily obtained by lowering the probe between two water filled containers than by the usual method.
