Abstract:Soil moisture of different layers was measured by improved L520 Neutronscope made in China and calibrated with polinomial regression method. The results show that measurments with new instrument and curve calibration method are much more accurate than that of the old LNW 50C Neutronscope and the linear calibration method.
