Various methods for assessing soil totalnitrogen(N)have been developed to manage N nutrient and to understandN cycle in soil.Kjeldahl distillation -titration(KDT)has been used widely as a reference method for N determination insoils，but it is time consuming method.The objective is aimed at establishing a time saving method for determining ofsoil total N by a continuous flow analyzer(CFA).Fifty soil samples and two standard samples were digested with H 2SO4catalysts(K2SO4∶CuSO4∶Se=100∶10∶1).N contents in the digests were determined by a CFA and an automated KDTinstrument，respectively.The result of t test found that there was no any significant difference of the soil contents measuredby the CFA and the KDT method.A significant linear correlation could best describe the measured N values measuredby bothmethods:Y(CFA -N)=0.9951X(KDT -N)+0.0035.The pearson ’s correlation coefficient was 0.980 with asignificancelevel(n=50， P<0.01).The CFA method for soil N measurement had a high precision with relative standarddeviation(RSD)less than5%.It is suggested that the CFA based on colorimetric detection of the pure ammonium chloridedistillate(Berthelotreaction)can be used to determinate N in the Kjeldahl digests of soilsamples.The CFA method is laborsaving and can handle large numbers ofsamples.
