In this paper,we used the SmartChem140 Automatic Chemistry Analyzer method to determine total nitrogen(TN)and total phosphorus(TP)in the soil samples in Jiaozhou Bay wetland.The method can quickly and accurately determine TN and TP in the soil.The linear ranges of TN and TP were 0-6mg·L-1 and 0-5mg·L-1 with the correlation coefficients(R2)of 0.9994 and 0.9995,respectively.There were no significant difference between determination results of the method and those of the traditional kjeldah method and the Phos...
