This paper makes a comparative analysis on ammonium acetate flame photometry and M3 method used for determining the quick-acting Potassium in soil. The research findings show that compared with ammonium acetate flame photometry, the M3 method, which is convenient and fast,can obtain stable results and good repeatability and reproducibility, and is suitable for the analysis of large batch of samples, and the results of determining quick-acting Potassium in soil by using conventional method and M3 method are in good agreement and have excellent correlation.
