There is no significant difference between the result of the method and that of micro-Kjeldahl′s method according tot test. The relative standard deviation is 3.1%.
经t检验证明，该方法的测定结果与微量凯氏定氮法无显著差异，测定结果的相对标准偏差为3.1%。

The simulated test mainly simulates the basic situation of the farmland, determines the content of nitrogen in soil drench solution, and adopts semi-micro Macro Kjeldahl method.
模拟试验主要模拟农田的基本情况，测定土壤淋溶液中氮的含量，采用半微量开氏法。
