| 摘 要： | 利用阿曼苏丹国的一千多个土壤样品,对土壤中碳酸钙和有机碳测定的实验方法进行了研究。发现实际碳酸钙的含量可由“亚稳态”时碳酸钙含量乘以适当的因子代替,从而大大提高了工作效率。而利用有机碳/全氮(C/N)的特殊规律,则可建立一个确定“有机碳”实验中所需土壤样品量的新方法。

| Abstract: | Studies the method of determining the content of CaCO_3 and organic carbonin the soil through the analysis of about one thousand soil samples, The percen-tage of CaCO_3 in the soil can be described as the percentage of its productobtained from "pseudo steady state" and appropriate factor. A new method canbe used to decide the quantity of the soil needed in the organic carbon analysistaking advantage of the characteristic of C/N. |
