| Abstract: | Current standard method GB11957 - 1989 for determination of the content of humic acid in compound fertilizer of humic acid needs multisteps and is time consuming. In this paper, content of humic acid in compound fertilizer of humic acid is measured by volumetric method. The empirical likelihood is 0. 087%. No great difference exisited between the results obtained by our method and that obtained by the standard method. Methods reported here is simple, precise and accurate with satisfied result. |
