| Abstract: | In this paper,conditions for determining effective potassium oxide contents in K-Ca fertilizer with flame photometry was investigated.Compared with sodium tetraphenylboron volumetric method,the results showed no distinct difference after F and t tests.Being of lower cost and faster,it may therefore be used as a routine method replacing the conventional volumetric analysis. |
