This study focuses on energy dispersive X-ray fluorescence determination of minor and major elements in selected soils of Mambilla Plateau. The 12 sampled soil composites analysed were done by energy dispersive X-ray fluorescence technique for minor and major elements. The elemental oxides determined were Al 2 O 3 , CaO, K 2 O, TiO 2 , SiO 2 , BaO, Fe 2 O 3 , and MnO. The result obtained in the study showed that the general percentage concentration of elemental values were in decreased order of Si>Al>Ti>K>Ca for major elements and Fe>Mn>Ba minor elements accordingly. The major elements category showed silicon as the highest mean concentration at location S 84.09%±6.40 and calcium lower mean concentration with value of 0.32%±0.02. The minor elements concentration percentage revealed Fe with a mean value at location N 23.18%±3.1 being the highest and Ba is the lowest at location S 0.14%±0.1. The soil analysis revealed low concentration of essential major and minor elements, however, high concentration of Al and Fe that may solubilized at low pH and splitting H + from water molecule showed increased soil acidity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
