In this paper the contents of five microelements (Zn, Fe, Mn, Cu, B) and their relationship with other physico-chemical indices of three type soils at two yield-levels in Shandong Province were studied. Results showed that concentrations of five microelements were significantly different among different types of soils. In brown soil, B was deficient but Fe and Mn were sufficient. In soils studied available Fe content of high-yield fields was significantly higher than low-yield fields. The insufficient percentages of available Mn, Zn and B were 9%, 33% and 28% in high-yield fields, respectively.
