This study was examined the EM's efficiency with growth and quality of seedling in Taiwan. Data were collected the 1 year of seedlings form the main afforestation green tree including Koelreuteria formosana Hay., Zelkova serrata Thunb., Acacia confusa Merr. and Fraxinus insularis Hemsl, and used the treatment with EM and Bokashi to improve the chemical characteristics of soil. The results showed that BE treatment was efficiency with net height growth, net root collar diameter growth, total dry weight, leaf area, leaf number, chlorophyll concentrations and N, P, K, Ca, Mg element content. The BE treatment was also efficiency the chemical characteristics of soil.
