Available microelements of 200 soil samples taken from tobacco soils in Southwest Sichuan were measured. Distribution patterns of their contents were discussed. The results show that in the tobacco soils in Southwest Sichuan, available Cu, Fe, and Mn are quite rich. Most of the soils are deficient in available Zn. The whole tobacco region is extremely low inavailable B. The findings of the research can be used as guidelines for optimal fertilization of tobacco.
