An investigation on the contents of Fe in the surface soils of 150 Tieguanyin tea plantations in Anxi,Yongchun and Hua'an Counties in Fujian province as well as the transfer of the soil Fe into the tea leaves was conducted.The total contents of Fe in the soils ranged from 9.35 to 90.48 g•kg-1,with a mean of 32.33 g•kg-1.The available contents of Fe were between 9.20 to 395.11 mg•kg-1,with a mean of 57.11 mg•kg-1.The contents of Fe in the tea were between 19.77 to 797.47 mg•kg-1,with a mean of 126.71 mg•kg-1.The soil-to-tea leaves transfer factors of Fe positively correlated with the total or available Fe.
