Extraction experiments were performed to estimate the effect of temperature of EGCG and citric acid on mobilization of Si, Al, Fe and Mn in Bleached Paddy Soil and Yellow Earth. The obtained data demonstrated that: the amount of Si, Al, Fe or Mn mobilized by EGCG or citric acid from 2 soils increased with increasing temperature overall, which indicated that both EGCG and citric acid can improve the amount of mineral elements mobilized, especially in the season of high temperature. At the same temperature, the comparisons among the amount of mobilized elements showed that EGCG or citric acid mobilized the decreasing amounts of mineral elements in the following order of Al＞Si＞Fe (Mn), indicating that Al was more easily mobilized than Si, Fe or Mn. The amounts of Fe mobilized by citric acid from 2 soils were larger than that of Mn, similarly, the amount of Fe mobilized by EGCG were also larger than that of Mn from Bleached Paddy Soil, while for Yellow Earth, the opposite phenomenon that EGCG mobilized more Mn than Fe was observed. Meanwhile, with regard to the 2 different soils, the amount of Al, Fe or Mn mobilized by EGCG or citric acid was always higher for Yellow Earth compared to the Bleached Paddy Soil, but the amount of Si mobilized was higher for Bleached Paddy Soil. Moreover, as far as EGCG and citric acid were concerned, citric acid was found to mobilize significantly more Si, Al or Fe than EGCG from 2 soils, suggesting that citric acid had stronger ability in mobilizing soil Si, Al and Fe.
