The input flux of Se in farmland soil of 9 counties in the middle east of Guangxi were studied. By integrating various factors, the authors took the atmospheric wet and dry depositions as the main input way of Se. The average atmospheric wet and dry deposition flux in the whole study area is 6.36 g/(hm2·a), the irrigation water input flux possesses the second position, whereas the fertilization input flux is obviously lower. They account for 70.93%,27.35% and 1.72% of Se in soil respectively. Their proportions are somewhat different among 9 counties of the study area: the contribution of the atmospheric wet and dry deposition is the highest, accounting for more than 50%. Therefore, the atmospheric wet and dry depositions seem to be the main input ways of Se in the study area. The regional differences of Se input flux and the proportion of different input routes in the study area are basically consistent with the total amount of As, Cd, Cr6+, Hg and Pb in the field soils. These data show that the inputs bring in not only the beneficial element Se but also a certain amount of heavy metals. Therefore, the pollution of heavy metals in soil caused by the inputs should be strictly prevented and controlled.
