英文摘要	Nitrate leaching from intermittently flooded rice fields contributes to nitrate pollution in groundwater. In this study, redox conditions and nitrate change in a newly flooded rice soil under the influence of oxidative iron (Fe) and manganese (Mn) were investigated using flooded soil columns under moderate percolation (4.2 mm d(-1)). The amendments of alpha-Fe(2)O(3) and beta-MnO(2) powder (5 and 2.7 mg g(-1), respectively) delayed the establishment of reducing conditions and lowered the rate of nitrate removal in the soil column, and subsequently increased the percolation of soil indigenous nitrate (8.3 mg nitrogen [N] kg(-1)) from 2.0% to 8.0%, and the percolation of externally amended nitrate (250 mg N kg(-1)) from 11.0% to 26.0%. The pool of oxidative iron-centered metal oxidants needs to be jointly considered with the availability of organic carbon and hydrological conditions in evaluating redox conditions and nitrate change in intermittently flooded rice soils.
