The carbon and nitrogen cycling model described with PHREEQC was linked with HYDRUS-1D using the HP1 code. Various nitrogen transport scenarios could be demonstrated for the application of organic matter to a variable-saturated soil under nonisothermal conditions. Furthermore, oxidation-reduction potential and dissolved oxygen were monitored in a ponded saturated paddy soil column to observe the formation of the surface oxidation layer and the reduced layer., 2011年度~2013年度科学研究費補助金(基盤研究(B))研究成果報告書, 23380140}, title = {土壌圏における水分・窒素・炭素統合循環モデルの構築}, year = {2014} }
