| Outline of Final Research Achievements |
Understanding fate and transport of nitrogen in soil is important to consider sustainable agriculture. We set soil columns under steady water flow with various flow rate, and investigated the distributions of water, ammonium- and nitrate- nitrogen, and ATP in the columns. We also performed evaporation experiment, and clarified the relationship between water flow rate and nitrification rate, as well as ATP.
