| Outline of Final Research Achievements |
In order to increase the nutrient efficiency and prevent the soil water air contamination, we conducted experiments of adsorption and dispersion-flocculation, and survey of paddy fields. We also did application of theoretical analysis to evaluate the phenomena. We elucidated phosphate adsorption in kaolinite and its influence on Ferralsol dispersion-flocculation, Sr adsorption in clays and its restriction of transport in soils, and an anionic surfactant adsorption in highly humic soil. Fundamental method for desalination of Tsunami affected agricultural lands was proposed. Stock efficiency of carbon dioxide in paddy fields was evaluated.
