We carry out a research into environmental measures for soil/water/atmosphere that would maintain the circulation loop around the soil in a sound state. We consider the results gained from field surveys and experiments logically, clarify mechanism of pollutant migration/accumulation and examine purification measures and pollution control measures.
- Pollutant migration/accumulation within the soil and measures against it: heavy metals, nutrient salts, detergents and others
We clarify the mechanism of pollutant migration/accumulation in the soil and consider pollution control measures. Moreover, we utilize the water purification ability of the soil and examine the technology for water purification. Cleaning measures using surfactant is examined for polluted soils, especially for soils contaminated by organic pollutant. - Global warming gas control from agricultural lands
We observe global warming gas, especially carbon dioxide, for its generation and migration phenomena and examine measures to control it. - Soil material movements on sloped farmlands
We clarify migration forms of water, solute and even the soil itself on sloped farmlands, and examine soil management methods directed towards stable production.
