Abstract
Since 1982, I have been investigating the effects of atmospheric environmental stresses on plants with my supervisors, colleagues and students of Izuta Laboratory at Faculty of Agriculture, Tokyo University of Agriculture and Technology. In this memorial review of the academic award in 2015 from the Japan Society for Atmospheric Environment, I reviewed the results of our experimental studies on the effects of ozone, soil acidification and excessive soil nitrogen due to acid deposition and aerosol (black carbon and ammonium sulfate particles) on growth, physiological functions such as photosynthesis and nutrient and water status of Japanese crops and forest tree species.
