Acid rain induced disturbances in nitrogen cycling within subtropical soil in China: toward preservation/restoration through elucidation of current state, mechanisms

Research grant

Project Description

Within the forests of China, acid rain has lead to excessive nitrogen intake into the soil, disturbing nitrogen cycling within it, producing large amounts of nitric acid and nitrous oxygen gas, and contributing to catchment eutrification and atmospheric warming. Indeed, amid concerns of intensification and spreading throughout Southeast Asia, this situation has become an international issue. In our research, we elucidate the current state of and mechanism behind acid rain induced disturbances in soil nitrogen cycling and in the microorganisms that drive the cycle. We create a model to predict changes in the ecosystem amid an intensification/spreading of acid rain induced damage and build a scientific foundation on which to formulate policies for preservation/restoration.
