The work reported here focuses on the effects of acid deposition on nitrification, denitrification and N2 fixation associated with plant roots and nitrification and denitrification in surface soil. Simulated acid precipitation of pH 2.0, 3.0, 4.0 and 5.6 was employed. The purpose of the extreme treatments (pH 2.0 and 3) was not to directly simulate ambient rates but rather to identify thresholds at which effects may begin to occur. It was then attempted to assess whether these thresholds may be reached in natural terrestrial systems.
