A study using soil columns was undertaken to examine the effect of acid precipitation on selected microbial processes. Following short-term (92 d) exposure of soil cores to acid rain at pH 3.7 and 3.0, no alteration in enzyme activities was observed. The effect on soil respiration was dependent on soil type. Dinitrogen fixation was reduced only in one of the soils by the rain of pH 3.0. Following long-term (690 d) exposure to acid rain, alterations in enzyme activities and CO/sub 2/ evolution were dependent on the soil type. No reduction in adenosine triphosphate (ATP) content of N/sub 2/ fixation were observed.
