Soil chemical and microbial effects of simulated acid rain on clover and soft chess

Effects of simulated acid rain on soil respiration rate and soil bacterial diversity in aPhyllostachyspubescensforest in subtropical China

“…Anderson and Domsch[35] also found that the total microbial biomass was more sensitive to acidic pH than to a neutral pH. Besides, McColl and Firestone [36] and Stemmer et al [37] observed that acid rain hardly impacted bacterial community in soil. In contrast, Pennanen et al [38] showed that the bacteria in soil microbial community would increase when humus pH was decreased and the bacteria in soil could adapt to the new acidic environment step by step.…”

Impact of simulated acid rain on soil microbial community function in Masson pine seedlings

“…Soil microbial activity has been found to be either reduced [1,8], stimulated [11], or unaffected [5,13] after being subjected to simulated acid rain. The present study showed that a low acid load not only stimulated soil microbial activity (expressed as AWCD) but also increased soil microbial community functional diversity and richness indices.…”

“…Therefore, soil microorganisms play a key role in maintaining the fertility of terrestrial habitats, and it can be inferred that factors that alter the rates of microbial processes in soil may influence forest ecosystem functions such as C sequestration. Acidic loads applied during a short time period, sometimes even in a single load, have been shown to have toxic effects on the soil respiration rate, microbial community structure, and microbial biomass [1,5,6]. Both direct and indirect effects of an increased acid load on the size, composition, and activity of the soil microbes have been reported [1,5,7,8,9,10,11,12,13].…”

Accompanying its rapid economic development and population growth, China is the world's third largest acid rain region, following Europe and North America [14].…”
