Abstract: Soil acidification is a slow process under natural conditions, but it has been accelerated to some extent in the recent decades by anthropogenic activities, with a series of negative effects. We should pay more attention to the accelerated soil acidification. Here, we first reviewed the processes of soil acidification under both natural and anthropogenic conditions, and explored their driving factors such as soil base saturation percentage, acid buffering capability, acid deposit, fertilizers, plants, and land use management. Then, we summarized the ecological effects of soil acidification, including inhibited plant growth, altered soil biological community, increased soil heavy metal availability, and decreased water quality. Finally, sustainable strategies for acidic soil use were discussed from the two aspects, acid soil amendment and plant genetic modification. We proposed the future research trends in soil acidification.
