Effects of Simulated Acid Rain on Soil Chemical Properties of Potting Yellow Cinnamon Soil under Quercus Variabilis

Article Preview

Abstract:

Acid rain pollution is a serious environmental problem in the world. This study investigated the impacts of simulated acid rain on yellow cinnamon soil planted with seedlings of Quercus variabilis. The results showed that the acidity of simulated acid rain had complex impacts on the organic matter content of the studied soil. With the decrease of the acidity, available K increased but soil pH reduced. Rainfall of simulated acid rain also had impacts on available K and the soil pH, and produced the same trend as the acidity. In conclusion, we estimated that high intensity and large rainfall of acid rain could affect soil properties.
