The study looked at how different types of acid rain affect the leaching of aluminum, cations, and anions in reclaimed saline soils. They used simulated acid rain with varying nitrate-to-sulfate ratios on soils from Korea and Japan. The results showed that the leaching of cations and anions in two soils didn't change much with different acid rain compositions. However, in the third soil, the leaching increased as the nitrate content in the acid rain increased. Additionally, the leaching of aluminum in the soils increased with higher nitrate content in the acid rain.
