Simulated acid rain can affect the soil and plants. When soil is exposed to acid rain with a pH of 2.0, it can lead to changes in the soil that increase the uptake of certain minerals by soybean plants. This includes basic cations, manganese, zinc, and copper. Despite some changes in soil chemistry, the growth and yield of soybean plants were not significantly affected by the simulated acid rain treatments. Overall, the study shows that acid rain with a pH of 3.0 or below can alter soil conditions and mineral uptake by plants, but it did not have a major impact on soybean growth under normal farming practices.
