Soil pollution is caused by:
Soil pollution due to acid rain occurs when these acidic materials, such as sulfuric and nitric acids, come into contact with the soil. This leads to an increase in the acidity of the soil, causing the pH levels to decrease. This makes it difficult for plants to thrive. The higher acidity levels cause the essential minerals such as calcium and magnesium to be washed away, making it difficult for plants to grow. The soil can also dissolve toxic materials such as aluminum, which can be absorbed by plants.
