Simulated Acid Rain Threatens Soil Nutrient Movement, Impacting Crop Growth
The study looked at how acid rain affects the movement of nutrients in soil. Acid rain with pH 2.0 lowered soil pH a lot, while pH 4.0 and 6.0 had less impact. Different types of soil reacted differently to acid rain. Calcium, magnesium, and potassium were leached from the soil in that order. In sandy loam and loam soil, magnesium moved the most, followed by calcium and potassium. In clay loam soil, calcium moved the most, followed by magnesium and potassium. As the acidity of the acid rain increased, phosphorus moved slightly downward in the soil.
