Soils developed in forest settings tend to be more acidic than those developed in grasslands. This statement is:

• A. True
• B. False
• C. Not sure
• D. Sometimes

Answer: (A)

Soil acidity is shaped by what the vegetation puts into the soil and how it changes after death. Forest litter, especially from needles and other acidic plant material, tends to decompose slowly and release organic acids and hydrogen ions. At the same time, heavy rainfall common in forested areas leaches away basic cations like calcium, magnesium, and potassium, which leaves the soil more acidic. Grasslands, on the other hand, produce litter that is less acidic and decomposes more quickly, returning base cations to the soil and helping maintain a higher pH. So, under similar climate and parent material, forest soils generally become more acidic than grassland soils. There are exceptions in settings with unusual rock types or moisture regimes, but the overall trend holds.
