Which statement best describes a boreal forest soil?

• A. Alkaline and nutrient-rich.
• B. Saline.
• C. Acidic and nutrient-poor.
• D. Neutral pH but nutrient-rich.

Answer: (C)

Boreal forest soils are formed under cold, humid conditions with mostly conifer litter, so decomposition is slow and organic acids accumulate. This drives the soil toward acidity, while bases like calcium and magnesium are leached away, leaving a mineral soil that is low in available nutrients. An organic-rich surface layer can exist, but the overall mineral nutrient supply remains limited because decomposition and nutrient release are gradual in the cold. This combination—acidic pH with low nutrient availability—fits boreal soils best, unlike alkaline or saline soils or neutral, nutrient-rich soils that occur in different climates or with different vegetation.
