What term describes a soil with a pH value greater than 7.0?

• A. Alkaline Soil
• B. Acidic Soil
• C. Neutral Soil
• D. Calcareous Soil

Answer: (A)

When soil pH is above 7.0, the environment is described as alkaline. That basic condition is what the term “alkaline soil” captures—the soil has a higher pH than neutral, which affects nutrient availability and microbial activity. Calcareous soil often has high calcium carbonate and can be alkaline, but it’s a more specific descriptor about mineral content and isn’t defined solely by the pH being above 7. Acidic soil refers to pH below 7, and neutral soil is around pH 7. So the correct, general term for a soil with pH greater than 7.0 is alkaline soil.
