A soil pH reading of 6 is considered which category?

• A. Neutral
• B. Slightly alkaline
• C. Slightly acidic
• D. Strongly acidic

Answer: (C)

Understanding soil pH categories helps explain nutrient availability. The pH scale ranges from acidic on the low end to alkaline on the high end, with 7.0 as neutral. A reading of 6 is below neutral, so it’s acidic, but not strongly so. In common gardening terms, 6.0 is described as slightly acidic. This means the soil is a bit acidic enough to influence certain nutrients without causing the more extreme effects seen at very low pH. It’s not neutral, and it’s not in the strongly acidic range. If you needed to adjust for plants that prefer neutral or alkaline conditions, you’d move the pH upward toward 7 or higher; to push toward stronger acidity you'd lower it further.
