A soil pH level of 4.5 is described as which of the following?

• A. Neutral
• B. Very acidic
• C. Basic
• D. Alkaline

Answer: (B)

Soil pH describes how acidic or basic the soil is and how that affects nutrient availability for plants. The scale runs from 0 to 14, with 7 as neutral; below 7 is acidic and above 7 is basic/alkaline. A pH of 4.5 sits well below 7, placing the soil in the acidic range and, given how far it is from neutral, it is described as very acidic. Neutral would be around 7, and basic/alkaline would be above 7. This level of acidity influences which nutrients are available to plants and can affect their growth, which is why 4.5 is categorized as very acidic.
