The recommended soil pH range for most vegetables is 6.2 to 6.8. If a soil test shows your garden soil to have a pH of 7.8, your garden soil is:

• A. Slightly alkaline
• B. Slightly acidic
• C. Neutral
• D. Can't tell from the soil test

Answer: (A)

Soil pH shows how acidic or alkaline the soil is, and most vegetables grow best in slightly acidic to near-neutral conditions, around 6.2 to 6.8. A pH of 7.8 sits above neutral (7.0) and falls into the alkaline side of the scale. Since it’s only a bit above neutral, it’s best described as slightly alkaline. When pH is higher than the preferred range, some nutrients become less available to plants (especially iron, manganese, and others), which can affect growth unless the pH is adjusted. If you want to bring the soil closer to the ideal vegetable range, you’d look at acidifying practices such as adding organic matter that lowers pH or targeted amendments like elemental sulfur over time.
