What does a soil pH of 6.5 indicate?

A soil pH of 6.5 is considered moderately acidic. The pH scale ranges from 0 to 14, with a value of 7 being neutral. Values below 7 indicate increasing acidity, while values above 7 indicate alkalinity. A pH of 6.5 is just below the neutral mark, reflecting a slightly acidic condition that is still suitable for many crops.

Soils at this pH level can provide a good balance of nutrient availability for plant growth. Certain nutrients, such as phosphorus and potassium, are more readily available to plants in slightly acidic to neutral soils. Therefore, a pH of 6.5 is often seen as optimal for many agricultural crops, facilitating healthy growth and maximizing potential yields. Understanding soil pH is crucial for effective soil management and crop production.
