What is the characteristic of a soil sample with a pH value of 7.0?

A soil sample with a pH value of 7.0 is characterized as neutral. This means that the soil has an equal concentration of hydrogen ions (H+) and hydroxide ions (OH-), indicating a balanced state that is neither acidic nor alkaline. Soils with a pH below 7.0 are considered acidic, while those above 7.0 are classified as alkaline. Neutral soil is often ideal for a wide variety of plants since it typically allows for better nutrient availability and supporting healthy plant growth.

Understanding the implications of soil pH is crucial in horticulture, as it affects not only plant health but also the availability of essential nutrients in the soil.
