Normal soil
Soil testing. A pH meter testing the acidity or alkalinity of soil. Farmers and gardeners use pH meters to determine the level of acidity in soil to assess its suitability for different plants. A probe placed in the soil measures the amount of free hydrogen ions present, giving a value of acidity on a pH scale. A pH of 7 is neutral, above 7 is alkali and below 7 is acid. This meter displays a pH of 6, meaning that this is a normal (close to neutral pH) soil. For acid and alkaline soils, see E770/1091 and E770/1156

EDITORS COMMENTS
This print showcases the process of soil testing using a pH meter. Farmers and gardeners rely on this technology to determine the acidity or alkalinity level of soil, which helps them assess its suitability for different plants. The probe inserted into the soil measures the presence of free hydrogen ions, providing an accurate value on the pH scale. In this particular image, we observe a pH reading of 6, indicating that this is normal soil with a close-to-neutral pH. The significance of such measurements lies in their ability to guide agricultural practices and land use decisions. Acidic or alkaline soils require specific treatments and amendments to create optimal conditions for plant growth. By utilizing these analytical tools, farmers can ensure that their crops thrive in an environment conducive to their needs. This photograph not only highlights the technological advancements in agriculture but also emphasizes our growing understanding of how different factors impact our natural surroundings. It serves as a reminder that scientific research plays a crucial role in shaping sustainable farming practices and preserving our delicate ecosystem.
