Alkaline soil
Soil testing. A pH meter showing the alkalinity of soil. Farmers and gardeners use pH meters to determine the pH level of 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 on the pH scale. A pH of 7 is neutral, above 7 is alkali and below 7 is acid. This meter displays a pH of 7-8, meaning that this is an alkaline soil. Some plants are intolerant of alkaline soils, and so corrective procedures may be necessary to decrease the soil pH to make it more suitable. For images showing pH tests for acid and neutral soils, see E770/1091 and E770/1092

EDITORS COMMENTS
This print captures the process of soil testing, specifically focusing on the alkalinity of soil. In the image, a pH meter is prominently displayed, showcasing its importance in determining the pH level of soil for farmers and gardeners. The device works by measuring the amount of free hydrogen ions present in the soil, providing a value on the pH scale. The meter in this photograph reveals a reading between 7-8, indicating that this particular soil is alkaline. While some plants thrive in such conditions, others may struggle to grow. Therefore, corrective procedures might be necessary to decrease the soil's pH and make it more suitable for certain plant species. The significance of this image lies not only in its depiction of an essential tool used by agricultural professionals but also highlights how technology has revolutionized farming practices. With mechanized devices like this pH meter, farmers can efficiently analyze their land use and ensure optimal conditions for crop growth. Located outdoors amidst nature's beauty, this print showcases both scientific experimentation and environmental harmony. It serves as a reminder that understanding our surroundings through careful analysis is crucial for successful agriculture and horticulture practices.
