Sign In Question: A soil sample indicating pH = 7.5, EC, = 4.8 ds/m, exchangeable sodium percentage = 12, may be categorized as which one of the following?
✅Explanation:
-Soil Classification: Soil classification is based on specific parameters such as pH, electrical conductivity (EC), and exchangeable sodium percentage (ESP).
-Saline Soil: Saline soils are characterized by a high concentration of soluble salts, typically with an EC value greater than 4 dS/m. The pH is usually less than 8.5, and the ESP is less than 15.
-Given Sample: The soil sample in question has an EC of 4.8 dS/m, indicating a high salt concentration. The pH of 7.5 is within the acceptable range, and the ESP of 12 is below 15. These characteristics align with the definition of a saline soil.
