How many classes of soil texture are there?

• A. 10
• B. 8
• C. 12
• D. 15

Answer: (C)

Soil texture is categorized based on the size of the soil particles, which influence its physical properties and behavior. The standard classification system recognizes twelve classes of soil texture, which include categories ranging from clay, silt, and sand, to various mixtures of these components such as sandy loam, loam, and clay loam. Understanding these twelve textures is essential for landscapers and horticulturists, as it directly affects water retention, nutrient availability, and drainage characteristics of the soil. This knowledge is crucial for implementing efficient irrigation practices and sustainable landscaping designs.

The other numbers fall short or exceed the recognized classifications, emphasizing the importance of familiarity with the twelve distinct soil textures in water-efficient landscaping practices.
