What factors are associated with the land capability subclass for erosion?

• A. Water or wind
• B. Organic matter and decomposition
• C. Soil pH levels
• D. Climate and temperature

Answer: (A)

The land capability subclass for erosion primarily focuses on the potential for soil erosion under various conditions, and this is closely linked to factors such as water and wind. These forces are significant in determining how susceptible a particular soil type is to erosion. Water erosion can occur through surface runoff, especially on slopes, while wind erosion is a concern in drier, sandy, or loose soils, particularly in areas that lack sufficient vegetative cover. Thus, assessing the impact of water and wind is essential for determining the subclass related to erosion, making this choice applicable and accurate in the context of soil management and conservation practices. Organic matter and decomposition, soil pH levels, and climate and temperature certainly influence soil characteristics and overall health, but they do not directly pertain to the assessment of erosion potential. Instead, they play more indirect roles in the overall soil ecosystem and its resilience against erosion.
