What percentage of erosion characterizes moderately eroded soil?

What percentage of erosion characterizes moderately eroded soil?

• A. Less than 25%
• B. 25-75%
• C. More than 75%
• D. No erosion

Answer: (B)

Moderately eroded soil is characterized by a loss of 25% to 75% of the original topsoil, which is significant enough to affect soil health, nutrient availability, and the overall ecosystem. This range indicates that while the soil has experienced notable erosion, it still retains a substantial amount of its original productive topsoil layer. This understanding is crucial for soil management practices, as knowledge of the extent of erosion can guide conservation efforts to mitigate further degradation and enhance soil recovery. The other percentage ranges—less than 25% indicates minimal erosion, while more than 75% suggests severe erosion, and no erosion suggests that the soil is intact—do not align with the definition of moderately eroded soil.
