What is the erosion percentage for severely eroded soil?

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

Answer: (C)

Severely eroded soil is defined by the extent to which the soil has lost its original surface and topsoil layer due to various erosive forces, such as water or wind. When we categorize soil erosion, different percentages are assigned to represent the severity of erosion. In this context, a severe erosion classification indicates that more than 75% of the original soil material has been eroded away. This significant loss can lead to nutrient depletion, reduced soil fertility, and compromised land productivity. Understanding this helps in recognizing the challenges associated with severely eroded soils, which often become less capable of supporting crops and other vegetation. The management practices needed to restore severely eroded soils are more intensive compared to those for soils with less erosion, underscoring the importance of accurately identifying the severity of erosion for effective land management.
