Question

In the Universal Soil Loss equation, factor K refers to:

• A. Erosivity factor
• B. Length of slope factor
• C. Conservation practices factor
• D. Erodibility factor

Hint:

USLE factors:
R - Rainfall, K - Soil, L - Length, S - Slope, C - Cover, P - Practice.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
Universal Soil Loss Equation (USLE) is used to predict soil erosion.
It has several factors.

Step 2: Key Formula or Approach:
USLE: A = R \(\times\) K \(\times\) L \(\times\) S \(\times\) C \(\times\) P.

Step 3: Detailed Explanation:
A = Soil loss.
R = Rainfall erosivity factor.
K = Soil erodibility factor.
L = Length of slope factor.
S = Slope steepness factor.
C = Cover management factor.
P = Conservation practices factor.
Thus, factor K is the soil erodibility factor.

Step 4: Final Answer:
Factor K refers to the erodibility factor.
Hence, the correct option is (D).
