Question

The soil loss equation is:

• A. \(A=RKLSCP\)
• B. \(A=JKLSCP\)
• C. \(A=RKLJSCP\)
• D. \(A=LDPSC\)

Hint:

USLE is \(A=RKLSCP\), where \(R\) is erosivity and \(K\) is erodibility.

Answer 1

The Correct Option is A

Concept:
The Universal Soil Loss Equation is used to estimate average annual soil loss due to water erosion.

Step 1: Write the standard equation. \[ A=R\times K\times LS\times C\times P \]

Step 2: Meaning of symbols. \[ A=\text{average annual soil loss} \] \[ R=\text{rainfall erosivity factor} \] \[ K=\text{soil erodibility factor} \] \[ LS=\text{slope length and steepness factor} \] \[ C=\text{crop management factor} \] \[ P=\text{conservation practice factor} \]

Step 3: Match with option.
The given compact form is: \[ A=RKLSCP \] \[ \therefore \text{Correct Answer is (A)} \]
