What factors are used for RUSLE

• A. R, K, LS, C, P
• B. R, P, S
• C. R, K, C
• D. K, LS, P

Answer: (A)

RUSLE estimates annual soil loss by multiplying five factors that represent different controls on erosion: rainfall erosivity (R), soil erodibility (K), the effect of slope length and steepness (LS), cover-management (C), and support practices (P). The equation is A = R × K × LS × C × P, so the combination of these five factors is what the correct option lists. R captures how hard rainfall hits the soil, K describes how easily soil can be eroded, LS accounts for how slope geometry influences runoff energy, C reflects how vegetation and residue protect soil, and P includes practices like contouring or terracing that reduce erosion. Missing any of these factors would leave out a key control on erosion, making the option incomplete.
