Which two RUSLE factors are typically influenced by land management practices and site-specific factors?

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

Answer: (B)

In RUSLE, which two factors you can most directly shape with field actions and by tailoring the field to its conditions are the cover-management factor and the practice factor. The cover-management factor reflects how the soil surface is protected—through crop choices, residue management, tillage, and permanent vegetation. This changes with what you plant, how you maintain crop residues, and whether you use cover crops, mulches, or different tillage practices. The practice factor represents the effectiveness of erosion-control practices you implement, such as contour farming, strip cropping, terraces, or other engineering measures. These depend on the field’s site conditions (slope, length, layout) and the management plan you choose. In contrast, rainfall erosivity is driven by climate and rainfall patterns, not by field management, and soil erodibility and the slope factor are tied to inherent soil properties and terrain, respectively, though they may be influenced indirectly to some extent.
