Assess students' ability to apply the Universal Soil Loss Equation (USLE) to estimate annual sheet-and-rill soil erosion for an agricultural field given rainfall intensity/rainfall energy data, soil texture and organic matter (to determine K), slope length and steepness (LS), crop/cover management (C), and conservation practices (P). Tasks include calculating each factor (with any necessary unit conversions), computing A = R·K·LS·C·P (expressed in t/ha/yr), interpreting the result, comparing alternative crop or practice scenarios, and recommending targeted conservation measures based on sensitivity of A to factor changes.
