Assess students' ability to apply the Universal Soil Loss Equation (A = R·K·LS·C·P) to a specified agricultural field: calculate annual soil loss using provided R, K, LS, C and P values; compare the result to a tolerable soil-loss threshold; and recommend appropriate erosion-control practices (with justification of how each practice changes C and/or P and an estimated reduction in A). Expect stated assumptions, brief implementation/monitoring steps, and concise reasoning linking field conditions (soil texture, slope, crop/management) to chosen practices.
