Which outcome occurs within Inca agricultural terracing given variable rainfall?

💡 Explanation

Increased soil nutrient leaching occurs when excessive rainfall saturates the terrace soil, causing downward movement via percolation; `preferential flow` is the mechanism by which this enrichment migrates elsewhere, because the gradient intensifies, therefore less available nutrition versus water loss; rather than slope failure.
