Which agricultural risk increases following prolonged loess erosion?

💡 Explanation

Decreased nutrient availability results because erosion selectively removes finer, nutrient-rich particles via aeolian processes, rather than leaving them concentrated; therefore soil fertility declines, rather than enhancing carbon stores, increasing drainage or preventing hardpan.
