Which outcome reduces agricultural productivity when exposed loess sediment occurs?

💡 Explanation

Nutrient leaching accelerates because loess lacks a strong clay matrix creating high porosity; therefore nutrients quickly dissolve and wash away, depleting the soil, rather than being retained by structured aggregates as found in clay-rich soils.
