Which outcome arises when prolonged use of terrace farming leads to reduced soil organic matter?

💡 Explanation

When terrace farming continuously depletes soil organic matter, breakdown of soil aggregates occur because organic matter acts as structural binder, leading to less stable soil. Therefore a decline of structural stability results, rather than improved infiltration, nutrient capacity, or aeration, which depend on healthy soil structure.
