Answer:
Option A, Fertilizers can maintain soil fertility and productivity into the distant future-even if the soil is eroding.
Explanation:
The top layer of the soil known as top soil is essential for its productivity because it contains essential nutrients such as phosphorus and potassium.
If this topsoil is lost, the inherent soil fertility is also lost. In order to restore the soil fertility, additional inputs in the form of fertilizers and manures are used.
Fertilizers help in restoring soil fertility but only if the essential subsoil material are present. In short it can be said that continuous soil erosion for a longer period of time will result into infertile land parcels whose fertility cannot be restored by fertilizers.
Hence, option A is correct
