Which of the following is false?
A. Fertilizers can maintain soil fertility and productivity into the distant future-even if the soil is eroding.
B. Soil erosion is occurring throughout most of the densely inhabited regions of the world.
C. Both the direct and indirect costs of soil erosion is estimated at hundreds of billions of dollars worldwide.
D. Soil that has eroded could take centuries to be replaced.
E. Loss of soil, combined with exponential population growth, could lead to serious food shortages.

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
