Why is poor quality soil a problem?

Soil degradation leads directly to water pollution by sediments and attached agricultural chemicals from eroded fields. Soil degradation indirectly causes water pollution by increasing the erosive power of runoff and by reducing the soil’s ability to hold or immobilize nutrients and pesticides.
