The correct option is D All of the above

Soil pollution can be controlled by several factors. It includes the limited use of fertilizers and pesticides. The biological control method must be known and implemented. The grazing must be controlled and forest management should be done properly. The afforestation and reforestation must be done. In areas of wind erosion wind breaks and shields must be used. The soil binding grass must be planted and the large trees must be placed along the banks. The industrial wastes must be dumped in the low lying areas. There is a definite technique of cropping which does not allow the weeds to settle on the fields.

So, the correct answer is 'All of the above'.
