Answer: Practicing conservation tillage
Explanation:
Conservation tillage is an agriculture practice. In this the soil is plowed up and down so as to make the soil texture loose, removes the compaction of the soil, improves the water holding capacity of the soil so that the water instead of flowing over the surface get absorbed by the soil. This practice will reduce pollution of the water source as the soil will absorb the water no surface runoff of materials such as agricultural fertilizers and pesticides into the water source. Hence, the pollution will be prevented.
