Question

Quizplus · Accepted Answer

By reducing the amount of fertilizer leaving the farm fields through no-till cultivation or other soil conservation techniques, there will be less fertilizers reaching streams or rivers, reducing the pollution caused by agricultural fertilizer runoff. Treating the contaminated water before it reaches streams or rivers could be effective for wastewater from urban areas, but it is not a practical solution for large-scale agricultural runoff. Adding chemicals to neutralize the fertilizers or raising crops in the rivers and streams that use the fertilizers are not viable solutions either.
