Question

Which is the most prevalent source of agricultural water pollution
Nutrients
Sedimentation
Pesticides
Irrigation

Answer 1

The most prevalent source of agricultural water pollution is typically **nutrients**, particularly nitrogen and phosphorus. These nutrients often come from fertilizers and animal manure used in agricultural practices. When they run off into water bodies, they can lead to issues such as eutrophication, which causes harmful algal blooms and depletes oxygen in the water, severely affecting aquatic ecosystems.

While sedimentation and pesticides are significant contributors to agricultural water pollution, nutrient pollution is generally considered the most widespread issue.
