What is carried in the water that goes from feld?

Water that flows from fields often carries various substances, including nutrients like nitrogen and phosphorus from fertilizers, organic matter, and sediment. It may also contain pesticides, herbicides, and pathogens from agricultural practices. These constituents can impact water quality and ecosystems as the runoff enters nearby streams, rivers, or lakes. Proper management practices are essential to mitigate these effects and protect aquatic environments.
