How does composting reduce eutrophication?
Because compost helps bind nutrients chemically it prevents them from leaching into groundwater. … While obviously good for the plants this also reduces the amount of nutrients that will pollute air or water.
How does agricultural waste lead to eutrophication?
Agricultural waste is a main cause of this because that waste contains many chemical fertilisers in it which were used before in the fields for plants growth . These fertilisers contain specific amount of nitrogen and phosphorous and when these run off on the surface and joins water source they lead to eutrophication.
How does agricultural runoff affect humans?
