Fertilizer rnoff can kill fish by darkenning the water and not allowing sunlight to come through. If sunllight can not come through, SAV's(Submerged Aquatic Vegitation) dies. Most fish eat SAV"s. If the primary source of fish food is dead, the fish die too.
it is polluting our lakes and rivers
Chemical runoff in an agricultural context is when farming chemicals, such as fertilizer are not absorbed into the topsoil. When a heavy rain comes, these chemicals are caught in the storm water runoff and make their way into streams, rivers, and lakes.
Run off
Into lakes,streams, and rivers
The accumulation of nitrogen and phosphorus from fertilizer runoff can lead to eutrophication, a process that causes excessive growth of algae in lakes and ponds. This algal bloom reduces oxygen levels in the water, harming aquatic life and disrupting ecosystems. Additionally, some algae produce toxins that can contaminate drinking water and harm wildlife. Ultimately, this imbalance can lead to dead zones where few organisms can survive, diminishing biodiversity and water quality.
An example of agricultural runoff is the excess fertilizer and pesticides that wash off fields during rainstorms or irrigation. This runoff can carry harmful nutrients like nitrogen and phosphorus into nearby rivers and lakes, leading to issues such as algal blooms and water pollution. These blooms can deplete oxygen in the water, harming aquatic life and disrupting ecosystems.
Some lakes do
Freshwater bodies like lakes and streams are generally more sensitive to the effects of fertilizer runoff compared to saltwater bodies like oceans. This is because freshwater ecosystems have lower buffering capacity and can be more easily disrupted by excess nutrients, leading to issues like algal blooms and low oxygen levels.
