Excess phosphates and nitrates from fertilizer runoff cause harmful algal blooms through eutrophication, impacting aquatic ecosystems.
Phosphates and Nitrates, as major sources of pollution in waterways from excess fertilizer runoff, lead to algal blooms in lakes and rivers, a process known as eutrophication. These excess nutrients fuel rapid algae growth, which, upon dying and decomposing, deplete oxygen levels, causing harm to aquatic life.
