Phosphorus runoff: Phosphorus runoff refers to the movement of excess phosphorus from agricultural fields or other sources into nearby water bodies. It can lead to water pollution and harmful algal blooms.
Eutrophication:Eutrophication is the process by which a body of water becomes enriched with nutrients, often due to excessive inputs of nitrogen and phosphorus. This can result in excessive plant growth, oxygen depletion, and negative impacts on aquatic ecosystems.
Nitrogen fixation: Nitrogen fixation is the conversion of atmospheric nitrogen gas into a usable form by certain bacteria or through industrial processes. It is an important natural or artificial process that provides plants with the necessary nitrogen they need for growth.
