===Nutrients===
==Overview==
Improvements in the quality of stormwater runoff is one of the primary benefits of low impact development strategies. Although some chemical changes occur inside the practices, much of the pollution reduction of low impact development strategies comes from runoff reduction. i.e. diverting excess water through [[infiltration]] or [[evapotranspiration]].
==Nutrients==
Plants (including algae) require three macro nutrients to grow: Nitrogen, potassium, and phosphorus. Of these three, phosphorus is the often the "growth-limiting" nutrient. i.e. the local environment may have an abundance of nitrogen and potassium, but algae won't develop unless phosphorus is available too.
