Phosphorus

Nutrient essential for plant and animal life.  Too much can cause large amounts of weeds and algae to grow, harming river health.

Increased phosphorus levels often come from runoff from pastures, crops and lawns that have been fertilised. Phosphorus is measured either as ‘total phosphorus’ (TP), or ‘dissolved reactive phosphorus’ (DRP).
