  2. What is phosphorus? Phosphorus powder • Phosphorus is the 15th element on the periodic table, represented by the letter “P”. • When pure it is colorless and transparent. • Phosphorus was discovered in 1669 by Brand, who prepared it from urine. Brand attempted to distill salts by evaporating urine.

  3. Where can you find phosphorus? • Fertilizers • Animal effluent (Feces/Urine) • Natural weathering of rocks (basically erosion!)

  4. Cycle!

  5. How does it affect water ways? • Phosphorus binds with soil and only dissolves slowly in water overtime. • These can include: Erosion Farm runoff (fertilizer) • Phosphorus “starves” streams of oxygen, thus affecting aquatic life in a negative manner.

  6. Ways to Manage Phosphorus in waterways. Prevent direct application of fertilizer to waterways by: • Controlling runoff before it reaches the water. • Avoiding applying phosphate fertilizer if you know heavy rain is coming. • Trying to prevent overgrazing that can ultimately lead to erosion.

  7. Benefits for humans • Phosphorus is a mineral mostly stored in your bones, teeth, DNA and cell membranes. • It is important for many biochemical reactions such as converting the foods you eat into the energy your body needs every day. • Phosphorus also helps with muscle contraction, nerve and kidney functions.

  8. fun facts: • We must have phosphorus to live! • Holds DNA and RNA together • Chemical component for ATP • 80% of phosphorus is found in teeth in bones • Largest reservoir of phosphorus is in sedimentary rocks • Phosphorus in waterways encourage the growth of nuisance aquatic plants/algae.
