Phosphorus removal bed at the Blanchard River Demonstration Farms Network. Phosphorus removal beds are ideally placed in sites with known excess dissolved phosphorus issues. Fields that have higher soil test phosphorus readings have an increased likelihood to leak that phosphorus into downstream bodies of water.

This steel slag binds the phosphorus and removes it from the water.
