2. Background Farmers wish to increase crop growth per area of land
To increase soil fertility, fertilizer is applied to soil
Due to rain events or usual settlement, nutrients (phosphorus) are separated from soil
Farmers are losing a paid resource

3. Background Irrigation distributes water deposits evenly across land
Tile drain are basically designed to facilitate removal of excess water to reduce erosion and runoff of soil

4. Goals of Project
Manufacture functionalized media for selective removal of phosphorous.
Protect water resources from highly concentrated nutrients in farm runoff, which causes algae production and eutrophication.
Recover nutrients adsorbed by the media.
Restore adsorption capacity of the media for reuse.
Reduce monetary waste by returning recovered nutrients to the farmer.
Spread social awareness of phosphorus pollution from farms, and encourage implementation of regulatory standards to control its effects.

5. Circular Economy Farmer adds nutrients to soil
Nutrients separate from soil
Nutrients enter drain system
Nutrients are filtered out of flow
Nutrients are desorbed and collected
Nutrients are returned to farmer

6. Adsorbent Material
Adsorption is an effective method given this situation
Cost-efficient
On principle, there is a separation between adsorbent and pollutants filtered
For selective removal of phosphorous an adsorbent materials is functionalized by a metal oxide

7. Future
Transition from lab-scale to pilot-scale and finally full-scale fabrication
fabrication of a full-scale apparatus and the coordination with local farmers to test the system in the field, while addressing farmers' concerns
This new technology has shown to be an effective method of Phosphorus removal and is well on the way to becoming a revolutionary approach to pollution control as it relates to agriculture.
