    Fall 2017 Semesterly Report Submitted to the Student Sustainability Committee (SSC)


Subsurface (tile) drainage has helped to sustain the productivity of our farm lands by draining excess water from the field. Excess nutrient losses from our tile-drained agricultural fields have contributed to several water quality issues in the region including the formation of hypoxic zone in the Gulf of Mexico. It has been well-documented that tile drainage is responsible for highly soluble nitrate loss but recent studies have demonstrated that it also contributes to dissolved phosphorus loss from the agricultural fields.

This project aims to develop ceramic pellets using fly ash and other additives with minimum or no heavy metal leaching. The specific objectives of this proposed research project are to: a) optimize the proportion of fly ash and other additives for high phosphorous removal and limit heavy metal leaching, b) conduct laboratory experiments to analyze the performance of pellet for dissolved phosphorous reduction.



This is a Student Sustainability Committee supported project.
