Phosphorus removal by calcined eggshell adsorbents from agricultural soil systems and application of the adsorbent as a P fertilizer

Our project will explore the use of calcinated eggshells to reduce phosphorus runoff from farms, and reuse of these eggshells as fertilizers. The intern will test these calcinated eggshells mixed with woodchips to see how well they can absorb phosphorus under different conditions. They will also study how the phosphorus is distributed in the soil before and after treatment. Additionally, we will check if the eggshells can be reused as a slow-release fertilizer. The project will evaluate phosphorus sources from soil runoff by applying measurements of oxygen isotopes of phosphate from water and soil samples. This research will help the partner organization by providing a cost-effective and sustainable method to reduce phosphorus management and improve agricultural practices.
