Agricultural fields with excessive or ill-timed fertilization have been blamed for the spring-time release of phosphorus-laden waters into streams and large bodies of water. Several solutions to this problem are being investigated, including the use of soil amendments that can capture and retain phosphorus. In this adsorption study, rice hull, fish tank, wood pellet, wood chip, and Phragmites biochars were tested to determine their sorptive capacity for phosphorus in solution (SRP) and if mixing with soil in a 90% soil/10% biochar (w/w) ratio would increase SRP adsorption or retention. My hypothesis was that the Phragmites biochar would adsorb the most SRP due to having the largest surface area of the biochars. The biochars and soil reached adsorption equilibrium with phosphorus in solution in less than one hour. Rice hull biochar was the only biochar that adsorbed more SRP than soil and none of the biochars adsorbed more SRP than was initially contained in the sample. The rice hull data were characterized by an S-shaped isotherm, while the other biochar data did not fit any standard adsorption equations. Initial nutrient concentrations and pH influenced sorption more than surface area. Phragmites biochar adsorbed no SRP and therefore would not be a suitable adsorbent for SRP.
