Abstract
The phosphorus (P) cycle is not well understood. While carbon (C) and nitrogen (N) have gas phases, P does not. Phosphorus runoff in waterways and its shortage are both understood since their causes are due to agricultural demands. Fertilizers increase the rate of phosphorus in the soil leading to greater runoff which then accumulates in the surrounding bodies of water.1 From an economic perspective the phosphorus availability and food prices have a direct correlation. The instability of phosphate prices may have direct causation to the instability of the food and agriculture markets.2In order to deal with these issues, P transfer from sediment through soil must be understood. Fourier Transform Infrared Spectroscopy (FT-IR) and nuclear magnetic resonance imaging (NMR) will be used to analyze P compounds in soil.
My research will answer how phosphorus exchange occurs from sediment through soil.
Unlike C and N, P does not have a gas phase at atmospheric pressure which makes the exchange difficult to study. Information on the composition and dynamics of soil phosphorus (P) remains limited, but is integral to the understanding of soil biogeochemical cycles.3 This research will combine the analytical techniques of FT-IR and NMR to expand the knowledge of P in soil biogeochemistry. Furthermore FT-IR and NMR will allow for P species to be both identified and the amount in a sample to be calculated. Learning how P transfers from sediment through soil will both clarify how the P Cycle operates and yield foresight to agriculture markets.
