“…There is also a slight downward trend of the PZNPC with increasing temperature, from pH 7.80 at 25 • C to 7.61 and 7.56 at 50 and 70 • C. This trend has been observed for other phyllosilicates and oxides [49,50] for kaolinite and simple oxides: [51] for magnetite; [52,53] for silica and alumina; [54] for γ -Al 2 O 3 ; [55,56] as a Table 4 Fitted equations for the PZNPC dependence with the ionic strength for different studies ( [11,15] and this study).…”

“…Log K w is −14.00 at 25 • C, and −13.26 and −12.80 at 50 and 70 • C [28]. Following the approach of [49] and correcting C to 1.81 F m −2 at 50 • C and C to 1.92 F m −2 at 70 • C allows the temperature effect on the electrostatic term in Eqs. (1)-(3) be approximated.…”

“…Angove et al . (,b) concluded that for two adsorbents commonly found in soil (Goethite and Kaolinite), adsorption of mellitic acid was accompanied by a strong increase in entropy. Increases in entropy can be important enough to offset the endothermic nature of some adsorption reactions, resulting in reactions that are spontaneous and endothermic.…”

The response of soil organic matter (OM) decomposition to increasing temperature is a critical aspect of ecosystem responses to global change. The impacts of climate warming on decomposition dynamics have not been resolved due to apparently contradictory results from field and lab experiments, most of which has focused on labile carbon with short turnover times. But the majority of total soil carbon stocks are comprised of organic carbon with turnover times of decades to centuries. Understanding the response of these carbon pools to climate change is essential for forecasting longer-term changes in soil carbon storage. Herein, we briefly synthesize information from recent studies that have been conducted using a wide variety of approaches. In our effort to understand research to-date, we derive a new conceptual model that explicitly identifies the processes controlling soil OM availability for decomposition and allows a more explicit description of the factors regulating OM decomposition under different circumstances. It explicitly defines resistance of soil OM to decomposition as being due either to its chemical conformation (quality) or its physico-chemical protection from decomposition. The former is embodied in the depolymerization process, the latter by adsorption/desorption and aggregate turnover. We hypothesize a strong role for variation in temperature sensitivity as a function of reaction rates for both. We conclude that important advances in understanding the temperature response of the processes that control substrate availability, depolymerization, microbial efficiency, and enzyme production will be needed to predict the fate of soil carbon stocks in a warmer world.

Many long hours of study and research have placed me at this point in my career, though I would be remiss if I failed to acknowledge those who helped guide and encourage my progress. First, I would like to acknowledge my Major Professor, Dr. Michael Essington, who has been both my friend and mentor. My gratitude must also be extended to my committee members, Dr. Mark Radosevich and Dr. Amy Johnson, for their support. Special thanks must go to Galina Melnichenko, without whose kindness and knowledge I would be lost. Thank you, Galina, for always being willing to help me work a problem through to a solution. I must also acknowledge my family and friends, whose love and encouragement has always been my shelter: my mother Virginia Jean Journey, who never lets me quit; my grandparents Thomas and Jean Journey; my grandmother Imma Lorene Bentley; my aunt Aurora Anne Daniels; and my best friends Amanda Odessa Beckner and Jennifer Lauren Webster, who have been like sisters to me. Finally, my thanks go out to all of those friends not mentioned who have never failed to show me love and support. I could never have come this far without you.
