Publications

My publications stem from projects related to my postdoctoral work and PhD and MSc theses. Research themes include:

-Carbon storage in buried soils and soil organic matter destabilization under erosion and climate change
-Soil organic-inorganic carbon transformations in giant termite mounds of South Africa
-Environmental factors contributing to oxalate salt composition of plants and termite frass in mesic to arid zones
-Evaluating infrared spectroscopic techniques of quantifying oxalate salt content of plant tissues and termite frass as well as soil pH and base cation content
-Comparing international methods of measuring cation exchange capacity of varied soils
