Greenhouse Gas Analysis Lab

This lab provides analytical support for the measurement of greenhouse gases (CO2, CH4, N2O) in stored samples. This provides a cost-effective means of measuring greenhouse gas emissions from a wide range of ecosystems.

Research

Dr. Burton’s research examines the role of the soil environment in influencing the nature and extent of microbial metabolism in soil. His current research programs involve an examination of the production and consumption of greenhouse gases in natural and agricultural landscapes, sustainable manure management practices, bioremediation of hydrocarbon contaminated soil and the assessment of the quality of the soil biological environment and its influence on overall soil quality. It is the aim of this work to better understand the factors that control microbial metabolism and to use this information to developing sustainable land management systems.

Teaching

  • SOIL 3000 – Soil Fertility and Nutrient Management – This course provides detailed information on plant nutrition, soil fertility, and fertilizer management of the essential plant macro  and micronutrients. The influence of numerous soil biological, physical, and chemical properties on plant nutrient availability to crops will be emphasized. Students will be familiar with the management of nutrients to optimize productivity and minimize environmental impact.
  • ENVS 4006 – Air, Climate and Climate Change - This course examines the composition of our atmosphere and how it functions to create weather and climate.  A fundamental understanding of chemistry and physics of atmospheric processes will provide the basis for an examination of micro, regional and global scale meteorological processes.  The expression of these meteorological processes will be examined over time and space as a means of examining climate and climate change.  The global debate surrounding anthropogenic greenhouse gas emissions and climate change will be considered from scientific, social and political perspectives.  The laboratory portion of the class will examine the tools for measuring the composition of the atmosphere, the physical state of the atmosphere and the transfers of heat and mass to and within the atmosphere.
  • MICR 4000/AGRI 5125 – Soil Microbiology - This course focuses on the life that inhabits the soil and the various functions mediated by these organisms.  It is not an exhaustive taxonomy of organisms but rather a survey of the major types of organisms and an examination of their role in soil function.  The role of soil biology in ecosystem function will be examined and how management influences soil biological function.  Challenges to, and emerging opportunities in, the measurement of soil biological processes will also be considered.
  • RESM 4006 – Environmental Sciences Project Semiar I - the first of the Project-Seminar courses required of all students enrolled in the Environmental Sciences major. RESM4006 is designed to develop a proposal and literature review for a research or design project. The results of which will be the basis of their final report due during the second Project-Seminar course (RESM4007). The course emphasizes communication skills - written, verbal, and electronic. Students prepare a written research proposal and a literature review. Each student also presents a seminar on their project and are required to participate in all class discussions.
