GEOG 215 The Biosphere

An introduction to the planetary biosphere, its living organisms, and their interactions with each other and the Earth system.

GEOG 317  Soil Science

This course provides an introduction to the study of soils. Topics covered include the physical, chemical and biological properties of soils; soil formation, description classification, survey and use. Students have the opportunity to learn field and laboratory techniques of soil analysis.

GEOG 318  Soils in our Environment

This course provides a survey of soils and their management. The course focuses on the role of soils in the environment; their physical, chemical and biological properties; process of degradation (including erosion, desertification, pollution, and nutrient depletion); and the maintenance of healthy soils. Students have the opportunity to study soils both in the field and in the lab.

GEOG 417  Advanced Soil Science

This course provides advanced treatment of topics in soil science: soil physics, soil chemistry, soil biology, soil classification and/or forest soils. Currently the course focuses on the properties and management of forest soils including such topics as: the forest floor, litterfall, roots, mycorrhizae, nutrient availability, climate change and soils, and forest management practice impacts on soils.  Students have the opportunity to study soils in the field and in the lab.
