Natural Resources Courses

Listed below are brief descriptions of the natural resources courses offered by the William H. Darr College of Agriculture. Please note that graduate courses are numbered 600 and above.

Agricultural Natural Resources (AGN) courses

  • AGN 115 Sustainable Agriculture and the Environment

    This course examines the practice of agro-ecology: the interface of management, biology, and the environment in our effort to produce food, feed, and fiber for a rapidly growing human population. Consequences of historical and current practices, as well as strengths and weaknesses of alternative practices that attempt to employ more knowledge of biology and ecology, will also be evaluated.
