Soil reaction/cycling of elements essential to plant growth; rates, timing and placement of nutrient sources in modern crop/soil management systems; plant and soil sampling and analysis to diagnose plant nutrition stress.

This course will enable students to critically assess, analyze and evaluate forage production and utilization practices on livestock-forage operations in Kentucky and the mid-south region. The course will emphasize the integration of forage science and practice.

Overview of the grass family, concentrating on taxonomic issues and identification skills for 200 species (turf, forages, weeds, etc.). Lecture: two hours; laboratory: two hours per week.

This course is an introduction to the science of environmental pollution with an emphasis on fate and transport of contaminants and adverse effects on biological systems. Pollutants covered include metals, pesticides, organics, radionuclides, nanomaterials, and nutrients. The course covers physiological and toxicological effects of chemicals on natural biota, including considerations at cellular, organismal, population, community, and ecosystem levels.

Soil microbiology is the study of the macro- and microscopic life in soil: what it is, how it adapts to the soil environment, what it does, and why it is important. This course emphasizes interactions between organisms and their environment and how these interactions affect the world in which we live. Critical thinking skills will be emphasized, particularly the ability to interpret data collected during microbiological investigations of soil.

Each semester five distinguished scientists visit the UK campus to deliver a series of three formal lectures each and participate in numerous informal contacts with graduate students. The emphasis is on the presentation of the most current advances (often unpublished) in selected topics in molecular and cellular genetics. May be repeated to a maximum of six credits.
