• CSES 5033-- Plant Nutrition and Soil Fertility, Fall Even Years
  A discussion oriented course for graduate students and undergraduate students (with permission) on the importance of plant nutrition in crop physiology and metabolism and the importance of chemical, biological and physical processes in soil that influence nutrient availability.  Topics for discussion concerning plant nutrition include: nutrient uptake mechanisms and kinetics, active and passive uptake, water uptake, nutrient transport in xylem and phloem, carbon and nitrogen metabolism and regulation, source/sink relationships and macro- and micro-nutrient roles in enzymatic/metabolic processes.  Topics of discussion concerning soil fertility will concentrate on how elemental forms, chemical mechanisms and biological and physical factors in the soil affect nutrient availability and nutrient management as well as research techniques used in soil fertility.
  
• CSES 2012--Introduction to Organic Crop Production, Spring, 2009.
  Students will be introduced to the principles of organic agriculture and ecology and the regulations defining organic production and certification. Additional topics include crop rotations for pest management and for increasing soil organic matter, feeding the soil and plant nutrition, soil health, and green manuring. We will also briefly discuss corporate agriculture and genetically modified organisms. The course is targeted for freshmen and sophomore students who may or may not have a strong background in agriculture. NO PREREQUISITES
