Reading questions will be assigned from the 4R manual and other sources most weeks
Course Description:
This course will begin with a brief review of quantitative problem solving strategies and then
quickly transition to exploring 4 topics:
1) 4R management (right source, rate, placement & timing)
2) manure and biosolids management
3) cover crops and other biological strategies to optimize nutrient cycling
4) IL & IA Nutrient Loss Reduction Strategies
Interview projects will play a key role in exploring these 4 topics from the perspectives of
diverse stakeholders (e.g., farmers, soil testing professionals, fertilizer industry professionals,
independent consultants, research scientists, regulators, policy makers and environmental
activists).
Course Objectives:
At the end of the course, students should be able to:
 Apply scientific principles and quantitative skills to nutrient management decisions
 Identify nutrient management stakeholders and describe how they participate
in current nutrient management issues
 Describe the role(s) that they would personally like to play in the future of nutrient
management

A set of reading questions/quantitative problems will be assigned most Mondays. Answers will
generally be due each Friday and must be submitted electronically using Western On-line. The
steps used to solve quantitative problems must be shown for each type of problem. There will be
~ 5 quizzes and 2 exams (mid-term and final). Students will each interview 3 different types of
nutrient management stakeholders and share 1 oral presentation based on interviews with the
class. Students will submit transcripts and short commentaries for *each* interview.
Attendance and deadlines:
Your attendance grade will be 100% if you miss 4 or fewer classes. You will lose 10% of your
attendance grade for each additional class missed. You will have 1 week to submit late
assignments for partial credit unless granted special permission.
