Root Zone Management

Logo2017_Root Zone Management

This 2.5-hour class consists of pre-recorded lectures about the fundamental concepts about irrigation water, media, and their effects on plant nutrition. The course covers the latest practical information on root zone management techniques for ornamental crops in a greenhouse.

The course is instructed by Heidi Lindberg, Greenhouse and Nursery Extension Educator with MSU Extension. Dr. Kristin Getter (Academic Specialist, MSU) designed, authored, and updated the course, which was adapted and updated from the original College of Knowledge class developed by Dr. John Biernbaum (Professor, MSU) and later revised by Dr. Dean Krauskopf (retired Educator, MSU Extension).

Students enrolled in this self-paced course will take a pre-test and a final exam to gauge their progress on the topics of the course. Self-assessment quizzes will engage students with the material throughout the course.
