    Welcome to GreenKeeper University! This module is intended to introduce you to the Moodle Platform and give you resources to help you be successful.

    This course is co-taught by Dr. Jim Kerns and Dr. Paul Koch and provides a comprehensive introduction to the primary diseases of both warm and cool-season turfgrass. Students will learn how to identify diseases in the field, receive the most up-to-date research related to integrated disease control strategies, and work to develop comprehensive disease control programs specific to their location.

    This course, taught by Dr. Doug Soldat, covers the fundamentals of turfgrass soils and turfgrass nutrient management. After learning about the important physical and chemical properties of turfgrass root zones, students will be exposed to the most up to date information on soil testing and plant analysis, and gain experience with turfgrass nutrient management planning and using the NRCS Web Soil Survey.

    This course, taught by Dr. Bill Kreuser, covers weather basics, sources of weather data including forecast models, and technologies to measure meteorological data at your facility. Different weather events – such as excessive heat, cold, and drought – will be discussed in context to turfgrass physiology and management. Finally, the course will connect weather with turfgrass growth and development through models. Specific model examples include estimates of evapotranspiration (ET), seedhead and PGR GDD application timing, disease outbreak risk, and growth potential models.

    Managing pests are a critical skill of any successful golf course superintendent, and doing so in an environmentally responsible way is increasingly becoming required of all turfgrass managers. Dr. Paul Koch and Dr. Jim Kerns will provide the students in this class an overview of the basic principles of Integrated Pest Management, how those principles can be applied to golf courses of all expectations and budgets, and provide strategies for using pesticides in a manner consistent with sustainable turfgrass management goals.
