Golf Courses

The turfgrass programs at WSU and OSU conduct research studies on turf management issues which directly affect industry professionals in the Northwest. Some of the projects include nitrogen fate, earthworm casting management, turfgrass water requirements, turfgrass variety evaluation, growth regulation, nutritional balance, and weed, disease, and insect control. As information becomes available from the studies it will be provided below.


  • Limiting Detrimental Earthworm Populations
    An update of a series of research projects which were initiated in the fall of 1997 designed for the “Development of an Integrated Management System for Reducing earthworm Casting on Golf Course Fairways.”
  • Effects of Mowing Heights and Fertility on Anthracnose Basal Rot
    A research update of the project which is funded by the GCSAA, WWGCSA, and OGCSA. Included is an introduction to ABR, purpose of the project, and methods to be used.
  • Nitrate Monitoring on Golf Greens
    A “Characterization of Leaching at the Coeur d’Alene G.C. Floating Green” which was presented by Dr. Bill Johnston at the WSU Puyallup Field Day.
  • Turfgrass Soil Management
    Abstracts of recently initiated research by Dr. Eric Miltner on calcareous sands, seasonal nitrogen dynamics, and cultivation and soil organic nitrogen.
