Olathe Horticulture Research-Extension Center


The Olathe Horticulture Research and Extension Center, in rural Johnson County, Kansas, is K-State's premier location for vegetable and turfgrass research. Situated on buffer ground on the eastern edge of what was once the Sunflower Army Ammunition Plant, the center has 342 acres that include 150 acres of native woodland, 75 acres of bottomland, and 117 acres of upland soil grassland. Vegetable and turfgrass research plots cover approximately 50 acres of bottomland. Spoon Creek runs through the site and provides irrigation water for research plots. The Center, which is part of Kansas State University's Eastern Kansas Research-Extension Centers, supports five full-time employees, several graduate students in the Urban Food System and Turf Management programs, and part-time summer student workers.

Our Vision:

To be a regional resource and center of excellence in applied research and extension programs that serves the current and future needs of turfgrass, landscape, fruit, vegetable, and forestry industries as well as the local and regional economies they support.
