Greening Up the Greens - Transpiration Application Scenario
Date of this Version
Plant and Soil Sciences eLibrary (PASSeL) Lesson
A scenario to accompany the online lesson “Transpiration - Water Movement through Plants.”
You are a student intern for the summer at Fall Oaks Golf Course in eastern Nebraska. After working there for a month, you notice that the greens are not in the greatest condition. In the morning the greens are a lush green color, but then during the middle of the day areas turn bluish-green to brown. The greens seem to recover their green color later in the day, but the plant density (thickness of the greens) has been steadily decreasing since you started working there in early June. The other intern, who worked there last summer, comments that it sure didn’t look like this last year!
[Photo: Greens under heat stress turn bluish-green to brown in color and plant health decreases.]
You decide to impress your boss by taking the initiative to determine how to correct the problem. Before you can make a recommendation, though, you need to gather some information to figure out what the problem is and how it can be remedied. Your first step is to find out more about the management practices for the greens. You can ask your boss, a Certified Golf Course Superintendent, any of the following questions.
Q: How much is the golf course used?
A: There is a significant level of rounds played (> 45,000 per year), with most summer rounds being played in the morning or late afternoon.
