Jackie's thesis at Michigan State University was titled "Effects of Different Soil Testing Philosophies on Creeping Bentgrass and Annual Bluegrass Putting Greens." She looked at how much P and K were applied by different interpretation philosophies, how the grass stood up to traffic, and what happened to the elements that were applied.
