Research

Dr. Travis Shaddox develops best management practices for the lawn, golf, sport turf, and sod industries. Specifically, his research focuses on soil fertility and turfgrass nutrition with consideration given to reducing costs and environmental risk from the application of granular and foliar nutrients. In addition, Dr. Shaddox continues to develop reliable interpretations of soil and tissue tests for turfgrasses.

Extension

Dr. Shaddox is a state turfgrass extension specialist who addresses soil fertility and nutrition issues in the golf, lawn care, sport turf, and sod production industries. He travels extensively supporting county extension faculty. In his prior position in Florida, his extension program was the Florida and Southern regional winner of the Excellence in Consumer or Commercial Horticulture by the National Association of County Agriculture Agents.
