Precision Turfgrass Management


Instructors: Bill Kreuser, Ph.D. and Michael Carlson Ph.D.

Precision turfgrass management uses observations, data, and models to improve management efficiency in turfgrass systems. This course will cover turfgrass growth potential, various turf and pest models, manipulation of growth with nitrogen and PGR programs, clipping volume, crop sensors, mapping data and construction of prescription maps for precision applications with variable rate sprayer systems.
