 Our research mission is to reduce energy input and associated
cost in the maintenance of turfgrass systems including golf, sports
and lawn turf. My research program focuses on understanding mechanisms
of turfgrass tolerance to environmental stress, with emphasis on
low temperature, drought, water use, and traffic (wear stress)
at the whole plant level. Our research is concentrated in two areas
including (i) evaluation of turfgrass germplasm to identify superior
stress tolerant grasses and (ii) the development of cultural practices
including irrigation and fertilization that can be used to alter
and improve stress tolerance. We are studying deficit irrigation
practices and nitrogen and potassium effects and their interaction
on low temperature hardiness, evapotranspiration, and wear tolerance.
We are also developing statistical models that may be more accurate
in predicting and identifying superior genotypes. We have demonstrated
using simulation and field studies that our models can result in
significant gains in turfgrass performance over standard (model)
recommendations. These models may replace standard statistical models
and allow for more reliable (accurate) turfgrass selection and recommendations.
Accurate turfgrass selection is the foundation of an effective Integrated
Pest Management program to reduce the use of water, fertilizer and
pesticides.
