Courses Taught

HORT1103: Plant in the Home Environment

HORT3403: Turfgrass Management

HORT4913: Rootzone Management for Golf and Sports Turf

HORT4932: Turf Best Management Practices

Research Emphasis:

Initiated a turfgrass research program to improve the functional and aesthetic quality of turfgrass through the refinement of cultural practices, especially those pertaining to soil management.

  • Reducing the irrigation requirements of putting green and home lawn turf.
  • Wetting agent effects on surface characteristics of putting green turf.
  • Alternative establishment methods for sand-capped sites.
  • Effects of ethylene inhibition on the summer stress tolerance of creeping bentgrass.
  • Mowing height and frequency and rolling frequency effects on putting green speed and turf quality.
  • Screening turfgrass species, cultivars, and management practices for gains in drought tolerance.
  • Wetting agent effects on soil moisture distribution throughout sand-based turf rootzones.
  • Optimal management practices for sports turf overseeded with meadow fescue or tetraploid perennial ryegrass.
  • Putting green cultivation practices to minimize organic matter accumulation near the surface creeping bentgrass putting green rootzones.
  • Digital image analysis to quantify turfgrass characteristics.
  • Digital image analysis to quantify nitrogen and water status of turf.
  • Fertilizer and PGR timing effects on creeping bentgrass recovery from cultivation on putting greens.
  • Using cultivar / species selection and fertilizer programming to decrease collar encroachment into putting greens.
  • Assessment of localized dry spot severity in Arkansas.
  • Organic matter dynamics affected by cultivation practices on a sand-based putting green.
  • Effect of soil moisture controlled irrigation on summer stress decline of creeping bentgrass.
