The 2009 season was a challenging, but dynamic, one. The number of projects was down slightly because of the economy, including the elimination of all but one of the NTEP (National Turfgrass Evaluation Program) trials. However, this allowed for improvements and changes of many sections of the research area. There was approximately 70,000 ft2 of newly seeded areas for future research projects, which included many species and varieties. The species were tall fescue (30,000 ft2 ), creeping bentgrass (8,000 ft2 ), perennial ryegrass (11,000 ft2 ), fine-leaf fescue (8,000ft2 ), and Kentucky bluegrass (13,000 ft2 ).
