University of Maryland Turfgrass Technical Updates

In Fall 2002, the turf researchers of the U.M. Dept. of Natural Resource Sciences & Landscape Architecture began a complete revision of the series of Agronomy Mimeos they had developed over the previous 20 years. The new Turfgrass Technical Update series includes a new masthead, color photos, and a tighter layout in Adobe Acrobat (.pdf) format that makes them easier to download, read, and print from the internet.

Although the TT Updates use different numbers for most publications adapted from the discontinued Agronomy Mimeo series, some publications such as TT-77 ‘Recommended Turfgrass Cultivars for Certified Sod and Professional Seed Mixtures’, retain the old number and title to emphasize that TT-77 replaces AM-77.

The Maryland Turfgrass Council (MTC) is currently the internet host, and new TT Updates are announced in ‘MTC News’, a quarterly newsletter that is mailed to MTC members and free online at . Revised TT Updates are released as they become available. TT-02 shows the titles, authors, and most current release dates of the Turfgrass Technical Update series.
