GCSAA is launching the Golf Course Environmental Profile's nutrient survey. It concludes on April 27, 2007. Superintendents may receive an email invitation to participate, a paper version in the mail, and / or a fax invitation to participate. Some superintendents may receive both emails and mail surveys to help ensure project success. Please encourage your chapter's superintendent members to complete the survey.

* This is the third survey of GCSAA’s Golf Course Environmental Profile project. 
* Superintendents should complete and submit the survey by April 27. 
* Superintendents can access the survey at http://survey.ngf.org/r27004/facilitysearch.asp. 
* Regardless of previous participation with the environmental surveys, both GCSAA member and non-member superintendents may participate. 
* As a thank you for participation and full-completion of the survey, participants will automatically be entered into a random drawing for a $250 gift card, one of which will be awarded for each of the seven agronomic regions. 
* GCSAA members who complete and return the survey will receive 0.25 service points. 

For more information on the project, please visit: http://www.eifg.org/programs/baselinesurvey.asp 
This project is funded by The Environmental Institute for Golf, thanks to a grant from the Toro Foundation. 
Please encourage your superintendent members to respond to their email invitations, because each one has an unique URL within their email invitation that associates their survey with their courses.

A paper version of the survey is available, upon request.

Leonard Gregory, President Turf Star, Inc., Len has been in the golf business for 20 years as a Toro Distributor and began his career as a financial analyst. Len loved the outdoors, so he left the office environment and started his own landscape company "Westscape". Six (6) years later, Len sold the landscape company, and started a two (2) year sailing adventure from Sweden to Turkey, filled with numerous stops along the way .Upon his return, the opportunity arose to buy in to a small Toro house serving the San Diego market. Time took its course and they have now grown to represent the entire state of California and Northern Nevada. 

His formal education started with his undergraduate studies at UC Berkeley and completed his graduate work at UCLA. 
Len and his wife Janet of 25 years, have two children, a son Tye and daughter Sari. Tye is attending UC Davis and Sari is a freshman in high school. 

Len's interest outside of golf are sailing and cycling. His favorite vacation was his two-year sailing which he hopes to duplicate one day . 

The favorite golf course Len would like to play; He loves golf (appreciates the beauty of the natural settings and work that goes on behind the scene to accomplish this) but has not had time to play in many years.  He would really like to visit Augusta National and experience the level of perfection during the Masters. 

If Len wasn't involved with golf here is what he would love to be doing! "I really do enjoy working as a Toro distributor and the partnership that exists but if I were not working, I would love to be sailing on a catamaran in the South Pacific or Caribbean."

The Air Resources Board (ARB) is considering a rule that would impact companies that own off-road diesel equipment and vehicles like forklifts, scrapers, graders, backhoes and skid steer loaders and operate it in California.  The rule is scheduled to be considered by the ARB in April 2007.  Staff plans to hold workshops to discuss the proposed rule and solicit input on it in February 2007.  A brief summary of the proposed rule follows. 

All fleets would be required to report their affected equipment to ARB.  Then, annually, as vehicles are repowered, replaced, or retrofit, the changes must be reported to ARB.

All fleets would be asked to meet fleet average emission rate targets for particulate matter (PM).  Large and medium fleets would also be asked to meet fleet average emission rate targets for oxides of nitrogen (NOx).  The targets decline over time, requiring fleets to reduce their emissions as time goes on.  In order to meet the fleet averages, fleets have the option to retrofit their vehicles with verified emission control devices, repower them with cleaner engines, or replace them with cleaner vehicles (new or used).

SUMMARY 
Computer simulations of soil water flow were constructed for a USGA, California, and push-up putting green using HYDRUS-2D. The simulations generated animations of soil water content over a seven-day period for full-size greens having natural surface contours and supporting a closely mown turfgrass stand. Also generated was drainage rate and actual turf grass evapotranspiration (ET a). Rainfall and evapotranspiration scenarios were selected to challenge the hydrologic response of these three putting greens and a turf grass response protocol allowed the appraisal of water related turfgrass stress.
*  The simulations demonstrate the utility of deeper root- zone, as seen in the USGA and California greens, in providing a direct connection with subsurface drainage elements and displacing perched water below turfgrass rooting. 

*  Alternatively, the shallow root zone of the push-up green quickly became saturated during rain and remained nearly so for 42 hours, leading to aeration stress of the turf. 

*  During rain, the thickness of water perching was self-limited in the USGA green but continued to expand, forming a pattern relative to drainage spacing, in the California green. 

*  The simulations show that perched water can form in both USGA and California greens and, in both greens, may serve as a reservoir for subsequent water uptake by the turf. This perched water was, however, locally short-lived in both greens as down slope lateral flow removed it from the crest of steeper slopes within each green. 

*  The first appearance of drought stress was associated with the local absence of water perching in both the USGA and California greens, and appeared earlier in the California green due to the lesser water holding capacity of the root- zone.  >>>>Full Article

* Adequate nitrogen fertility to sustain moderate growth of annual bluegrass throughout the growing season (0.1 lb-N 1000 ft-sq. every 7 days) has been the single most effective cultural practice that can reduce anthracnose disease.

* Bimonthly applications of the chemical growth regulator trinexapac-ethyl (Primo) at rates ranging from 0.10 to 0.20 fl.oz.1000 ft-sq. throughout the season have reduced anthracnose severity. 

* The growth regulators mefluidide (Embark) and ethephon (Proxy) had an inconsistent effect on anthracnose over the past four years. However, turf treated with Embark or Proxy in the spring, with subsequent Primo applications throughout the summer, generally had less anthracnose and superior turf quality. 

* Turf managers can use daily-double cutting and/or lightweight rolling every other day to attain acceptable Stimpmeter readings without the need to lower the height of cut. A lower height of cut intensifies damage from anthracnose, while double cutting and rolling do not encourage the disease. 

* Four new field studies were established in 2006 and will continue through 2007 to evaluate the impact of sand topdressing, irrigation, and lightweight rolling on anthracnose disease.

2006 USGA Turfgrass and Environmental Research Summary

Used to achieve greater short-throw coverage for tee-boxes and other small turf areas on golf courses, Rain Bird® Golf's EAGLETM 351B Rotor Series is designed to provide superior water distribution and promote irrigation efficiency. To see the 351B Rotor Series in action, visit www.rainbird.com/eagle351b.

The EAGLE 351B is powered with rugged gear-drives and a unique nozzle design that ensures controlled and uniform precipitation on turf.  It has an 18- to 55-foot (5,5 - 16,8 m) radius of throw and operates at a pressure level from 60 to 90 psi (4,1 to 6,2 bars).  Because it provides full-circle and part-circle operation in one unit, the EAGLE 351B also reduces inventory requirements.  In addition, the EAGLE 351B has adjustable left and right side trips for ease of installation without turning the case.

"Superintendents no longer have to use commercial landscaping rotors in golf course applications," said Marc Negus, Rain Bird Golf's rotor product manager.  "Not only does the EAGLE 351B have solid design and construction for a high degree of durability and reliability, it also is interchangeable from the front without the need for any special tools."

Another key feature of the EAGLE 351B is Memory Arc®, which returns the rotor to its original arc setting.  It also has a unique nozzle design that provides superior water distribution and less sensitivity to pressure and spacing difference, with 1.3 or less scheduling coefficient at head-to-head spacing.  Furthermore, the nozzle has a pop-up height of 3.25 inches (8,3 cm) to clear taller grass.

Other key EAGLE 351B Rotor Series features include: 

Available in block (with SEAL-A-MATICTM device) models. 
Fully top-serviceable. 
Threads available in NPT, BSP and ACME. 
Water lubricated gear-drive. 
Self-adjusting turbine stator allows nozzle replacement with no other adjustment requirements.

The Rain Bird® Wind Tolerant Rotors were created to reduce the loss of range in windy conditions without significantly decreasing the distance of throw.  The Wind Tolerant Rotors accomplishes this through four key features:
