"unique" means "one of a kind" or "having no like or equal."This magazine is unique.
No other publication directly supports the Sports TurfManagers Association. When you buy a product or service
from a company that advertises in this magazine, you are indirectly help-ing to strengthen the STMA. Through the contract M2MEDIA360, thismagazine's parent company. has with STMA, a certain percentage of ouradvertising revenues flow to the association's coffers. There is no othermagazine that has this relationship with STMA.
In turn, the association has increasingly in the past 2 years undertak-en projects that are raising the sports turf profession's profile and pres-tige around the country. While this increased attention can be stressful attimes, e.g., your under-6 soccer parents are asking why the kids' fieldisn't as green as the ones on TV, it also is leading to more awareness ofwhat you do and its importance as part of the games. And that (hopeful-ly!) will lead to higher salaries for sports turf professionals.
Everyone involved in producing this magazine, including the STMAmembers that serve on our Editorial Subcommittee. are dedicated to pro-viding you an interesting. easy-to-read magazine each month. If there's atopic you would like to see us address, please let another subcommitteemember or me know. The staff of SportsTurf is proud to be the officialpublication of the STMA. This is your magazine as much as it is ours, andthe better our magazine is, the better the sports turf profession will be.
I would like to call special attention to the content on pages 40 and41 in this issue, "Lawn sweepers find a new home on sports turf" in our"Tools & Equipment' section. These pages are sponsored by a company,Parker Minuteman, which has manufactured a "lawn sweeper" productfor nearly 100 years. The company, working with our sales staff andLands Conference, an online continuing education firm specializing in the'green" industry. has produced what we are calling a "webmar." Thiswebinar program enables you to see and hear an online product demon-stration of this Parker Minuteman lawn sweeper, in action at a profes-sional stadium.
We think this will be the first in a series of webinars featuring all kindsof products. Please check it out and let me know what you think. If thesewebinars catch on the way we think they will, they will be just one moreway we are helping our sports turf manager readers do a better job. andassisting the STMA in reaching their goals as well.

collision between a player and the playing surface
is inevitable in almost every sport. If the field's£. ability to absorb shock energy is low, then the play-er's body has to absorb more. That's why we test
... fields for surface hardness.Hardness measurements help you to identify any foreseeable risk
that might affect your players, and lets you determine if you need totake action to reduce those risks. Actions for synthetic turf surfaces arestill being defined, but synthetic turf managers are using management

practices ranging from the brushing and grooming of these surfacesto the partial or complete replacement of these fields,
Natural field hardness is reduced through maintaining a healthyturf stand and thatch layer, adequate soil moisture, and aggressivecore cultivation programs. Eventually either type of playing surface willneed to be replaced.
Testing also allows you to track changes in hardness over time and,for synthetic turf systems, to insure that the field is functioning aspromised in the manufacturer's warranty. Manufacturers are providing

limited warranties on field hardness for as long as 8 years. It isimportant to test a field shortly after completion, preferably within 30days, to get baseline hardness values, then perform annual or bi-annual testing to monitor changes.
Annual field hardness testing and documentation is also crucial inthe event of a player injury. All parties involved in the constructionand maintenance of the field could be held liable for the injury. Beingable to provide written documentation of your hardness monitoringand maintenance programs will show your efforts in reducing anyforeseeable risk to the players. This is especially important now thatstandard procedures have been adopted for monitoring the hardnessof synthetic and natural turf playing fields. A maximum hardnessthreshold value has been adopted for synthetic fields.
What affects hardness?The hardness of the playing surtace is dependent, on many things. Insynthetic turf systems it is dependent upon the type of carpet andinfill, the presence or absence of a shock pad below the carpet, andthe type of base the carpet is laid on. Carpet fiber height and densi-ty affect shock absorbency to a certain extent, but the amount andtype of infill material is more critical.
Infill materials are composed of either crumb rubber or a crumbrubber: sand combination and shock absorbency goes up as theamount of crumb rubber in the infill mix goes up. Placing a rubbershock pad between the carpet backing and the base material cangreatly increase the shock absorbency of the system. These rubberpads come in various thicknesses with a to-mm thickness beingcommon. A good shock pad can even allow for more sand in the infillmix. without a reduction in shock absorbency. This sand can make fora firmer and faster playing surface, which many athletes prefer.
