"Doc", ashe was admiringly referred to, alsoserved as the association's firstHistorian, and amassed an amaz-ing collection of document andphotographs of the sports turfprofession and STMA. Doc's col-lection included a kind donationfrom the estate of turf industrypioneer Dr. Fred Grau. In appre-ciation of Doc's contribution and

the generous donation of the Kurtzfamily to STMA we will be runninga monthly account of the people,places, stories, equipment; and pho-tographs that arc important to theprofession and association.

Hold on to your photos!Starting this spring, and in order toenrich Doc Kurtz's collection, theSTMA Historical Committee willbe running a contest each month tosee who has the most unique pic-tures of sports turf specific equip-ment and significant STIVIA mem-bers. Look for details in this sec-tion in future issues! •

This photo from the STMA Kurtz Historical Collection taken at Metropolitan Stadium in Minneapolis. shows STMA Founder Dick Ericson's crew using Wooley WeedBurners to thaw out the warning track. Often sports turf managers were forced to come up with innovative ways to prepare the field for athletic competition.Originally designed for use in parking lots for weed removal, Wooley Weed Burners were used by early sports turf managers to dry wet infields for play and burnoff weeds in preparing a seed bed.

Less water -- tougher renovationc want to renovate the bermudagrass onour high school football field this spring.VI/e have some heavily worn areas downthe center and the !;iddine!; but the restof rhe field is ok. I think the Held was

originally sprigged to Tifway about 10 years ago, but that wasbefore Iwas hired. We have decided to use a new seededcultivar but we are not sure if we should take out the entireHeld or just seed into the worn area. One of our biggest issuesis that we can only water the fields 1day per week due to ourlocal water restrictions. Any advice you can provide would beappreciated.

North Carolina

It seems 90% of the questions I have received the last fewmonths have a drought component. My answer to your ques-tions will be tempered based on your inability to irrigate. Ifirrigation was not an issue, your options would be a little dif-ferent and the assurance of success would be much greater.

I will provide an overview of establishing via seeding, butyou may want to download ''A Guide to Establishing SeededBermudagrass in the Transition Zone" that was recently pub-lished. It was written by experts from Alabama, Arkansas,Indiana, Kansas, and Mississippi based on their years of com-bined experiences. It can be found at the Applied TurfgrassScience website, address: http://wv,w.plammanagcmcntnct-work.org/ats/, under the headline Turf Management Guides.

This guide provides pages of useful information related tocultivar selection, seeding date, site preparation, seeding rate,weed control, fertilization, and costs. It does not provide rel-evant information related to irrigation management or sug-gestions for establishment without irrigation. The unfortu-nate reality is that most published recommendations aredesigned to minimize seedling stress and competition forlight, water, and nutrients. Establishing a field without irriga-tion carries additional risks far beyond establishing an irri-gated field.

If you have not yet selected your seeded cultivar, you couldread through the information in table 1 of the guide, or lookat the National 'Iurfgrass Evaluation Program data (nhttp://www.ntep.org) for your region to help you decide whichmight be best. As is noted in the guide there is a wide rangeof cost for bermudagrass seed (about 55 to $25 per pound).Often the more expensive cultivars are those that produce thefewest seed heads, which is used by some people as a measureof quality. You should also check with your local seed sup-plier to see what is currently available.

But before you purchase the seed, you will need to decideif you are going to renovate the entire field or just the wornareas. If irrigation was not such an issue, I would suggest yourenovate the entire field. You have time on your side and the

field would look and play much more consistent. With regu-lar rainfall and once per week irrigation, there is still a chancethat yOll could successfully renovate the entire field, but thereis the risk of slow germination and poor growth followingestablishment if the turf docs not get adequate moisture.

Since you already have at least half your field grassed withan improved cultivar and your extensive midfield wear indi-cates you are getting more traffic than the field can normallyhandle, Iwould recommend just seeding the bare areas thisyear. Most of the newer seeded bermudagrass cultivars willblend reasonably well with Tifway. Once you get the linespainted for football any difference in texture or color will beeven less noticeable. Given your situation Ibelieve having turfcoverage is more important than visual consistency.

Research has shown that early seeding dates are not det-rimcntal in terms of seedling winterkill and may actually havesome advantages. Bermudagrass generally does not germinateuntil temperarures reach 68 degrees but seed can be plantedwhen the temperanlres arc cooler (mid-February to midMarch rather than April to June) and will remain in the soiluntil conditions are conducive to germination.

Before planting thoroughly core acrify the area to beseeded to alleviate compaction and open the soil. Then lise arotary spreader or slit seeder to apply [he seed evenly and atthe appropriate rate. A slit seeder would be the ideal ''Vay toplant, but if one is not available then carefully rake broadcastseed into the top 1/8 inch of soil using a leaf rake or nail drag,and then tightly roll to improve seed-to-soil contact.

Once planted the recommendations are more difficult tomake because you only have one fixed-day per week to water.You are now depending on Mother Nature and you hope thatshe graciously provides you with rainfall.

You want to irrigate as efficiently as possible so make surethat your irrigation system is working and provides goodcoverage. This is best accomplished by putting out at least acouple of catch containers between each head to check catchamounts and by looking for dry spots during and after anirrigation cycle. Make adjustments or replace heads if thereare distribution problems.

Once the seedlings start to emerge, apply about 0.5pounds N/l,OOO sq. ft. using a soluble source of N (e.g. urea)just before an irrigation cycle. Continue to apply about 0.5pounds every 2 weeks as long as there is adequate soil mois-ture until the turf is well established. Apply other nutrientsbased on a soil test. I would avoid the use of herbicides ondrought stressed turf

There is no guarantee that this is going to work. Withoutwater turfgrasses will not germinate and without adequatewater it will not remain healthy. But I believe taking thiscourse of action is better than doing nothing .•
