On the Fairway, New Lessons in Saving Water

Monday, October 26th, 2009

When a few drops here and there are enough, workers use watering cans to moisten the greens at the Atlanta Country Club.

ATLANTA — Six years ago, when Georgia’s state government rewrote its rules for water use during droughts, it cut no slack for an obvious culprit: golf courses.

With emerald fairways that glistened even in the most blistering conditions, they were a tempting target.

Yet golf course managers were indignant. They argued that they were reining in water use in dozens of ways, like planting native grasses and auditing sprinkler spray patterns. Instead of being penalized, they said, they should be emulated.

It took a while, but from the South to the arid West, their wish is coming true. Mindful that global warming could provoke more and longer dry spells, state governments are increasingly consulting golf courses on water strategies.

In Georgia, golf course managers have emerged as go-to gurus on water conservation for both industries and nonprofit groups.

Marriott International is applying lessons learned at its golf course here to its resort properties in other states. Habitat for Humanity is landscaping front yards with drought-tolerant plants recommended by golf superintendents.

“Look, if you want to learn how to irrigate, these are the guys to ask,” said Garith Grinnell, who recently retired from the Southern Nevada Water Authority.

Such accolades are a turnabout for a business that is often faulted for harming the environment through excess use of water and pesticides.

In Georgia, the shift in perspective came about largely because of a crippling drought that peaked in 2007. By that year, 97 percent of the clubs that belonged to the Georgia Golf Course Superintendents Association had voluntarily adopted what are viewed as best-management practices for water use, reducing consumption, they estimated, by 25 percent in just three years.

Lake Lanier, Atlanta’s main source of water, had meanwhile dropped to record low levels, exposing muddy bottom not seen in half a century. It dawned on state and local water managers that golf courses might have some useful know-how.

Golfing grounds managers “are great technical assistance to me,” said Kathy Nguyen, president of the Georgia Water Wise Council, a state association of water professionals that encourages conservation. “I can call them up and talk to them about different technologies.” (Georgia’s drought eased significantly this year.)

Ms. Nguyen has relied on golf superintendents in drafting guidelines for homeowners like letting grass grow longer, fixing leaks in hoses as promptly as possible and keeping lawn mower blades razor sharp. (Grass cut by duller blades is more frayed and requires more water to stay healthy.)

The golf industry still draws strong criticism from environmentalists. Turf is, after all, the thirstiest of plants. The average American golf course drinks up some 50 million gallons of water a year — comparable to the yearly usage of 1,400 people. In the West, the figures are higher.

Yet that reality, coupled with rising water prices, is what led to strides like irrigating golf courses with “gray water,” or nonindustrial wastewater that is recycled for other purposes.

Tom Bancroft, chief scientist with the National Audubon Society, says that for all the progress golf has made, it remains a deeply problematic industry. Many courses “use fertilizers that can run off into fresh water, and many use pesticides in lawn and grass,” Mr. Bancroft said. (Audubon International, a separate group, works with golf courses to encourage wildlife preservation.)

Mark Esoda, superintendent of the Atlanta Country Club in suburban Marietta, where initiation fees are $85,000, acknowledges that practices among the nation’s courses range from indifferent to conscientious. But Mr. Esoda maintains that he and other superintendents have a lot to teach municipalities about watering their ball fields and homeowners about tending to their yards.

Zipping around the course on pine-shaded paths, Mr. Esoda stopped abruptly near the seventh hole. He gestured toward a patch of newly laid turf of zoysia, a warm-weather shade grass native to Southeast Asia and Australia. On shady parts of the course it is replacing fescue, a genus of cold-weather shade grass that can live through the winter and thus requires five months’ more watering and mowing.

Mr. Esoda said he had also installed affordable monitors that prevent automatic sprinklers from activating during or right after a rain.

And when isolated dry spots appear on the greens, he said, he sends staff members out with watering cans rather than turning on the sprinkler system.

Finally, Mr. Esoda has made an aesthetic adjustment after years of savoring the green glow of a perfect lawn. “Crispy around the edges is O.K.,” he confided.

Water is just one area where golf courses and environmentalists may find a rapprochement, said Anthony L. Williams, director of grounds at Marriott’s Stone Mountain public courses just outside Atlanta.

As metropolitan areas sprawl outward, golf courses may be the only large-scale green space for miles around, offering crucial potential habitat for migrating birds and other wildlife.

Mr. Williams, who has a degree in local horticulture, has been letting native grasses take over his lawns. Off the fairways he does not even bother to mow, and on the greens he is maintaining grass at one-sixteenth of an inch higher than typical courses. It makes playing slow, he allows, but “consistent.” He has also replaced all the flowering annuals with perennials, which generally require less water, choosing those that are attractive to native wildlife.

Since he took charge of the two courses in 2005, Mr. Williams has cut water consumption by 45 percent, he said, and witnessed the return of some wildlife species like the red-tailed hawk.

The changes have come with a price, like the occasional large brown spot on the fairway. But Mr. Williams says the golfers do not mind.

“I just stand out there on the greens and explain, ‘We are doing this so your grandchildren can come out here and play,’ ” he said. “People understand that.”

A Lawn as Healthy as It Looks

Thursday, October 22nd, 2009

IN honor of spring and the ongoing quest for the perfect lawn, the Green Home asked Bill Duesing, an educator with the Northeast Organic Farming Association, a nonprofit group devoted to sustainable farming and gardening, for tips on achieving an attractive yard without wreaking environmental havoc.

Americans bought 4.5 million tons of bagged fertilizer in 2007. Does that pose any problems for the environment?

Conventional fertilizers contain more nitrogen and phosphorus than your lawn usually needs, which disturb the soil’s ecosystem. They also wash away and end up in bodies of water, where they can kill plants and fish. A lot of conventional fertilizer also contains herbicide and insecticide, which have other chemicals that can potentially harm human health.

What’s a greener alternative to conventional fertilizer?

Use compost, which is organic and is the best food for your soil. Good soil has more than 6 billion living organisms in a small handful — bacteria and fungi that are able to take nutrients out of rock particles and organic matter to feed the grass.

What if you don’t have a compost bin?

Bagged compost is available, and there are bagged organic fertilizers that have things like feather meal, alfalfa meal, granite dust and animal manure. But rehabilitating a yard can be challenging because you have to wean the lawn from the chemicals and rebuild the life in the soil. In some cases, you may want to talk to a professional.

What other steps should we take?

There are three things everybody can do that are fairly inexpensive and very useful. One: add rye or fescue seed to your lawn. These are grasses that are lower maintenance than varieties like bluegrass. It’s like having a mutt from the pound as opposed to a pedigreed dog that needs a lot of grooming.

Two: sow clover into the lawn. It’s a legume, which takes nitrogen out of the air and puts it into the soil. If your lawn has even 5 percent clover, it can provide half of the lawn’s nitrogen. Basically it’s your lawn’s own solar-powered fertilizer factory. White Dutch clover is widely available and sturdy.

And three?

Leave the grass clippings on the lawn — they add nitrogen to the soil. And in the fall, instead of raking the leaves, chop them up with the mower and leave them there. It provides food for the soil’s organisms.

Speaking of mowers, it is estimated that we use more than 800 million gallons of gasoline to mow our lawns each year, contributing to our nation’s air pollution. Should we replace our gas-guzzling mowers?

If you insist on having an engine, use a mulching mower, which is designed to return grass clippings to the soil. A better alternative is a rechargeable electric mower, which produces less pollution and is quieter. But really, the best thing is to keep your lawn small enough so you can mow it with an old-fashioned reel, push mower. Let the rest be meadows, gardens or woods.

How often should we mow?

Wait until the grass blades are 3 to 3.5 inches. Not only does that discourage weeds, but it helps conserve water. Mowing the grass high tends to encourage the roots to go down deeper, where they get more nutrients and need less watering.

What about every gardener’s nemesis: weeds?

If you fill your lawn with low-maintenance grasses, some weeds get choked out. But other weeds are good: I like to eat dandelions, and clovers keep green all year long. If there are patches you consider too large, there are organic herbicides like BurnOut II Weed & Grass Killer. It kills all broad-leaved plants and is made of strong vinegar.

Many of your tips sound easier than typical lawn care. Why do you think we’re so obsessed with having lawns that resemble golf courses?

I think it’s advertising. We’re bombarded by commercials saying how much we need a perfect lawn.

Code to Require Home Sprinklers

Monday, October 12th, 2009

Building code officials who gathered in Minneapolis this week voted overwhelmingly to approve a change to a model code used by states and cities around the nation that would require the installation of sprinkler systems in new single-family homes and town houses.

Each city and state that uses the International Residential Code has the option of ignoring the mandate, but the adoption creates a national standard that is likely to mean that many more communities honor the requirement.

The change was challenged by home builders, who questioned whether homeowners would properly maintain the systems, but it was supported intensely by firefighter groups.

Sprinkler systems cost about $3,500 for the average new single-family home, according to industry estimates.

The requirement will go into effect for town houses in 2009 and single-family homes in January 2011 for jurisdictions that adopt the 2009 version of the code.
