sunny-side up with a pinch of lead

On October 8th the New York Times published an article by columnist Julie Scelfo, revealing detectable levels of lead in the eggs of city-raised chickens. The article discussed a recent New York City Health Department study, in which researchers found lead in amounts of 10 to 100 parts per billion in roughly half the eggs tested. The other half of the sample was free of lead, as is typically the case with a grocery-bought dozen. The sample eggs were laid by chickens occupying neighborhood gardens in Brooklyn, Queens, and the Bronx, which presumably browse on ground-level plants and insects. The article ignited conversation about free-range fowl among urban agriculturalists.
Lead consumption is a serious concern, particularly for young eaters, whose small bodies are more sensitive to contaminants. While Scelfo notes that the Food and Drug Administration has not designated acceptable levels of lead contamination in foods, chicken owners and urban farm supporters alike are undeniably nervous about lead consumption at any level.
How do we prevent lead contamination in urban eggs? Bring your feathered friends to the roof. Grazing rooftop chickens will pick through the soil that you provide, rather than the who knows what down below. By bringing in and building your own soil, you have control over what enters their beaks, and your breakfast. What’s more, is that the chickens will pluck pesky pests from the soil, while fertilizing your rooftop crops! It’s a win-win situation.
Notable rooftop farms like Brooklyn Grange and Eagle Street Rooftop Farm boast resident chickens. These lead-free birds help the farmers, while laying healthy eggs in their rooftop coops. As with many ground-level farms, chickens play an important role in agrarian rooftop ecosystems.
I’ll take my eggs with a sprinkle of salt and a side of potatoes; no lead for me please.
get ready, windy city!
Chicago‘s rooftop community will beam from October 17th to 20th, as the City of Chicago and Green Roofs for Healthy Cities host this year’s international green roof conference. Cities Alive is poised to attract design, policy, green roof, and agricultural professionals from around the globe, in celebration of the conference’s 10th anniversary.

With a hunger for rooftop agricultural knowledge, several food-related technical sessions and site visits are on the docket. If you’re able to attend, be sure to stop by Session 2 on the 18th: Emerging Design and Technology Trends in Rooftop Urban Agriculture. This hot button panel will feature Helen Cameron, co-founder of Uncommon Ground (America’s first certified organic rooftop farm and winner of numerous restaurant and sustainability awards); Bradley Roback, Coordinator of Economic Development for Chicago’s Department of Housing and Economic Development (Brad focuses on food policy and land use planning); Mark K. Morrison, President + CEO of MKM Landscape Architecture PC (a New York-based landscape firm with a history of green roof design); and Lauren Mandel (yours truly). Sky Vegetables, Inc. founder Keth Agoada will moderate the session, and the conversation is sure to stimulate your imagination.
Rooftop agriculture is gaining steam at conferences like Cities Alive, and August’s Urban Agriculture Summit in Toronto. Sessions on the topic are routinely packed with curious, energized attendees. Will this trend continue as entrepreneurs, the media, and academia continue to explore the potential of rooftop food production? You betchya.
Check out the rest of the 2012 Cities Alive program, and stop by our panel to ask the experts your toughest questions!
goat à la roof
While some skyline growers tinker with beets and collard greens, others push the limits of hoofed farm hands. Rooftop goats are all the rage in Sister Bay, WI, where a small herd has grazed the grassy roof of Al Johnson’s Swedish Restaurant & Butik since 1973.

Restaurant founder Al Johnson explained in a 2007 interview that sod roofs are common in Sweden, where he was born, as a means of moderating a building’s indoor temperature. Johnson decided to install a sod roof atop his Wisconsin restaurant, and rather than mowing, he introduced a herd of goats to keep the lawn at bay. As it turns out, the goats draw large crowds to the now iconic restaurant, particularly during the summer months. In addition to providing utilitarian services like mowing, rooftop goats are fully capable of supplying milk, meat, and even wool. Their milk can be used for drinking, making dairy products (like cheese and yogurt), and also for crafting soap and other value-added products. These rooftop ruminates sure do give you a lot of bang for your buck… er, ah, for your billy? A little goat humor.
Check out Al Johnson’s goats for yourself, through this live feed to the restaurant’s Goat Cam.
collective brain power
From August 15-18, urban agricultural enthusiasts from around the world gathered in Toronto for the very first Urban Agriculture Summit. The international conference, hosted by Green Roofs for Healthy Cities and FoodShare, attracted over 500 farmers, activists, educators, CEOs, design professionals, developers, and other industry leaders to discuss current initiatives and explore the future of urban agriculture.
Seated tightly in a lecture hall at Toronto’s Reyerson University, we listened to the conference’s opening remarks while fidgeting in anticipation of the lectures, panel discussions, and brain mingling to come. Topics would range from social issues (food security and community building), to the sciences (urban ecology and technology), to implementation (planning, design, financing, and policy). An astounding assortment of industry leaders were in attendance – all the hot shots were there. Will Allen, Founder and CEO of the Milwaukee-based agricultural organization Growing Power, kick-started the conference with an inspiring keynote address. Brightfarms CEO Paul Lightfoot maintained the conference’s momentum with an eye-opening talk about his greenhouse hydroponic company’s innovative business model. High-profile rooftop farmers, like Ben Flanner from Brooklyn Grange, led workshops and sat on informative panels. Architects and landscape architects offered insight on the practicalities of designing urban agricultural spaces, and community gardeners discussed best practices for maintaining them.
The conference’s emphasis on rooftop agriculture attracted quite a crowd. I presented on rooftop production techniques to a room of 60 or so attendees, and the rooftop buzz hummed throughout the rest of the conference. One of the most fascinating panel discussions I attended paired rooftop row farmer Ben Flanner with Kurt D. Lynn, co-founder of the Montreal-based rooftop hydroponic greenhouse company, Lufa Farms. The two experts discussed differences in their company’s approaches to financing, business development, production, and sales outlets. When viewed side-by-side, the contrasting business models revealed unique opportunities and challenges, specific to each approach. The contrast was fascinating.
After the conference, attendees returned to Cuba, Germany, India, the U.S., and other home countries, to disseminate their freshly cultivated knowledge and excitement. I hope, as do countless others, for a second Urban Agriculture Conference in 2013.

the groundhog done it
It finally happened. While harvesting cherry tomatoes from my backyard garden earlier this week, a patch of topless broccoli plants caught the corner of my eye. Slowly turning to assess the damage – brow low, fists clenched – the reality became strikingly clear: my broccoli plants were completely decimated. Taking a step farther, I noticed that my beet greens were shorn to nibbly stumps as well.
How could this be?! Who was the culprit? One more step provided the answer: a groundhog done it. Marmota monax, little bugger. With a complete and utter lack of courtesy, this groundhog had made its home directly in the center of my peri-urban vegetable garden. There was nothing discreet about it. Main hole, back hole, emergency exit hole, all plain as day. Apparently in the eyes of a hungry rodent, it’s never too “city” for groundhogs.
After the initial shock and desire for revenge faded, I paused to consider the threat, or lack thereof, of rooftop vermin. Ground-level farms and gardens are often plagued by groundhogs, rabbits, and other fuzzy creatures looking for an easy meal. Growers spend time and money on poison, traps, fences, chemical deterrents, guard dogs, and even guns! But rather than removing the vermin from the garden, what if you were to remove the garden from the vermin? Rooftops offer a unique setting that is out of reach from groundhogs and rabbits. The occasional squirrel may wander up a downspout, but this can be easily prevented by installing metal collars at potential access points. As for mice and rats? Well, in the green roof industry we only really see these animals when the green roof is at-grade with the surrounding landscape. Elevate the roof, and 99 times out of 100, you’re safe.
Are your garden pests driving you crazy enough to try rooftop gardening?
containers and raised beds and pouches, oh my
In many developed nations we are both blessed and cursed with an obscene breadth of consumer choices. With a selection as simple as what type of cereal to buy: low fat, high fiber, whole grain, multi-color… decisions can quickly become daunting. Selecting planters for your home rooftop garden can conjure similar feelings of intimidation, and so here are a few quick steps to select your planters and grease your track to success:

step 1| Determine your garden’s objective. What prompted you to build a rooftop garden in the first place? Do you need herbs for cooking? Would you like to feed your family and friends throughout the summer? Defining your goals while considering the size and weight restrictions of your rooftop will start you off in the right direction. Honestly evaluating your lifestyle and how much time you can commit to watering, staking plants, and harvesting, will also help you determine what garden scale to pursue. For dainty installations, try focusing on containers and hanging pouches. If quantity is what you’re after, consider raised beds and self-watering containers.
step 2| Decide what crops to plant. This will be your garden. What vegetables and herbs will you enjoy eating and sharing with others? Each crop prefers a different soil depth, and the height of your planters should reflect these needs. Select shallow containers for shallow-rooted plants like greens and herbs, and deeper containers for crops like tomatoes, eggplant, and Brussel sprouts. Keep in mind that deeper soil means heavier planters, so be sure to consult a licensed structural engineer whenever a roof’s structural capacity is unknown.
step 3| Consider using recycled materials. Off-the-shelf planters can be quick and easy to install, but what if you’re trying to save a few bucks? Salvaging recycled materials, such as barrels, tins, even old bathtubs, can provide you with the planters you need, without the cost. Be smart about your selection by avoiding materials that could contaminate your soil, such as pressure treated wood, lead paint, or resins. Remember also that metal will rust and degrade quickly.
step 4| Let it drain! Regardless of whether you select containers, raised beds, hanging pouches, or recycled vessels, your planters must drain to prevent root rot. Most off-the-shelf containers are manufactured with at least one hole in the base, through which excess water is ushered. Metal containers do not contain drainage holes as consistently as ceramic and plastic pots, so drill or punch out several holes (with a hammer and nail) if none exists. Hanging pouches are generally made of felt or burlap cloth, both of which are permeable to water. For raised beds, try installing a hard plastic sheet drain with a high compressive strength (a common green roof component) underneath the frame to allow water to leave the bed.
What types of planters exist in your home garden? Are you happy with their performance?
