Lately there has been plenty of press about how we can use gardening to enrich our lives — from building communities, to making the places we live more beautiful. The local food movement has taken off locally, as well as nationally, and more and more people in Richmond and across the nation people are focusing on gardening as a whole.

Here at Lewis Ginter, as part of our 25th anniversary celebration funded by the Robins Foundation, we are getting ready to host a symposium on this very topic Green Tonic: Urban Gardening for Health & Wholeness, Aug 4-5. We will have leaders from the cities that have set the stage in the urban gardening movement — Chicago, Philadelphia and New York City, looking at the policies and practices that help those cities succeed; and what Richmond area residents can do to take urban gardening and greening in our community to the next level.  Registration is NOW open!

The line-up is stellar:

• LaDonna Redmond, President and CEO Institute for Community Resource Development, Chicago

• Pennsylvania Horticultural Society’s Philadelphia Green Program

Blaine Bonham, Executive Vice President

Joan Reilly, Senior Director, Philadelphia Green

Maitreyi Roy, Vice President for Programs

• Drew Becher, Director, New York Restoration Project, New York

• Timothy Beatley, Heinz Professor of Sustainable Communities

University of Virginia, Charlottesville

• Leni Sorensen, African-American Research Historian, Monticello, Charlottesville

• Rachel Flynn, Director, Department of Community Development, Richmond

Workshops:

• Basics of Sustainable Gardening
• Urban Greening for a Robust Economy
• Creating Greener, More Resilient Communities
• Sustainable Land Use and Water Quality Management
• Food Security, Access, Nutrition, and Health

Look at these amazing things that have been happening in the urban gardening movement right her in Richmond, in Virginia,and across the nation!  It is so exciting that Richmond is on the cutting edge of this movement.  You won’t want to missGreen Tonic: Urban Gardening for Health & Wholeness.

In Richmond, this Saturday, July 11th at 4 pm and 11 pm,  Movieland, is showing a new movie FOOD,Inc about  your food’s journey from the land to the table.   After the event,WholeFoods is sponsoring a panel discussion and food tastings.

In Staunton, the Stonewall Jackson Hotel is using a rooftop garden to grow produce for their hotel’s restaurant in order to expand their menu offerings, go green and offer the freshest produce available. The cost: about $200, but the expect to harvest 400 tomatoes and 20lbs of peppers! So that is VERY cheap.

“It’s all about the quality, and again this is why we’re doing this to deliver the best quality we can to our guests,” said the hotel’s executive chef, David Hamilton.

The initiative is designed to be a low-cost, high quality alternative to trucking in produce from out of town.

Hamilton says he plans to have much of what he’s growing go from the garden to the dinner table quickly, “Super fresh, it won’t get any fresher–as a matter of fact in some instances it will be just minutes before, between the time the product is picked and actually served.”

The rooftop garden uses water from the hotel’s air conditioning unit to care for the vegetables.

And on the National Mall, in Washington, D.C., the USDA just announced “Healthy Garden” workshops at the People’s Garden. Check this out:

“In many ways, USDA’s ‘People’s Garden’ is the nation’s demonstration plot, showing how small steps can mean important gains in mitigating global warming and producing a safe, sustainable and nutritious food supply,” said Vilsack. “The garden concepts we’re teaching this summer can be your contribution to providing healthy food, air, and water for people and communities across the country.”

Each workshop will provide an interactive demonstration of various aspects of ‘The People’s Garden,’ teaching practical skills on how to grow a garden in any set-up, from window boxes to acre plots.

The “Healthy Garden” Workshop Series schedule and topics include:

• June 26 – Gardening From the Ground Up: Improving Your Soil
• July 3 – Watering Your Lawn and Garden
• July 10 – Make-Up Day #1
• July 17 – Container Gardening and Window Boxes
• July 24 – Weeding and Removing Invasive Plants
• July 31 – Installing and Using Rain Barrels
• August 7 – Make-Up Day #2
• August 14 – Attracting Pollinators: Friends of Healthy Gardens
• August 21 – Inviting Wildlife with Bat Boxes and Other Backyard Habitats
• August 28 – Maximizing Your Harvest
• September 4 – Make-Up Day #3
• September 11 – Making and Using Compost
• September 18 – Choosing and Using Fertilizers
• September 25 – Fall Maintenance: Preparing Your Garden for Next Season

Microbes Will Feed the World, or Why Real Farmers Grow Soil, Not Crops

http://modernfarmer.com/2014/04/microbes-will-feed-world-real-farmers-grow-soil-crops/

Out on the horizon of agriculture’s future, an army 40,000 strong is marching towards a shimmering goal. They see the potential for a global food system where pesticides, herbicides and fertilizers are but relics of a faded age.

They are not farmers, but they are working in the name of farmers everywhere. Under their white lab coats their hearts beat with a mission to unlock the secrets of the soil — making the work of farmers a little lighter, increasing the productivity of every field and reducing the costly inputs that stretch farmers’ profits as thin as a wire.

‘Producing more food with fewer resources may seem too good to be true, but the world’s farmers have trillions of potential partners that can help achieve that ambitious goal. Those partners are microbes.’

The American Society of Microbiologists (ASM) recently released a treasure trove of their latest research and is eager to get it into the hands of farmers. Acknowledging that farmers will need to produce 70 to 100 percent more food to feed the projected 9 billion humans that will inhabit the earth by 2050, they remain refreshingly optimistic in their work. The introduction to their latest report states:
“Producing more food with fewer resources may seem too good to be true, but the world’s farmers have trillions of potential partners that can help achieve that ambitious goal. Those partners are microbes.”

Mingling with Microbes

Linda Kinkel of the University of Minnesota’s Department of Plant Pathology was one of the delegates at ASM’s colloquium in December 2012, where innovators from science, agribusiness and the USDA spent two days sharing their research and discussing solutions to the most pressing problems in agriculture.
“We understand only a fraction of what microbes do to aid in plant growth,” she says. “But the technical capacity to categorize the vast unknown community [of microorganisms] has improved rapidly in the last couple of years.”
Microbiologists have thoroughly documented instances where bacteria, fungi, nematodes — even viruses — have formed mutually beneficial associations with food plants, improving their ability to absorb nutrients and resist drought, disease and pests. Microbes can enable plants to better tolerate extreme temperature fluctuations, saline soils and other challenges of a changing climate. There is even evidence that microbes contribute to the finely-tuned flavors of top-quality produce, a phenomenon observed in strawberries in particular.
“But we’re only at the tip of the iceberg,” says Kinkel.

In the Field

Statements such as, “There are 10 to the 6th fungal organisms in a gram of soil!” and, “This bacterial biofilm has tremendous communication properties!” are breakroom banter among microbiologists, but what does it all mean for farmers? The answers reach back into the millennial past of agriculture, back to the dawn of life on earth.
Whenever a seed germinates in the wild or a crop is planted by a farmer, the microbial community that helps that species to grow and thrive is mobilized. Chemical signals enter the soil via the exudates of the plant and a symphony of underground activity commences. Genetic information is exchanged; the various microbial players assume their positions on the tissues of the plant; often, one microbe colonizes another, providing a service that helps the first microbe to assist the plant whose roots it is embedded in.
Though this elaborate dance takes place without any input from humans, we have been tinkering with it for a long time.
For example, the process of nitrogen fixation in plants of the legume family (which includes beans, peas, peanuts and many other crop plants) is one of the little bacterial miracles that makes our planet habitable. Anyone who has ever observed the roots of a legume knows that they are covered in strange white or pinkish growths, about the size of ants, which appear to be an infection of some sort. Undoubtedly, ancient farmers had an intuitive understanding that these warty protuberances had something to do with the noticeable ability of legumes to improve the soil, but it wasn’t until the late 19th century that the mystery began to unfold.
While Louis Pasteur was discovering how to preserve milk and becoming famous as the father of microbiology, a relatively unknown colleague of his with a penchant for plants was making another discovery, of perhaps even greater historical importance. In 1888, Martinus Beijerinck, discovered that tiny bacteria called Rhizobia infect the roots of legumes, causing the swollen nodules. Rather than an infection that weakens the plant, the nodules are the fertilizer factories of the plant kingdom, disassembling atmospheric nitrogen — which plants are unable to use — and refashioning it in a soluble, plant-friendly form.
Rhizobia are key ingredients of the earth’s verdancy and harnessing the bacteria to improve soil fertility has long been one of the cornerstones of sustainable agriculture. Yet, modern day microbiologists are now aware of scores of other equally profound plant-microbe interactions, discoveries they believe will have a big impact as human populations continue to soar on a planet of finite resources.

Making the Translation

In her lab at the university, Kinkel experiments with antibiotic bacteria that suppress plant pathogens and tests various soil management strategies to see their effects on microbial communities. In Colombia, microbiologists have learned to propagate a fungus that colonizes cassava plants and increases yields up to 20 percent. Its hyphae — the tiny tentacles of fungi — extend far beyond the roots of the cassava to unlock phosphorus, nitrogen and sulfur in the soil and siphon it back to their host, like an IV of liquid fertilizer.

Though microbiologists can coerce soil to produce extraordinary plant growth in their labs and test plots, transferring the results to everyday agricultural practices is not a straightforward process.
“Connections to farmers are a weak link,” Kinkel laments, alluding to a “snake oil effect” where farmers have become leery of salesmen hawking microbial growth enhancers that don’t pan out in the field. “The challenge of [these] inoculants,” she says, “is they may not translate in all environments.”
Though researchers continue to develop promising new microbial cocktails, there is an increased focus on guiding farmers to better steward the populations that already exist in their soil. Kinkel is working on an approach she believes will help farmers sustain optimal microbial communities by ensuring they have the food they need — carbon — at all times. She calls it ‘slow release carbon’, but it’s not something farmers will see in supply catalogs anytime soon. Kinkel says she has access to resources for her academic research, but lacks a “deliberate pipeline for product development.”

It Takes a Global Village

The 26 experts from around the world convened at the ASM colloquium concluded their discussions with a bold goal for the future of agriculture: They’ve challenged themselves to bring about a 20 percent increase in global food production and a 20 percent decrease in fertilizer and pesticide use over the next 20 years.
With an indomitable belief that science will do its part to make this dream a reality, the scientists are looking to their corporate and regulatory counterparts to build a pipeline of information to farmers. They’re hoping that top-down investments in research and technology will meet directly with grassroots changes in the culture of farming — without all the snake oil-vending agribusiness interests in the middle. Ultimately, they envision a future where farmers again trust in the unseen forces of the soil — instead of the fertilizer shed — for answers to their challenges.
