A no-till seeder at work on a long-term conservation agriculture (CA) trial plotPhoto: International Maize and Wheat Improvement CenterConservation is an important part of federal farm funding -- the laws that shape what, where, and how we grow our food. And yet, if the negotiations around the 2012 Farm Bill go as predicted, funding for conservation is in grave danger. Why does conservation on farms matter? Well, for starters, most large-scale agriculture is a disruptive endeavor. It requires farmers to plow under native flora and replace it with giant monocultures of annual crops, and then coddle those crops by irrigating …

All cattle, no hats.Photo: Rob CrowA sea of cream-colored cowboy hats, the kind ranchers wear on their days off, fills a sterile conference room at the Fort Collins Marriott. Banners from groups like the Ranchers-Cattlemen Legal Action Fund and the Western Organization of Resource Councils add bright slashes of color, and warn that JBS, the world's largest meatpacker, now controls 24 percent of all cattle produced in the United States. It's August 2010, the night before a national workshop on competition in the livestock industry, and well over 500 ranchers, feedlot owners, and their allies are packed into this room …

Photo: Mark Kjerland & super.heavy via flickrTalk with healthy-food advocates in urban centers across the country, and frequently, you'll hear the same story. It goes something like this: Once upon a time, this city was full of grocery stores. Then came urban renewal/an economic downturn/a mass exodus of the wealthy and, one by one, the groceries closed up and moved to the outskirts of the city. Since then, there have been Safeways/Krogers/Publix that have set up shop here and there, but they all end up leaving. Now we have 100 liquor stores for 25,000 people in this part of town, …

One of City Slicker Farms’ tiny but productive sites in West Oakland, California. Much of the produce is grown vertically, to maximize space, and there’s a chicken coop tucked in the back corner. Photo courtesy of Anne Hamersky, from the forthcoming book Farm Together Now Giant cranes guard the waterfront on the port city of Oakland, California's western flank, brashly broadcasting the city's industrial past and present to all who fly in, drive by, or walk through one of the Bay Area's grittiest urban locales. Yet in the same West Oakland neighborhoods that boast industrial diesel pollution from the bustling …

California dairy farmer Joey Rocha. Photo: Stephanie OgburnTurlock, Calif. -- Joey Rocha tends 2,800 cows at his Central Valley dairy. That may sound like a large herd, but in California, Rocha is a mid-sized dairy producer. Taken together, California's dairy cows produce more than 100,000 tons of manure every day. Rocha and his fellow dairy farmers put all those cow pies to good use -- as fertilizer for the fields that grow the corn that feeds their herds. It's a perfect closed-loop system, except for one big problem: nitrogen. Manure is nitrogen rich, which makes it a great fertilizer. But …

Few people spare a thought for nitrogen.  But with every bite we take -- of an apple, a chicken leg, a leaf of spinach -- we are consuming nitrogen. Plants, including food crops, can't thrive without a ready supply of available nitrogen in the soil. The amount of food a farmer could grow was once limited by his or her ability to supplement soil nitrogen, either by planting cover crops, applying manure, or moving on to a new, more fertile field. Then, about 100 years ago, a technical innovation enabled us to produce a cheap synthetic form of nitrogen, and …

Cows on pasture: potential solution, or menace to society? What is just food? One might answer: food produced without causing undue ecological damage, food grown under production systems that allow workers and farmers to earn livable wages, food that's healthy, accessible, and affordable to everyone who eats. To James E. McWilliams, author of the new book Just Food: Where Locavores Get It Wrong and How We Can Truly Eat Responsibly, just food is certainly much more than food produced and purchased locally, and his book wags a contrarian finger at the "locavores" who believe purchasing food grown close to home …

We've all heard that eating locally is one way to reduce your environmental impact. But what about donating locally? In the urban wilds of New York City, a new non-profit is betting that locally based, small-scale giving can have a big eco-impact. Ioby, whose name stands for "in our back yards," connects people working on neighborhood-level projects with community members who can physically and financially support them. At ioby.org, launched this month by co-founders Erin Barnes, Cassie Flynn, and Brandon Whitney, individuals or groups post project descriptions and budgets, and interested donors contribute to the project of their choice. Here's …

Photo courtesy of M J M, via FlickrAs the good food movement matures, its members have begun discussing its inclusiveness. This week, at the W.K. Kellogg Foundation’s ninth Food and Society Conference, speaker after speaker touched upon the topic of race and access to good food.  “Who is at the table?” asked Anim Steel, Director of National Programs for The Food Project, a Boston-based organization that works to engage youth in sustainable agriculture. Steel’s rhetorical question referred to a growing conversation among members of the sustainable food movement about helping the movement grow and include all people, not just those …

In "Dispatches from the Fields," Ariane Lotti and Stephanie Ogburn, who are working on small farms in Iowa and Colorado this season, share their thoughts on producing real food in the midst of America's agro-industrial landscape. ----- In the past few weeks, I've had the opportunity to attend a couple of events here in southwestern Colorado sponsored by the state and federal governmental agriculture agencies. Taxpayer-funded ag technicians showed off impressive new methods of irrigation and water management. They also demonstrated their commitment to the standard ag paradigm: maximizing yield of industrial inputs -- e.g., crops that produce seeds that …
