Agicultural Sanity for A Change
Future Farming By ROBERT JENSEN
As everyone scrambles for a solution to the crises in the nation’s economy, Wes Jackson suggests we look to nature’s economy for some of the answers. With everyone focused on a stimulus package in the short term, he counsels that we pay more attention to the soil over the long haul.“We live off of what comes out of the soil, not what’s in the bank,” said Jackson, president of The Land Institute. “If we squander the ecological capital of the soil, the capital on paper won’t much matter.”
Jackson doesn’t minimize the threat of the current financial problems but argues that the new administration should consider a “50-year farm bill,” which he and the writer/farmer Wendell Berry proposed in a New York Times op/ed earlier this month.
Central to such a bill would be soil. A plan for sustainable agriculture capable of producing healthful food has to come to solve the twin problems of soil erosion and contamination, said Jackson, who co-founded the research center in 1976 after leaving his job as an environmental studies professor at California State University-Sacramento.
Jackson believes that a key part of the solution is in approaches to growing food that mimic nature instead of trying to subdue it. While Jackson and his fellow researchers at The Land Institute continue their work on Natural Systems Agriculture, he also ponders how to turn the possibilities into policy. He spoke with me from his office in Salina, Kansas.

Washing Away
Soil Erosion Worse than Ever and Still Increasing
Our Good Earth
The future rests on the soil beneath our feet.

On a warm September day, farmers from all over the state gather around the enormous machines. Combines, balers, rippers, cultivators, diskers, tractors of every variety—all can be found at the annual Wisconsin Farm Technology Days show. But the stars of the show are the great harvesters, looming over the crowd. They have names like hot rods—the Claas Jaguar 970, the Krone BiG X 1000—and are painted with colors bright as fireworks. The machines weigh 15 tons apiece and have tires tall as a tall man. When I visited Wisconsin Farm Technology Days last year, John Deere was letting visitors test its 8530 tractor, an electromechanical marvel so sophisticated that I had no idea how to operate it. Not to worry: The tractor drove itself, navigating by satellite. I sat high and happy in the air-conditioned bridge, while beneath my feet vast wheels rolled over the earth.
The farmers grin as they watch the machines thunder through the cornfields. In the long run, though, they may be destroying their livelihoods. Midwestern topsoil, some of the finest cropland in the world, is made up of loose, heterogeneous clumps with plenty of air pockets between them. Big, heavy machines like the harvesters mash wet soil into an undifferentiated, nigh impenetrable slab—a process called compaction. Roots can't penetrate compacted ground; water can't drain into the earth and instead runs off, causing erosion. And because compaction can occur deep in the ground, it can take decades to reverse. Farm-equipment companies, aware of the problem, put huge tires on their machines to spread out the impact. And farmers are using satellite navigation to confine vehicles to specific paths, leaving the rest of the soil untouched. Nonetheless, this kind of compaction remains a serious issue—at least in nations where farmers can afford $400,000 harvesters.
Our species is rapidly trashing an area the size of the United States and Canada combined.
