Ag Minute: 250 Years of the American Farmer

This Fourth of July marks 250 years since the United States declared itself an independent nation. It has been a remarkable quarter-millennium, shaped by exploration, innovation, and the hard work of the men and women who built what we get to enjoy today. But the backbone of the country over these 250 years has been farmers, whose work has sustained so much of American life. To examine the story of the farmers who helped build this country, we must first look to a time before there was ink on the Declaration of Independence.
Before America was America, Native peoples had already developed a strong understanding of how to work with the soil. Indigenous communities grew corn, beans, and squash together in a system often called the Three Sisters. More than just a way to grow food, this system was a lesson in balance between crops and was taught by natives to some of the early colonists.
Through the 17th and 18th centuries, farming became much more than an occupation. It was the condition of American life. By the time of the Revolution, the fields, gardens, orchards, pastures, and plantations of the colonies fed families, supplied markets, and shaped politics. Many of the men who argued for independence were men of the land, though they came to that cause from different regions and experiences. George Washington kept careful farm records at Mount Vernon, while Thomas Jefferson wrote often about farming, soil, and the promise of an agrarian republic.
But that story cannot be told honestly without recognizing who carried much of its weight. In the South especially, a large part of the agricultural economy was built on the labor of enslaved people. That painful contradiction sat beside the nation’s founding ideals and helped shape the tensions that would eventually lead to America’s Civil War.
Amid the Civil War, agriculture was still moving west. The frontier became a plow cutting into prairie sod and a few acres of possibility for hardworking families willing to try their hand at it. The Homestead Act of 1862 opened millions of acres to settlement and helped shape the Great Plains into one of the great agricultural regions of the world. For many families, it offered opportunity, and to this day, many families still farming the Plains trace their roots to the homestead era.
Then came the machines.
In the heavy soils of the Midwest, John Deere’s steel plow helped farmers break ground that older tools struggled to handle. In the grain fields, Cyrus McCormick’s reaper changed harvest forever, allowing crops to be gathered far more efficiently. These inventions did more than make farming easier. They changed the structure of American life. As farms became more productive, fewer people were needed to produce food, and more Americans could build railroads, teach school, open shops, work in factories, practice law, preach sermons, and eventually enter careers that would have been impossible without a dependable food supply beneath them.
Here in Illinois, that story sits close to home. Deere’s work in Grand Detour and the rise of Midwestern machinery were not side notes in American history. They were part of the reason the prairie became an engine of production.
But American farmers were never shaped by machinery alone. They were also shaped by knowledge. In 1862, with a nation torn apart, Abraham Lincoln signed the Morrill Act, laying the foundation for land-grant universities devoted to agriculture and the mechanic arts. From those institutions came research, Extension, soil science, plant breeding, veterinary medicine, hybrid seed, conservation practices, and farm management tools that helped define modern agriculture. In time, American farmers became more than laborers of the land. They became part mechanic, part scientist, part economist, and part weatherman, carrying forward both inherited wisdom and the research needed to produce more with less.
For generations, American agriculture had been defined by movement forward: better tools, better seed, better schools, and better ways to turn land into abundance. But progress in agriculture has never erased dependence on nature. No matter how advanced the plow, the planter, or the research behind them became, farmers still worked at the mercy of soil, rain, wind, and weather. In the 1930s, that reality came with devastating force.
The Dust Bowl turned parts of the Great Plains into a warning. Soil that had taken centuries to build was lifted by wind and carried across the sky. Farms failed. Families left. The same land that had promised independence now revealed the danger of treating soil as endless.
Then came the Green Revolution. Led by people like Iowa-born plant scientist Norman Borlaug, American agricultural science was no longer changing only America. By helping develop high-yielding wheat varieties used in places like Mexico, India, and Pakistan, Borlaug helped make the American agricultural tradition part of a larger global story, where seed, science, and determination moved millions of people further from hunger and closer to stability.
And yet, for all the scale, all the machinery, and all the technology, American agriculture remains deeply personal.
Today, the United States has fewer farmers than it once did, but those farmers carry more responsibility than ever. Less than 2% of the population operates across hundreds of millions of acres, producing food, fuel, and fiber for a nation that often sees the finished product but not the hands behind it. Modern farmers use GPS, cutting-edge genetics, data, satellites, global markets, and machines that would have seemed impossible to earlier generations. But the old uncertainties remain. Rain still matters. Markets still move. Livestock still need care. A crop can still look perfect in June and be humbled by August.
Over 250 years, American agriculture has helped build a country from what started as frontier outposts, prairies, river bottoms, and mountain valleys. It has fed armies, cities, schoolchildren, factory workers, and families gathered around holiday tables. It has made possible the growth of industries that seem far removed from the farm, because every society must first answer the oldest question: who will provide the food?
The story of America cannot be told without farmers. Not because agriculture is quaint or nostalgic, but because it is foundational. Before the skyscraper, there was the field. Before the factory whistle, there was the morning chore. Before a nation could dream of liberty, industry, invention, or power, someone had to plant, tend, harvest, and feed it.
For 250 years, the American farmer has done just that.
