Imagine a world where the very ground beneath our feet is more valuable than the oil we drill for. Sounds radical, right? But that’s exactly what Wes Jackson, the visionary founder of the Land Institute, boldly declares: ‘Soil is more important than oil.’ This isn’t just a catchy phrase—it’s a call to action that could revolutionize agriculture as we know it. And it all starts with a simple yet profound idea: perennial grains.
In a humble greenhouse in rural Kansas, 100 unassuming plastic pots hold the promise of a greener future. Each pot contains a young perennial plant, its grass-like leaves swaying gently. Unlike annual crops like wheat, maize, or rice, these plants don’t die after a single season. They keep growing, year after year. But here’s where it gets controversial: could these perennials really replace the annual crops that feed the world? And this is the part most people miss—they’re not just about survival; they’re about thriving sustainably.
Lee DeHaan, a scientist at the Land Institute, is leading the charge. His mission? To transform intermediate wheatgrass into Kernza, a high-yielding perennial grain. Since 2010, DeHaan has been breeding Kernza to rival annual wheat, the world’s most widely grown crop. But why bother? Because annual agriculture, with its plowing and herbicides, is ‘the greatest disturbance on the planet,’ according to Tim Crews, the Institute’s chief scientist. It’s a system that erodes soil, pollutes water, and contributes to one-third of global greenhouse gas emissions.
Perennial grains, on the other hand, could be game-changers. They build soil health, reduce runoff, and store carbon. But there’s a catch: reliable, high-yielding perennial grains are still in their infancy. And this is where the debate heats up: Can we really depend on them to feed a growing population? Skeptics argue it’s too risky, while proponents see it as our best shot at sustainable farming.
The inspiration for this movement dates back to the 1970s when Wes Jackson visited a native prairie in Kansas. Prairies, with their deep roots and biodiversity, don’t erode soil—they enrich it. Jackson’s epiphany? Why can’t we grow grains like prairie plants? This question sparked a revolution that DeHaan, inspired as a teenager, has dedicated his life to answering.
Kernza is already making waves. Grown in 15 U.S. states, it’s found its way into beers, cereals, and even flour. But yields are still low—about one-quarter of annual wheat in Kansas. DeHaan, however, is optimistic. With advanced breeding techniques, he predicts Kernza could match wheat yields within 15 years. But here’s the kicker: Kernza’s roots go 3 meters deep, stabilizing soil and providing water even in droughts—benefits annual crops can’t match.
The Land Institute isn’t stopping at Kernza. They’re developing perennial oilseeds, pulses, quinoa, and more, with collaborators in 30 countries. From drought-tolerant sorghum in Uganda to low-input Kernza in war-torn Ukraine, the potential is vast. Yet, success isn’t guaranteed. Perennial rice in China, developed in just 20 years, proves it’s possible, but challenges remain.
DeHaan sees perennial grains as the key to balancing productivity, farm economics, and environmental impact—what he calls the ‘three-legged stool’ of sustainability. This isn’t just theory; it’s personal. His family’s Minnesota farm failed in the 1980s, despite high yields, due to economic pressures and environmental costs that went unaccounted for.
Today’s agriculture, DeHaan argues, is propped up by $600 billion in annual subsidies, often at the expense of farmers and the planet. Perennial grains could change that, but it won’t be easy. Yields must improve, harvests must stabilize, and markets must adapt. And this is where it gets really controversial: Are we willing to invest decades and millions of dollars into something that might not pay off immediately?
DeHaan doesn’t see the current agricultural system as the enemy. Instead, he believes it can evolve. The Land Institute’s strategy isn’t replacement—it’s redirection. Already, companies like General Mills are incorporating Kernza into their products, signaling a shift.
Back in that Kansas greenhouse, DeHaan reflects on how far they’ve come. Once laughed at, perennial grains are now taken seriously by researchers, businesses, and global partners. Those 100 young Kernza plants? Their descendants could feed millions while healing the soil. But here’s the question we must ask ourselves: Are we ready to rethink the very foundation of our food system? The soil—and our future—depends on it. What do you think? Is this the agricultural revolution we need, or is it too good to be true? Let’s discuss in the comments.
