It’s a bold statement, but step inside a humble greenhouse in rural Kansas, and you might start to believe it.
On the concrete floor sits a tidy grid of 100 plastic pots. Inside each pot, a tuft of strappy, grass-like leaves reaches upward, looking unremarkable to the untrained eye. But these aren’t ordinary plants. These are **perennials**—plants that grow year after year, without needing to be ripped up and replanted every season. And that single trait could transform agriculture as we know it.
Why? Because nearly every major grain crop we depend on—wheat, rice, maize, sorghum, barley, oats, soybeans—is an **annual**. Annuals complete their lifecycle in a single growing season. They sprout, grow, produce grain, and die. This cycle requires constant tilling, planting, fertilizing, and irrigation. It’s the backbone of global food production. But it’s also a root cause of massive soil degradation, water pollution, biodiversity loss, and carbon emissions.
Perennials, by contrast, stay rooted in place. Their deep, year-round root systems hold soil together, store carbon, access more water, and build long-term fertility. A field of perennial grain could feed people—and heal landscapes—at the same time.
That’s why researchers like **Lee DeHaan**, a plant breeder at **The Land Institute** in Salina, Kansas, see these scraggly plants as the future. “These plants are the winners, the ones that get to pass their genes on,” DeHaan says, gesturing at the quiet grid of pots. If his breeding program keeps achieving breakthroughs, the descendants of these young plants could one day spark a revolution bigger than the invention of synthetic fertilizer.
Welcome to the **perennial grain revolution**—where saving soil means transforming the very foundation of human agriculture.

## The Problem With Annuals: A 10,000-Year Legacy
To understand why perennial grains matter, it helps to rewind 10,000 years to the birth of agriculture. Early farmers in the Fertile Crescent selected seeds from annual grasses—plants that grew quickly, made large seeds, and could be harvested in bulk. It was a practical choice. Annual grains provided calories, could be stored, and were easy to domesticate.
But over millennia, this choice created an unintended dependency:
**Most of the world’s food calories now come from plants that require soil disturbance, fertilizer, and intensive management every single year.**
This system has consequences:
### **1. Soil Erosion**
Tilling strips soil of structure and exposes it to wind and rain. Globally, we lose an estimated 24 billion tons of fertile topsoil every year. Without soil, there is no food.
### **2. Carbon Emissions**
Soil is one of the planet’s biggest carbon sinks. Tilling releases carbon stored underground back into the atmosphere.
### **3. Chemical Dependency**
Annuals need fertilizers to grow quickly, herbicides to protect bare soil from weeds, and pesticides due to ecological imbalance. These chemicals pollute rivers, lakes, and oceans.
### **4. Water Waste**
Shallow-rooted annuals can’t access deep moisture, so they require more irrigation.
### **5. Biodiversity Loss**
Bare soil fields offer little habitat. Perennial systems, in contrast, support insects, birds, microbes, and mammals year-round.
In short, the global food system is built on plants that weaken the ecosystems that support them.
But what if our staple crops didn’t have to work that way?

## Meet Perennial Grains: The Roots of a Revolution
Perennial grains flip the script. Instead of dying after one season, they come back—year after year—just like prairie grasses or fruit trees. Their roots can reach depths of up to 10 feet or more, compared to 1–2 feet for most annual crops.
The benefits are dramatic:
* **Less erosion** because soil is always covered.
* **More carbon stored** deep underground.
* **Fewer fertilizers and chemicals** needed because plants access nutrients from deeper layers.
* **Improved water retention** and drought resilience.
* **Healthier soil biology** that builds over time instead of starting from scratch each spring.
This is what prompted Land Institute founder Wes Jackson to famously declare:
**“Soil is more important than oil.”**
Oil fuels our machines.
Soil fuels our species.
Lose oil, and we scramble.
Lose soil, and we starve.

## Kernza: The First Breakthrough
The most famous perennial grain to emerge from The Land Institute’s research is **Kernza**, a domesticated form of intermediate wheatgrass. Though not yet a full replacement for wheat, Kernza is already being grown on thousands of acres, baked into breads, brewed into beers, and used in cereals. Its taproots can reach astonishing depths, making it a champion of carbon sequestration.
But breeding perennial grains is slow, meticulous work—more like evolution guided by human hands than conventional crop breeding. It can take decades to select plants that have the right combination of traits: large seeds, predictable yields, disease resistance, and strong perennial regrowth.
That’s where DeHaan’s greenhouse comes in.

## Inside the Breeding Program
The Land Institute’s perennial grain program involves thousands of candidate plants. Each year, researchers evaluate which individuals show the traits needed for domestication:
* The biggest seeds
* The highest yields
* The toughest roots
* The strongest regrowth
* The most resilience against heat, drought, and pests
The “winners,” as DeHaan calls them, get to pass on their genes. Their descendants move one generation closer to an ideal: a grain that functions like wheat from aboveground but behaves like a prairie grass below it.
The process requires patience. Annuals can complete a breeding cycle every few months. Perennials take a year or more for each generation. But the payoff—an agriculture that restores instead of destroys—makes the wait worth it.

## Why Farmers Are Paying Attention
For farmers, perennial grains could shift the entire economic model of agriculture.
Instead of buying seeds and inputs every year, they could harvest from the same field for multiple seasons. Instead of losing topsoil, they could build it. Instead of chasing increasingly unpredictable weather patterns, they could grow crops with natural drought-hardiness.
In an era of climate uncertainty, perennial grains offer:
* Lower input costs
* Greater resilience
* More stable yields
* Regenerative soil health
It’s not wishful thinking. It’s practical survival.

## The Challenges Ahead
The biggest hurdle right now?
**Yield.**
Annual crops like wheat have been bred for thousands of years to produce enormous harvests. Perennial grains are still young in comparison. Their yields are lower—but rising.
The Land Institute, along with global partners in Australia, China, Europe, and Africa, is working to accelerate breeding using genetics, hybridization, and new technologies.
One day, perennial grains might feed billions.
But even now, they represent something deeper: a shift in how we view agriculture—not as an extractive industry, but as a living relationship between humans and land.

## A Quiet Revolution Underway
Back in the Kansas greenhouse, the pots sit quietly, each holding a small, green promise. These plants are humble. But so were the first wild grasses humans harvested thousands of years ago, long before civilization knew what agriculture would become.
Today, we stand at another turning point.
If oil shaped the last century, **soil will shape the next**.
And perennial grains—deep-rooted, resilient, restorative—may be the key to ensuring that the ground beneath our feet stays alive for generations to come.
The revolution isn’t loud.
It’s growing quietly in plastic pots, greenhouses, and prairie fields.
Year after year.
Root by root.
Plant by plant.
And it begins with the radical idea that farming can heal the Earth instead of exhausting it.
