The Great Glyphosate Debate

In a move that surprised many advocates of agricultural reform, the current administration invoked the Defense Production Act (DPA) to support domestic glyphosate production, designating it as critical to national supply chains. For supporters of the “Make America Healthy Again” (MAHA) movement, this decision feels like a step in the wrong direction.

The DPA has historically been used to strengthen domestic manufacturing during times of strategic vulnerability. Applying it to a widely used agricultural chemical signals that the federal government views glyphosate as essential to modern food production. But that raises an important question:

Is glyphosate truly indispensable, or have we built a system that depends on it because we have not invested seriously in alternatives?

For decades, glyphosate has been embedded into large-scale commodity agriculture. It plays two primary roles:

1. Weed control in herbicide-tolerant crop systems
2. Pre-harvest desiccation in certain crops like wheat and oats in colder climates

In 2015, the International Agency for Research on Cancer (IARC) classified glyphosate as “probably carcinogenic to humans.” Other agencies, including the U.S. EPA, have concluded it is unlikely to pose a cancer risk when used as directed; however, many of the studies showing it is safe are based on industry funded research and not truly independent research. The scientific debate remains active and politically charged.

Regardless of where one stands on toxicity, one fact is clear: Modern monocrop agriculture has become structurally dependent on chemical weed suppression.

The Role of Pre-Harvest Desiccation

One of the more controversial uses of glyphosate is as a pre-harvest desiccant in certain regions. Farmers may apply it shortly before harvest to dry crops evenly and improve harvest efficiency. So just before it is used for food production it gets an extra dose of glyphosate.

Eliminating it would not collapse wheat production, but in some regions it would increase harvest risk, drying time variability, and potential financial losses for the farmer.

If reform is the goal, we must acknowledge the logistical realities farmers face. The solution cannot be moral pressure alone it must include viable alternatives for the farmer or the consumer must demand change through their purchases.

Are Alternatives Realistic?

Emerging technologies such as AI-guided laser weeders, developed by companies like Carbon Robotics, demonstrate that non-chemical weed control is technologically possible. These systems use machine vision to identify and thermally destroy weeds without harming crops.

However, large-scale deployment faces barriers:

• Capital cost (often $1–2 million per unit)
• Scalability for broad-acre crops like wheat and corn
• Energy and operational tradeoffs

The technology is promising, but transitioning millions of acres requires investment, financing models, and policy alignment. Farmers are adaptable, but transitions must make economic sense.

A Systems-Level Alternative: Silvopasture and Soil Regeneration

If we look beyond incremental substitution, regenerative agriculture offers a structural alternative.

For example Silvopasture integrates crops like nut bearing or fruit bearing trees, forage, and livestock in one system. Properly managed, it can:

• Improve soil structure
• Increase biodiversity
• Enhance water retention
• Reduce reliance on synthetic fertilizers and herbicides
• Provide diverse food opportunities

Similarly, biochar, inspired by the ancient Amazonian “Terra Preta” soils, improves soil function not because it is inherently nutrient-dense, but because it enhances cation exchange capacity, microbial habitat, and long-term nutrient retention. When combined with compost and organic inputs, it can meaningfully improve soil fertility and resilience.

These approaches reduce chemical dependence by rebuilding soil health rather than compensating for its decline without the use of chemicals.

Why This Moment Matters

Designating glyphosate production as strategically critical signals that chemical-intensive monocropping remains the backbone of national food security strategy.

But long-term resilience may look different:

• More diversified cropping systems
• Integrated livestock
• Localized nutrient cycles
• Reduced input dependency
• Greater soil carbon storage
• Water-retentive landscapes

The debate over glyphosate is ultimately about something larger:

What kind of food system do we want to invest in for the next 50 years?

We can defend the status quo, or we can use this moment to accelerate the transition toward soil-centered, biologically resilient agriculture safe for everyone including farmer and end consumer. And above all, it requires treating soil as a living system worthy of restoration.
