Opinion: The engineering case for distributed U.S. fertilizer production

For decades, fertilizer manufacturers evaluated granulation capacity primarily through the lens of economics: capital costs, operating efficiency, throughput and return on investment. Today, that framework is incomplete. Distributed granulation capacity has become a matter of agricultural resilience, supply chain security and national economic stability.

Granulation is the critical process that transforms fertilizer intermediates into stable, transportable and application-ready products. When granulation capacity is concentrated in a handful of facilities or regions, the entire supply chain becomes vulnerable to disruption. A hurricane, power outage, labor strike, cyberattack, transportation bottleneck or geopolitical conflict can remove significant production volume from the market with little warning.

Recent events have demonstrated that supply disruptions are not isolated anomalies.

They are recurring features of the modern industrial landscape. The COVID-19 pandemic strained production and logistics networks. Global shipping disruptions exposed vulnerabilities in just-in-time supply chains. The Russia-Ukraine conflict sent fertilizer prices soaring worldwide. More recently, rising tensions in the Middle East have highlighted another critical vulnerability: the concentration of global fertilizer exports in the Persian Gulf region.

The fertilizer industry's exposure to the Strait of Hormuz illustrates the scale of this risk. In 2024, an estimated 30% of global fertilizer trade passed through this narrow maritime corridor. Between 2023 and 2025, Gulf nations accounted for approximately 36% of global urea exports. Disruptions from military conflict, shipping restrictions, infrastructure attacks or geopolitical instability can immediately affect global fertilizer availability and pricing. For American farmers, the result is familiar: reduced market certainty, increased pressure on operating margins, higher input costs and an increasingly bleak outlook.

This dependence on distant supply chains means that fertilizer markets increasingly respond to events occurring thousands of miles from U.S. farmland. A disruption in the Strait of Hormuz can influence fertilizer prices in Iowa, Kansas, Nebraska or California within days. The issue is no longer simply one of trade efficiency; it is one of strategic vulnerability.

Distributed granulation capacity offers a practical solution. By expanding domestic and regional production networks, manufacturers can create redundancy throughout the fertilizer supply chain. A distributed system reduces dependence on single facilities, transportation corridors, ports and overseas suppliers. It also provides greater flexibility to adapt to market disruptions, regional demand shifts and unforeseen emergencies.

Beyond improving resilience, distributed granulation capacity gives fertilizer manufacturers a level of operational flexibility that centralized production simply cannot match. Regional granulation facilities can be strategically positioned near feedstock sources, transportation hubs and major agricultural markets, reducing dependence on long-haul transportation networks and minimizing the impact of localized disruptions.

Distributed facilities also allow manufacturers to respond more quickly to changing customer requirements. As crop patterns, nutrient demands and environmental regulations evolve, regional plants can adjust formulations and production schedules to meet local market needs. This agility becomes increasingly valuable during periods of market volatility, when growers may require different nutrient blends or delivery timelines than originally forecast.

From an engineering perspective, distributed granulation networks can also improve overall system utilization. Rather than relying on a few large facilities operating at maximum capacity, manufacturers can balance production across multiple sites, reducing bottlenecks and creating redundancy for maintenance outages or unexpected downtime. This approach helps maintain consistent product availability while reducing the risks associated with single points of failure.

Most importantly, distributed granulation capacity transforms fertilizer manufacturing from a linear supply chain into a resilient production ecosystem. In an era of geopolitical uncertainty, transportation constraints and climate-related disruptions, this kind of flexibility is an operational requirement for ensuring reliable nutrient supplies for agriculture.

Like the electrical grid, the fertilizer industry benefits from redundancy. No engineer would design a national power system around a single generating station. Yet, fertilizer production and processing remain heavily concentrated despite serving a resource that is equally essential to national well-being! Food production depends on reliable access to nitrogen, phosphorus and potassium. When fertilizer supply is disrupted, the effects ripple through crop yields, food prices, export markets, and ultimately, consumers. However, production location is a key point of consideration.

Modern engineering makes distributed production increasingly viable. Advances in granulation technology, modular plant design, automation, and bulk material handling enable efficient operations at multiple scales. These scalable technologies allow manufacturers to strategically locate production closer to agricultural demand centers while maintaining competitive economics.

Resilience is a core engineering requirement, and with the ability to implement turnkey, scalable production facilities, proactive measures can be taken.

Distributed granulation capacity should therefore be viewed as critical infrastructure. It is an investment not only in fertilizer production, but in agricultural security, economic stability and the long-term resilience of the American and international food systems.
