The agricultural landscape in Canada is facing significant upheaval as the ongoing instability in the Strait of Hormuz threatens to disrupt global fertiliser supplies crucial for spring farming. This vital waterway, which facilitates one-third of the world’s trade in fertilizers and energy, is currently under threat from Iranian military actions, leading to concerns about the availability and affordability of essential nutrients for crops as planting season approaches.
Strait of Hormuz: A Crucial Trade Route
The Strait of Hormuz is one of the world’s most critical maritime chokepoints, allowing passage for a substantial portion of global energy and fertiliser shipments. According to Kreg Ruhl, vice-president of crop nutrients at Growmark, this narrow channel is indispensable for the transport of key fertiliser components, including urea, nitrogen, sulphur, and phosphates. The ongoing conflict in the Middle East has raised fears of prolonged closures, which could have dire implications for agricultural producers across North America.
“The entire world is competing for the limited supply that’s available,” Ruhl stated. With farmers in North America preparing to plant their crops in the next month or two, the timing of these disruptions couldn’t be worse.
Fertiliser Price Increases on the Horizon
Canadian farmers are already feeling the pinch of rising fertiliser prices, which have surged dramatically in recent months. Philip Rumley, who operates North Rumley Farm in Alberta, indicated that costs for urea may reach as high as $1,200 per tonne. “If you haven’t bought your fertiliser by now, because we’re within a month of go time, you’re going to be in trouble,” he warned, highlighting the urgency of the situation.

In addition to potash—which Canada excels in producing, accounting for 32.8 per cent of the world’s supply—the production of fertiliser also relies heavily on nitrogen and other nutrients that are not sourced domestically. Ryan Flitton, co-owner of Twin Valley Farms in Ontario, emphasised that the reliance on imported fertilisers poses a significant challenge for Canadian agriculture. “Most of the fertilisers that we produce in Canada are for export markets,” he noted, adding that the country consumes a substantial amount of imported products.
Economic Strain on Farmers
The volatile fertiliser market is just one of the many challenges facing Canadian farmers. Ruhl pointed out that the ongoing economic difficulties in agriculture, characterised by negative ‘farmgate’ economics, compound the issue. Higher input costs can severely impact the financial viability of farms already struggling to maintain profitability.
Mike von Massow, a food economist at the University of Guelph, echoed these concerns, noting that disruptions could also affect freight rates, particularly for liquefied natural gas and crude oil shipments to Eastern Canada. The cascading effects of the Strait’s instability could ripple through various sectors of the economy, intensifying the challenges for farmers and consumers alike.
A History of Challenges
This is not the first time Canadian fertiliser suppliers have faced significant hurdles. Recent tariff threats from the U.S., which could add further strain to the industry, highlight the volatility of the market. Despite these uncertainties, Nutrien—a major player in crop inputs—has projected stable sales for potash this year, expecting volumes between 14.1 million and 14.8 million tonnes.

As the planting season approaches, the demand for fertilisers peaks, which adds pressure to an already precarious situation. Ruhl explained that while the Eastern Canadian market primarily relies on spring fertilisation, nitrogen products are particularly vulnerable to supply disruptions from the Strait of Hormuz.
Why it Matters
The potential fallout from the ongoing conflict in the Strait of Hormuz is poised to have far-reaching implications for Canadian agriculture. With farmers already grappling with rising costs and supply chain uncertainties, the possibility of fertiliser shortages could threaten crop yields and agricultural output, ultimately impacting food prices for consumers. As the situation evolves, stakeholders in the agricultural sector must remain vigilant and proactive to mitigate the risks posed by these global disruptions.
