Nutrien and the Potash Business: How Saskatchewan Feeds the World

Saskatchewan feeds the world not by growing food but by selling the mineral that makes everyone else’s soil productive, and Nutrien is the company through which most of that trade flows. Potash is a simple product, potassium chloride dug from evaporite beds a kilometre underground, but the business around it is unusually concentrated: a handful of producers in Canada, Russia and Belarus, an export agency that has set offshore prices since 1972, and a customer base of farmers whose demand depends on crop prices, credit and, since 2025, tariffs. This article explains how Nutrien came to exist, how the potash and retail businesses interlock, what the arrival of BHP means, and what the 2025 and 2026 results say about the cycle. It is part of the Canada Company Stories hub.

How did Nutrien come to exist?

Nutrien was created by the merger of Potash Corporation of Saskatchewan and Calgary-based Agrium, which closed on 1 January 2018 after regulators in Canada, the United States, China and India had cleared it. Former PotashCorp shareholders received 52 per cent of the combined company and Agrium’s 48 per cent, and the new entity began life with a market value of about US$34 billion and headquarters in Saskatoon, with a corporate office kept in Calgary. The deal joined the largest potash producer in the world to the largest agricultural retailer in North America, and the combination has defined the company ever since.

PotashCorp’s own history explains why the province dominates the industry. The Saskatchewan government nationalised a large part of the potash sector in 1975, created a Crown corporation to run it, and privatised that corporation in 1989; PotashCorp inherited the Rocanville, Allan, Cory, Lanigan, Patience Lake and Vanscoy mines, which sit on the Prairie Evaporite formation that holds the largest and highest-grade potash deposits on earth. In 2010 BHP Billiton bid about US$38.6 billion for PotashCorp, and the federal government blocked the offer under the Investment Canada Act on the grounds that it would not be of net benefit to Canada; BHP withdrew rather than accept the conditions offered. That decision kept the company Canadian and, fifteen years later, pushed BHP to build its own mine instead.

Agrium brought the other half of the business. Starting from a nitrogen plant in Alberta, Agrium had built a chain of farm-supply stores across the United States, Canada, Australia and South America, selling fertiliser, seed and crop-protection chemicals directly to growers. In a merger pitched as a US$36 billion agricultural colossus, the logic was that mining margins are cyclical and retail margins are stable, so a company with both would have steadier cash flow than either partner alone. Chief executive Ken Seitz, a PotashCorp veteran who took over in 2022, has run the company on that premise since.

How does the potash business actually make money?

Potash profit depends on three variables: volume, price and the cost of getting the product from the mine to the farm. Nutrien’s six Saskatchewan mines give it more volume flexibility than any competitor, because it can run them well below capacity in a weak market and bring tonnes back quickly when demand recovers. In the first half of 2026 the company produced 7.66 million tonnes and sold a record 7.45 million, up from 7.39 million a year earlier, and raised its full-year sales guidance to 14.2 to 14.8 million tonnes against a forecast of 74 to 77 million tonnes of global shipments.

Price is set in two very different markets. In North America, where Nutrien sells directly and the product moves by rail, the average realised price in the second quarter of 2026 was US$295 a tonne. Offshore, where every tonne goes through Canpotex, it was US$259. The blended figure of US$267 compared with US$248 a year earlier, and the half-year average of US$266 was up from US$235, a recovery from the 2023 and 2024 trough that followed the price spike after Russia’s invasion of Ukraine in 2022. Sanctions on Belarus and disruption to Russian exports had pushed potash above US$1,000 a tonne in mid-2022; the return of those tonnes to the market drove prices down by more than two-thirds over the following eighteen months.

Cost is where Nutrien’s advantage is structural rather than cyclical. Its controllable cash cost of product manufactured was US$55 a tonne in the second quarter of 2026 and US$57 for the half, below the company’s US$60 target and far beneath the operating cost of newer or deeper mines elsewhere. That left a potash gross margin of US$154 a tonne in the quarter, up from US$138, and segment adjusted EBITDA of US$1.24 billion for the half-year, 15 per cent higher than in 2025. In a product that is chemically identical wherever it comes from, the lowest-cost producer earns the margin the price cycle gives it and survives the troughs that break everyone else.

What is Canpotex and why does it matter?

Canpotex is the export marketing agency through which all Saskatchewan potash produced by Nutrien and Mosaic is sold outside Canada and the United States. It was incorporated in 1970, has operated since 1972 and is owned in equal shares by the two producers, with offices in Saskatoon, Singapore, Shanghai and São Paulo. Because it sells more than 13 million tonnes a year, about a third of global capacity, it negotiates annual and semi-annual contracts with the large state buyers in China and India that in practice set the benchmark for the whole seaborne market. Canada’s Competition Act exempts export cartels of this kind, and United States law has tolerated Canpotex since a 2008 antitrust settlement.

The agency owns its logistics. It has commissioned more than 8,000 specialised covered hopper cars, which run on Canadian Pacific Kansas City lines from the mines to the coast, built a C$55 million maintenance yard near Lanigan, and controls terminal capacity at Neptune Terminals in North Vancouver and its own terminal in Portland, Oregon, with smaller flows through Thunder Bay and the Gulf of Mexico. That infrastructure is why Nutrien’s offshore volumes can shift quickly between Brazil, Southeast Asia, China and India as prices move; in the second quarter of 2026 Latin America took 47 per cent of Canpotex volumes, up from 42 per cent a year earlier, as Brazilian soybean growers bought ahead of a larger planting.

For Nutrien the agency functions as a related party as much as a customer. The company booked purchases from Canpotex of US$122 million in the first half of 2026 and had US$339 million of receivables from it at 30 June. Mosaic, the Florida-based phosphate and potash producer whose Saskatchewan mines at Esterhazy and Belle Plaine neighbour Nutrien’s, shares the system but competes with Nutrien in North America. The arrangement is one reason the arrival of a third major Saskatchewan producer that is not a Canpotex member is seen as the most important change to the industry in a generation.

What does BHP’s Jansen mine change?

Jansen will be the first large greenfield potash mine built in Saskatchewan since the 1970s and will belong to a company outside the Canpotex system. BHP, which had been blocked from buying PotashCorp in 2010, sanctioned Jansen Stage 1 in 2021 and Stage 2 in 2023, and describes the total investment as about US$15.3 billion. Stage 1 is designed for 4.15 million tonnes a year once fully ramped up and Stage 2 for a further 4.36 million, giving 8.5 million tonnes combined, with brownfield potential for up to 8 million tonnes more. The site lies about 140 kilometres east of Saskatoon on mineral leases covering some 8,600 square kilometres of the Prairie Evaporite, and BHP expects the mine to operate for more than 60 years.

The project has not been cheap. In its operational review of 18 July 2025 BHP raised the Stage 1 capital estimate to a range of US$7.0 to 7.4 billion including contingency, from the original US$5.7 billion, while confirming first production for the middle of calendar 2027; Stage 2 was approved at US$4.9 billion, or about C$6.4 billion. In July 2026 chief executive Brandon Craig told investors that Jansen remained on track to begin producing potash the following year, adding a new commodity to a portfolio built on iron ore and copper.

For Nutrien the implications are mixed. Jansen’s first stage alone is equivalent to roughly 5 per cent of current global demand and will arrive in a market that was oversupplied as recently as 2024, which will weigh on prices in the early 2030s as Stage 2 ramps up. On the other hand, BHP’s willingness to spend US$15 billion is the strongest possible endorsement of the long-term demand thesis that underpins Nutrien’s own valuation, and much of Jansen’s early output is likely to displace higher-cost supply from Russia, Belarus and elsewhere rather than Canadian tonnes. Nutrien has said it can expand its own mines by several million tonnes at a fraction of Jansen’s capital cost if the market needs it, which is the low-cost incumbent’s classic response to a new entrant.

How exposed is Nutrien to US tariffs and American farmers?

The United States is Nutrien’s largest market in every segment, and American farmers buy more than 80 per cent of their potash from Canada, so the trade war that began in early 2025 was the company’s most important political risk. When Washington imposed tariffs on Canadian goods in March 2025, potash was among the products singled out for a reduced 10 per cent rate rather than 25 per cent, and goods compliant with the Canada-United States-Mexico Agreement were subsequently exempted, which covered the bulk of Nutrien’s cross-border potash and nitrogen. The company has nevertheless listed general and retaliatory tariffs among the explicit risks in every results release since, and the 2026 review of the trade agreement, examined in the article on the CUSMA review, keeps the issue open.

The exposure runs in both directions. Nutrien’s nitrogen plants in Alberta export ammonia and urea to the US Midwest, its phosphate operations are in North Carolina, and its retail network is predominantly American, so a tariff on Canadian fertiliser would raise costs for its own customers and squeeze the retail margin. Conversely, the company’s North American realised potash price of US$295 a tonne in the second quarter of 2026, well above the US$259 offshore price, reflects the logistical advantage of being the nearest supplier to the world’s largest corn and soybean belt. That premium is the asset a tariff would erode.

Farm economics are the other side of the equation. Nutrien’s August 2026 outlook described firmer crop prices and growers focused on protecting yields, forecast strong demand for the autumn application season, and noted that El Niño conditions and geopolitical risk could lift crop prices further. In Brazil, where the company runs a retail business under strategic review, soybean acreage was expected to rise moderately but purchasing depended on credit; in Australia, strong livestock economics supported demand. The broader Canadian context of export diversification away from the United States is covered in the article on Canada’s export diversification.

Why is the retail business so important?

Nutrien Ag Solutions is the largest single contributor to group earnings and the main reason Nutrien’s results are less volatile than those of a pure mining company. The retail segment earned adjusted EBITDA of US$1.13 billion in the second quarter of 2026 and US$1.24 billion for the half-year, against US$1.24 billion from potash, US$1.12 billion from nitrogen and only US$80 million from phosphate, and the company guides to US$1.75 to 1.95 billion of retail EBITDA for the full year. The network of more than 2,000 locations sells seed, crop-protection chemicals, nutrients and agronomic services to farmers in the United States, Canada, Australia and South America.

The strategic value is in proprietary products and data. Nutrien’s own-brand seed, biologicals and crop-nutrition lines earn higher margins than third-party products, and management highlighted strong growth in proprietary-product margins in the 2026 half-year. The retail arm also gives the company a view of planting intentions, application timing and credit conditions that a mine-gate seller never has, which feeds back into how it schedules potash and nitrogen production. Since late 2024 Nutrien has sold about US$1 billion of non-core assets, mostly retail sites and businesses that did not fit, and in 2026 it was concluding strategic reviews of the Brazilian retail operation, the phosphate business and the Trinidad nitrogen plant.

The Trinidad decision shows how the portfolio is being pruned. Nutrien began a controlled shutdown of the Point Lisas ammonia and urea complex on 23 October 2025, citing unreliable and uneconomic natural gas supply and port restrictions, and on 5 October 2026 announced an indefinite shutdown after its review, saying the move would improve free cash flow and return on invested capital and that 2026 guidance already assumed no Trinidad production. Nitrogen volumes are to be grown instead from North American plants through reliability and debottlenecking projects, following what the company described as the largest turnaround in the history of its Carseland facility in Alberta.

How does Nutrien allocate its capital?

Nutrien’s capital policy favours steady returns over expansion. The quarterly dividend was US$0.55 a share in 2026, giving US$1.10 for the half-year, and the company repurchased 4.58 million shares for US$327 million in the first six months at an average price of about US$70, a 26 per cent increase in buybacks over 2025. Total cash returned in the half reached US$848 million. Capital expenditure guidance for 2026 was trimmed to US$1.95 to 2.05 billion, and in May 2026 the company issued US$1 billion of five- and ten-year senior notes to refinance maturing debt rather than to fund growth.

The contrast with the previous cycle is deliberate. In 2022 and 2023 Nutrien announced plans to expand potash capacity towards 18 million tonnes on the back of the war-driven price spike, then paused the programme when prices collapsed; the current management emphasises low-cost brownfield options at existing mines, autonomous mining equipment and reliability over new capacity. Chief executive Ken Seitz has framed the 2026 strategy around operational excellence, targeted growth investment and portfolio optimisation to produce structurally higher free cash flow, and the investor day scheduled for 30 November 2026 is expected to set out multi-year targets on that basis.

The company’s shareholder base reflects its dual character. Index funds and Canadian pension managers hold it as a large-cap dividend payer, agricultural specialists hold it as a play on crop prices, and in June 2026 the board felt obliged to warn investors against a below-market “mini-tender” offer from an opportunistic buyer, a routine hazard for widely held stocks. The investment funds profiled in the article on CPP Investments and the Maple Eight are among its long-standing holders.

What is the outlook for potash prices and Saskatchewan?

Potash demand is growing at roughly 2 to 3 per cent a year as developing-world diets shift towards protein and as farmers in Brazil and Southeast Asia correct historic under-application, and the market in 2026 looks balanced rather than tight. Nutrien’s forecast of 74 to 77 million tonnes of global shipments for the year would be a record, supported by affordable prices relative to crop values and restocking in China and India. The sanctions and logistics constraints on Belarusian supply have eased, Russian exports have found new routes, and new capacity from Jansen in 2027 and projects in Laos and Russia later in the decade will keep the price range below the 2022 extremes.

Saskatchewan’s position within that market is secure because of geology and infrastructure. The province holds the largest known potash reserves in the world, its mines are among the shallowest and highest-grade, and the rail and port system that Canpotex has built over fifty years cannot be replicated quickly. The provincial government collects royalties and a potash production tax that rise and fall with the cycle and that made up a significant share of its resource revenue in the 2022 boom; the arrival of a third major producer broadens that base. The Canadian railways that carry the product, examined in the article on CN and CPKC, treat potash as one of their most reliable bulk franchises.

The risks are on the demand side rather than the supply side. Farm incomes in the United States and Brazil, interest rates and credit availability, and the course of trade policy between Washington, Ottawa and Beijing will do more to set Nutrien’s 2027 earnings than any decision in Saskatoon. The company’s own guidance is appropriately conditional, and its emphasis on cost, reliability and cash returns is a way of making the business robust to outcomes it cannot control.

What can founders and investors learn from Nutrien?

The first lesson is that cost position is the only durable advantage in an undifferentiated product. Nutrien’s potash is identical to Mosaic’s, BHP’s or Uralkali’s, and the price is set by the marginal tonne; what distinguishes the company is a cash cost of US$55 a tonne that lets it earn through the trough and expand into the recovery. Any founder selling a commodity, whether electricity, cloud storage or a generic drug, should know their position on the industry cost curve before they know anything else.

The second is that vertical integration is worth more in volatile industries than in stable ones. The Agrium merger was criticised in 2017 as a conglomerate deal, but the retail network’s US$1.24 billion of half-year earnings in 2026 is what allows Nutrien to maintain a US$0.55 quarterly dividend while potash prices sit at a third of their 2022 peak. The parallel with grocery, where the Weston family’s control of distribution is examined in the article on Loblaw and Weston, is instructive.

The third is that collective export institutions can be a legitimate and powerful strategy. Canpotex has given two Canadian producers pricing discipline, logistics scale and market access for more than fifty years, under legal exemptions that reflect a deliberate national choice. Founders in fragmented export industries should look at whether joint marketing, shared infrastructure or industry-wide standards can achieve what no single company could.

The fourth is about new entrants. BHP’s Jansen is the kind of competitor that cannot be blocked, bought or out-lobbied: a larger company with a longer time horizon building a lower-risk asset in the same geology. Nutrien’s response of disciplined capital, lower cost and a wider moat in retail is the correct one, and investors should expect a decade in which the price of potash is lower and Nutrien’s share of the market is smaller, but its earnings may still be higher because the business around the mine is stronger.
