Fertilizer Costs Are Rising Again — And Prairie Margins Can’t Absorb It Easily

Western Farm Report | April 2026

Fertilizer prices are climbing again heading into spring 2026, and the combination of higher input costs and softening commodity prices is squeezing grain and oilseed margins across the Prairies. Urea prices have surged more than 48% above year-ago levels in North American benchmark markets as of mid-April. Anhydrous ammonia is running about 40% higher year-over-year. DAP and MAP, the dominant phosphate sources in Prairie cropping systems, are also elevated. The cost structure producers locked in over the past two seasons no longer reflects where the market is today.

This is not a repeat of the 2022 spike, when urea briefly surpassed USD $1,000 per tonne. But it is a meaningful re-escalation from the trough of 2023-2024, when declining natural gas prices and improved global supply pushed fertilizer costs lower. That temporary relief has ended. Producers planning 2026 inputs need to understand what is driving the current move, where Prairie-specific risks sit, and what agronomic levers are available to protect margins without sacrificing yield.

What Is Driving the Price Increase

Natural gas is the primary feedstock for nitrogen fertilizer production. Nitrogen-based products — urea, anhydrous ammonia, and UAN — account for the largest share of Prairie fertilizer expenditure by value, and all three are tightly linked to energy markets. In 2025, natural gas prices rose from their multi-year lows. U.S. forecasts put the average Henry Hub price for 2026 at roughly $4 per million BTU, approximately 16% above the 2025 average. That input cost increase works its way directly into urea and ammonia manufacturing margins.

Geopolitical disruption compounded the energy story. Earlier in 2025, tensions in the Middle East, particularly involving Iran, raised concerns about ammonia and urea supply moving through the Persian Gulf and Suez Canal. That risk premium added to price volatility even before physical supply was interrupted. By spring 2026, with U.S. military action blocking traffic through the Strait of Hormuz, supply disruption risk has become material. Western Canada’s domestic nitrogen production capacity provides a buffer relative to Eastern Canada, but Prairie markets are not insulated from global price signals.

On the phosphate side, China’s decisions about export volumes have had outsized influence. Early in 2025, China restricted phosphate and urea exports to protect domestic supply. That drove DAP prices from approximately USD $583 per tonne in January 2025 to nearly $800 by mid-year — a 36% increase in under eight months. China partially reopened exports in summer 2025, providing brief relief, but the policy uncertainty remains. Any renewed restriction could push phosphate costs higher again before the 2027 seeding season.

Saskatchewan potash, a Canadian export product, is in comparatively better shape. Potash prices have risen modestly — roughly 5% year-over-year — but remain near their pre-2020 baseline. Canada’s position as the world’s dominant potash producer and exporter provides supply stability that nitrogen and phosphate markets do not enjoy. The main risk for Prairie potash users is not supply shortage but the indirect effect of U.S. tariff policy, which could disrupt the southbound trade flows that underpin Canadian mine economics.

Prairie Price Benchmarks

Alberta Agriculture and Irrigation farm input price data through May 2025 — the most recent published survey — showed bulk urea (46-0-0) at approximately $894 per tonne, up from roughly $808 per tonne a year earlier. MAP (11-51-0) was tracking around $1,262 per tonne, and anhydrous ammonia (82-0-0) with full-service application was recorded near $1,353 per tonne.

U.S. benchmark data through mid-April 2026 shows urea averaging USD $847 per tonne and anhydrous ammonia at USD $1,088 per tonne — up 48% and 40% respectively from a year ago. Cross-border price relationships are not one-to-one given currency effects, domestic production volumes, and freight differentials, but the direction of movement is consistent. Saskatchewan and Manitoba price points tend to track similar trajectories, adjusted for local logistics and supply contracts.

Statistics Canada’s 2024 farm income data, published in May 2025, showed national fertilizer expenses of $9.1 billion — down 7.2% from 2023 as that year’s price correction worked through the system. The 2026 crop year is unlikely to sustain that reprieve. Agriculture and Agri-Food Canada forecasts net farm income declining roughly 15% in 2025 from 2023 levels, and the combination of elevated fertilizer costs against soft grain prices in 2026 keeps the margin picture unfavourable.

The Nitrogen Rate Question on the Prairies

Elevated nitrogen costs make rate management more consequential than it has been in several years. Research from the AAFC Swift Current Research and Development Centre has identified systematic differences between recommended nitrogen rates and actual producer application rates in Western Canada. Prairie nitrogen use has more than doubled since 1990, reaching approximately 2.9 million tonnes by 2021, and the gap between official recommendations and field application rates has widened for canola, spring wheat, and durum.

Canola nitrogen requirements vary considerably by soil zone. AAFC field research from multiple site-years found the economic optimum nitrogen rate for canola in Black soil zones at 146 to 166 kg N/ha, dropping to 85 to 100 kg N/ha in the lighter Brown soil zone, with the Brown-Black junction zone around 120 kg N/ha. Under favorable conditions with high soil organic matter, EONR can reach 200 kg N/ha on Black Chernozem soils to hit a 52 bu/ac target.

Agronomists in Saskatchewan have noted that some canola operations are applying 140 to 160 pounds of nitrogen per acre to produce 50 bu/ac crops — rates that exceed the economic optimum, particularly at current input prices. At USD $847/tonne urea, the cost of excess nitrogen applied above the EONR becomes a direct hit to net return. The formula shifts when canola prices are compressed and nitrogen prices are elevated: applying fertility at the upper end of the rate range makes less economic sense than it did when canola was trading $200/tonne higher.

For Canada Western Red Spring wheat, AAFC trials across Alberta and Saskatchewan sites from 2019 to 2022 evaluated N rates from 60 to 240 kg N/ha across five nitrogen sources. The research found that N source effects on grain yield were site-specific, with Dark Brown Chernozem soils responding to source differences in ways that Black Chernozem and Dark Grey Luvisol soils did not. The practical implication is that blanket N rate assumptions across zone types carry both agronomic and economic risk.

Enhanced Efficiency Fertilizers and Federal Programming

Enhanced efficiency fertilizers (EEFs) — including urease inhibitors, nitrification inhibitors, and polymer-coated slow-release products — represent one pathway to maintaining yield while reducing total N applied. AAFC research on winter wheat across Prairie sites showed that NBPT-treated urea improved nitrogen use efficiency on sandy loam soils, though benefits were not consistent on clay loam soils. Polymer-coated products (ESN) and dual-inhibitor formulations showed yield and protein benefits at certain sites and N rates.

EEF adoption rates on the Prairies jumped significantly in 2024, according to the 2024 Fertilizer Use Survey. Feed barley saw EEF use rise from under 10% of acres to 46% in a single year. Most other crops saw 3 to 8 percentage point increases. The driver is federal funding: Agriculture and Agri-Food Canada’s On-Farm Climate Action Fund (OFCAF) allocates $300 million from 2025 to 2028 for cover crops, rotational grazing, and nutrient management practices including EEF adoption. Producers who adopt qualifying practices can access payments that offset the cost premium EEFs carry over standard urea.

The OFCAF nitrogen management funding is available nationally through delivery organizations. Producers who have not yet accessed this funding and who are considering EEFs for 2026 should contact their provincial delivery organization or check with AAFC directly. At current nitrogen prices, the economics of EEFs are more competitive than they were in 2023-2024 — reducing volatilization and denitrification losses carries greater value when each kilogram of N is costing more.

Soil Testing and the 4R Framework

Saskatchewan extended its Memorandum of Cooperation on 4R Nutrient Stewardship with the federal government through 2028 in March 2025. The 4R framework — Right Source, Right Rate, Right Time, Right Place — has meaningful economic relevance at current input prices. A 2024 survey of 1,258 Prairie and Ontario farmers found that fewer than 13 million acres met full 4R compliance in 2024, well short of earlier targets. For canola specifically, only 34% of acres met the Right Rate criteria — meaning producers followed all steps necessary to determine the rate, including current soil testing, yield targets, and agronomic calculation.

Soil testing sits at the foundation of the Right Rate determination. Fewer than 20% of Prairie farmers routinely test soil. At 2022-era fertilizer prices, over-applying nitrogen carried a financial penalty but was partially offset by high commodity prices. At 2026 prices — with canola under pressure from the China trade dispute and wheat prices compressed by global supply — that calculus has changed. The cost of a soil test is recoverable in the first field it prevents from being over-fertilized.

Manitoba’s revised nitrogen guidelines for wheat, barley, and canola account for residual soil nitrogen from previous crops, organic matter contributions, and regional precipitation patterns. Pulse rotations — field pea, lentil, chickpea, faba bean — contribute documented nitrogen credits to subsequent wheat crops. AAFC cropping systems research from Scott and Swift Current, Saskatchewan, found that wheat following pea produced measurably higher protein yield per hectare than wheat following canola in dry conditions, indicating the agronomic value of the nitrogen credit even in stress years.

The Cost-to-Revenue Ratio Is Deteriorating

The relationship between fertilizer cost and expected crop revenue is the central financial metric for input planning. That ratio is moving in the wrong direction in 2026. Canola prices are under downward pressure from China’s trade barriers on Canadian canola and peas. The Canada-China dispute has not been resolved as of this writing, and the continued absence of Chinese buying is preventing any sustained price rally in the oilseed complex. Spring wheat markets face supply pressure from global production recovery since the 2022 post-Ukraine spike.

AAFC’s farm income forecast, published in December 2024, projected a 15% decline in national net farm income in 2025 from already-reduced 2023 levels. The 2026 outlook carries additional risk from the fertilizer cost re-escalation that accelerated through the first quarter of 2026. Prairie crop receipts — particularly in Saskatchewan and Alberta — saw the largest national declines in 2024, and the input cost environment for 2026 provides no relief on the expense side.

The fertilizer-to-crop-price ratio is now at levels that historically prompt producers to pull back on application rates. That response can be rational in the short term. It becomes a risk if it crosses into chronic under-feeding of high-yield genetics that require adequate nutrition to express their potential. The economics of cutting rates deserve careful agronomic scrutiny — the question is not simply whether to apply less, but where in the rate range the decision sits and whether the field’s yield potential justifies the investment.

Western Canada’s Supply Position

Western Canada has structural advantages relative to the rest of the country when it comes to nitrogen supply. Saskatchewan and Alberta host domestic nitrogen fertilizer manufacturing capacity that insulates Prairie markets from the most acute import-dependent price spikes. Eastern Canada, particularly Ontario, sources a significant share of UAN imports from offshore, and those supply chains are more exposed to geopolitical disruption at ocean terminals and through the Hormuz corridor. Western Canada’s issue is not supply security of the same magnitude — it is the direction of benchmark prices, which the domestic market cannot fully escape.

For potash, Canada’s position as the world’s largest producer and exporter provides producers direct access to domestic supply at transportation-adjusted prices rather than the landed import cost that U.S. farmers face. The risk for Prairie potash users is less about physical availability than about whether domestic production economics shift under trade pressure. Saskatchewan potash royalties and mining economics are tied to export prices, not just domestic demand, so global price movements still matter to what producers pay at the retail level.

Planning Considerations for 2026

The central task right now is ensuring that every dollar of fertilizer expenditure is tied to a credible yield target supported by current soil test data. Rates derived from multi-year averages without accounting for residual nitrogen from 2025 — which was, in many Prairie areas, a reasonably productive season — may be over-estimating what new fertilizer needs to supply. In fields with significant residual from the previous year, even a modest test credit against applied nitrogen saves real money at current prices.

Pre-booking decisions require some market judgment about whether April prices represent a ceiling, a floor, or a midpoint. Given the active disruption in Hormuz shipping lanes and the continued volatility in urea export volumes from China, there is no compelling argument that nitrogen prices are about to fall sharply in the near term. Producers who can lock in at current prices with suppliers willing to hold inventory should weigh that option against the risk of waiting for a correction that may not materialize before seeding.

Agronomic flexibility does exist. AAFC cropping systems research from Saskatchewan sites confirmed that crop rotation with pulses provides measurable nitrogen contributions to subsequent cereal crops, reducing the amount of fertilizer N required to hit target yields. In fields where rotational sequencing permits it, a wheat-after-pea placement reduces both the N application requirement and the financial exposure to nitrogen price volatility. That agronomic credit becomes more valuable as the cost of applied nitrogen rises.

Split application strategies — applying a portion of the nitrogen budget at seeding with the balance in-crop — can reduce volatilization risk under warm, wet conditions that characterize some Prairie springs. Research on enhanced efficiency products showed that split-applied N with NBPT-treated urea performed well on winter wheat across multiple Prairie sites and years. The added cost of the inhibitor treatment is more easily justified when the base product price is elevated and every unit of recovery counts.
