Nitrogen fertiliser is getting expensive again, and the knock-on is landing squarely on the desks of the UK’s agricultural merchants and the farmers who buy from them. After a relatively calm patch, prices have been climbing through 2026, and the trade body representing the supply industry is now pressing the government for help.
The Agricultural Industries Confederation (AIC) called on Defra in April 2026 for clarity on the fertiliser market, including credit support for farmers whose cashflow is already stretched. That request followed figures from the Andersons Centre putting UK agricultural input inflation at an annualised 7.6% in March 2026 – the fastest pace since the start of the Russia-Ukraine war in 2022 – with UK farmgate nitrogen trading at around £500 a tonne where supplies were available.
What’s driving the rise
The root cause is gas. Nitrogen fertiliser production is energy-intensive, and the Middle East conflict has kept gas prices elevated through the year, feeding straight through to manufacturing costs. AHDB has tracked the effect directly, reporting price rises of between 13% and 36% across a range of fertiliser products since February 2026, and has published weekly fertiliser price updates since 27 March to help farmers and merchants see where the market is heading.
The trend hasn’t let up heading into autumn. By September, granular urea was trading at around £470 a tonne delivered, and merchants were again urging customers to place orders early rather than wait and risk paying more – or finding supply tight – once demand picks up ahead of spring applications.
Why it matters beyond the fertiliser aisle
AHDB expects fertiliser to be the single biggest driver of higher crop production costs for harvest 2026, pushing the full economic cost of growing winter wheat up by roughly 3% to about £1,659 a hectare. That squeeze arrives on top of already-tight margins, and it changes the conversation farmers are having with their local merchant: less about which product to buy, and more about when to buy it and how to spread the cost.
For a lot of farms, ordering early – locking in a price before the next seasonal jump – has gone from a nice-to-have to a genuine budgeting strategy. It’s also why access to credit has become part of the same conversation; the AIC’s call for Defra support was specifically about helping farmers manage purchases through a cashflow-constrained season, not just the headline price.
Where this leaves farmers and merchants
None of this is unique to one region. Whether a farm is buying from a merchant in Borehamwood, Royston or Stornoway, the same forces are at play: a tighter global gas market, a knock-on rise in nitrogen costs, and a supply chain trying to plan several months ahead in a market that keeps moving. Local agricultural merchants are generally well placed to talk through timing and alternatives with regular customers, and that relationship matters more in a year like this than in a calmer one.
The practical takeaway for anyone budgeting for the coming season: treat fertiliser like a cost worth watching weekly, not an afterthought to sort out closer to application time.
