Rising fertiliser costs rarely make headlines in the way oil prices or interest rates do, yet they sit at the very foundation of the global food system. In 2026, this largely invisible input has become one of the most important economic pressure points facing farmers in the United Kingdom and around the world—and its effects are beginning to ripple outward toward consumers.
At the heart of the issue lies energy. Modern fertiliser production, particularly nitrogen-based products, depends heavily on natural gas. When gas prices surge—as they have amid ongoing geopolitical tensions and supply disruptions. The cost of fertiliser rises almost in lockstep. For farmers, this creates an immediate and unavoidable dilemma: absorb sharply higher input costs or reduce usage and risk lower yields at harvest.
This is not simply a theoretical concern. Across multiple regions, farmers are already cutting back. Some are applying less fertiliser than agronomic recommendations suggest; others are forgoing it altogether. While this may preserve cash flow in the short term, it carries a predictable consequence. Lower fertiliser use typically leads to weaker crop growth and reduced output, particularly for staple grains such as wheat, maize, and rice. The result is a delayed but powerful shock to food supply.
In the United Kingdom, the situation is especially acute. British farmers are highly exposed to global markets for fertiliser and energy, importing a significant share of what they use. Domestic production has struggled under high energy costs, leaving the sector vulnerable to international price swings.
At the same time, farmers are contending with elevated fuel prices, labour pressures, and broader post-Brexit adjustments. The cumulative effect is a tightening squeeze on margins that leaves little room for manoeuvre.
Globally, the picture is even more complex. Fertiliser supply chains are being strained not only by rising costs but also by physical disruptions. Key production and export routes have been affected by conflict and instability, while some manufacturers have reduced or halted output altogether. In this environment, access to fertiliser is becoming as much a question of availability as affordability.
This dynamic is particularly troubling because of the time lag built into agriculture. Unlike many industries, farming cannot quickly adjust to shocks. Decisions made at planting deciding how much fertiliser to apply, which crops to grow and determine outcomes months later. By the time reduced yields become visible, the opportunity to correct course has long passed. In other words, the pressures being felt today are likely to shape harvests well into 2027.
For consumers, the implications are increasingly clear. Food prices are already under upward pressure, and fertiliser costs are likely to amplify that trend. Analysts expect further increases over the coming year, with staple foods particularly affected. Grain prices influence not only bread and cereals but also meat and dairy, as animal feed becomes more expensive. This creates a cascading effect throughout the food chain, making inflation both broader and more persistent.
In wealthier countries such as the UK, this is likely to manifest as a cost-of-living challenge rather than a supply crisis. Supermarkets will remain stocked, but households especially those on lower incomes—will feel the strain of higher bills. Governments may face renewed pressure to intervene, whether through subsidies, support schemes, or trade measures aimed at stabilising supply.
The risks are far more severe in lower-income regions. Many developing countries depend heavily on imported fertiliser and lack the financial capacity to absorb price shocks.
As costs rise, farmers in these regions are often forced to cut usage dramatically, leading to significant declines in crop yields. Combined with existing vulnerabilities such as climate change, political instability, and limited infrastructure. This creates the conditions for acute food insecurity.
Warnings from international organisations and industry leaders suggest that, if current trends persist, parts of the world could face serious shortages. While the term “famine” should be used with caution, the underlying risk is real. Reduced agricultural output, rising prices, and diminished access to food for the most vulnerable populations. In such scenarios, the effects are not evenly distributed as they fall disproportionately on those least able to cope.
What happens next will depend largely on how long current pressures endure. A stabilisation in energy markets or an easing of geopolitical tensions could bring fertiliser prices down and limit the damage. However, if disruptions continue into next year, the world may be facing a prolonged period of elevated food prices and heightened food security risks.
The story of fertiliser is a reminder that the global economy is deeply interconnected in ways that are not always visible. A spike in natural gas prices can affect a fertiliser plant that, in turn, influences a farmer’s decisions; and those decisions ultimately shape the price of food on supermarket shelves thousands of miles away. In 2026, this chain of cause and effect is becoming impossible to ignore.
For policymakers, farmers, and consumers alike, the message is the same: what happens beneath the surface of agricultural production can have profound consequences above it. The coming year will reveal just how resilient—or fragile—that system truly is.
