Farmers are being urged to step up security for fertilizer as spring shipments increase, with warnings that inadequate storage could put businesses at risk of theft and misuse.
New guidance has been published calling on farmers and producers to rethink how they source, store and monitor fertilizers at a time when large quantities of granular products arrive on farms.
The advice comes from the National Counter-Terrorism Security Office (NaCTSO), which says seasonal increases in fertilizer movements could increase risk if basic safety measures are not taken.
Superintendent Steve Fosher, director of NaCTSO, said vigilance is essential regardless of size.
“Regardless of the amount of fertilizer you store, it is important to consider measures to prevent it from being stolen or misused by potential terrorists,” he said, noting that the UK’s threat level remained “substantial and there is a potential for attack”.
NaCTSO, in collaboration with partners such as Red Tractor and Fertilizer Industry Assurance Scheme (FIAS), has developed a five-point fertilizer security plan for farmers and producers using nitrogen-based fertilizers.
The plan focuses on using FIAS-certified suppliers wherever possible, storing fertilizers safely out of public view, conducting regular stock checks, avoiding leaving fertilizers in the field overnight, and ensuring that ammonium nitrate is only sold with the correct documentation.
NaCTSO said the risk is often highest during peak delivery seasons, when fertilizer may be temporarily stored in gardens, sheds or outdoor buildings before being spread.
While no system can provide perfect security, the guidance emphasizes that simple, low-cost steps can significantly reduce the likelihood of theft.
Measures such as storing manure in an enclosed building or covering it with a tarp if stored in an open barn are described as basic but effective.
Further practical advice is available on the Protect UK website. This website provides guidance that can be adapted to individual farm layouts and operations.
The advice recommends a balanced approach that combines physical security with clear procedures and regular checks as part of daily farm management.
Superintendent Foscher said: “It is hoped that following this advice will not only prevent theft that causes financial loss to farmers and producers, but also ultimately limit access to nitrate-based fertilizers used by terrorist groups within the UK.”
He said farmers and producers had an important role to play in reporting concerns. “We all have a role to play in preventing terrorism,” he said. “If in doubt, please report it.”
Farmers are encouraged to remain vigilant when handling and storing fertilizer and to report any unusual incidents to local police, the counter-terrorism hotline on 0800 789 321 or the Protect UK reporting service.
