Agriculture: Fertilisers
The question
To ask the Secretary of State for Environment, Food and Rural Affairs, what assessment she has made of the potential contribution of domestically produced polyhalite fertiliser to improving the resilience and security of fertiliser supplies for UK agriculture.
Answered by Stephen Morgan
Polyhalite satisfies a proportion of the UK’s sulphur demand, but it is not a direct substitute for nitrogen or phosphate-based fertilisers. It can, however, be blended with other fertilisers to increase nutrient use efficiency and provide a balanced nutrition for plants.
The UK sources fertiliser both domestically and through diverse imports, helping keep supply chains flexible and maintain a diverse nutrient supply.
