New guide for farmers to help reduce air pollution from ammonia

A new guide published today sets out the steps farmers, advisors and contractors can take to reduce ammonia emissions and help improve air quality.

Defra’s Clean Air Strategy highlights that agriculture is responsible for 88% of UK emissions of ammonia gas, which ‘over-fertilises’ natural habitats with nitrogen and combines with other pollutants to produce fine Particulate Matter pollution which is harmful to human health.

The Code of Good Agricultural Practice (COGAP) for Reducing Ammonia Emissions sets out simple steps all farmers can take to reduce ammonia emissions, such as using a nutrient management plan to calculate fertiliser application rates. It also includes more significant changes to slurry storage, spreading equipment and infrastructure, alongside innovative techniques such as slurry and digestate acidification and separation.

Environment Minister Thérèse Coffey said: “Air pollution is not just an urban issue and with 88% of ammonia emissions coming from farming, the government is taking concerted action. With clear new guidance and financial support we will help farmers across the country to take action, reduce emissions and help improve air quality.”

In addition to the new guidance, Defra is providing a package of financial and technical advice to help farmers reduce their emissions.

Defra is investing £3 million over the next three years to fund a specialist team of experts who will offer support, advice and guidance on the most effective ways to reduce emissions from ammonia on their land.

It will also fund demonstrations of the latest low-emission spreading equipment and one-to-one advice on reducing ammonia emissions which will be available from Catchment Sensitive Farming officers by the end of this year.

The RDPE Countryside Productivity scheme is currently offering 40% grants towards much of the manure management equipment recommended in the COGAP to reduce ammonia emissions. This includes low-emission spreading equipment, slurry and digestate storage bags, digestate processing equipment and mild acidification equipment.

Farmers in priority catchments for reducing water pollution may also be eligible for grants towards covers for slurry stores and lagoons under the Countryside Stewardship scheme.
