Farmers are facing further restrictions on both organic and inorganic fertiliser including manures, slurries and nitrogen rich chemicals.  

These new controls will be extended to large dairy farms by 2025 which is similar to the permits already in place for intensive pig and poultry units.  

The proposals are set out in the government's Clean Air Strategy which was launched by Defra secretary Michael Gove on Tuesday.  

The government are taking action to tackle ammonia from farming which the document reports is responsible for 88% of ammonia emissions.

Farmers are going to be required to invest in infrastructure and equipment necessary to reduce the emissions and will be supported to do so through a new system of public money for public goods.   CLA president Tim Breitmeyer has commented that any system must provide flexibility and easy engagement for farmers.
