Air is a conduit for gaseous pollutants which include odour, ammonia, greenhouse gases and bio-aerosols (dust and particulates). There is an AHDB Pork model template (no. 12) to help produce an odour management plan available here.

Code of Good Agricultural Practice

 The ‘Code of Good Agricultural Practice (COGAP) for farmers, growers and land managers, Protecting our Water, Soil and Air’, published by Defra provides a comprehensive overview of key issues and concise guidance.

The Code describes key actions that can be taken to protect and enhance the quality of water, soil and air. In some cases this may also achieve cost savings for the business. It will also help meet legal obligations including those relating to cross-compliance.
