How do you spread digestate?
We would be grateful if you could complete the important survey on digestate spreading below by 22/06/2018. It is only four questions and should only take a minute or two!
As you may have seen from our recent communication about DefraÂs draft Clean Air Strategy, Defra has strong concerns regarding ammonia emissions from agriculture and are planning to introduce new requirements to minimise them. To hear more about this issue and other topics related to soil health, donÂt miss the opportunity to come to our Saving our Soils event on 20th June.
According to DefraÂs data inventory, agriculture is the main source of ammonia, accounting for 88% of UK emissions in 2016 (storage, spreading and deposition of manures / slurries and application of inorganic fertilisers).
Ammonia emissions released during storage and spreading of digestate account for 3% of UK ammonia emissions, but this is set to increase as the AD sector grows.
For this reason Defra are considering options for ensuring that, in future, digestate produced through AD incentivised by government is required to be spread using best practice techniques (ie low-emission spreading equipment like trailing shoe or trailing hose or injection.
However, we understand that Defra's assumption is that the most predominant method of spreading digestate is through the use of a splash plate, which produces the highest volatilised ammonia emissions. The REA is keen to evaluate what volumes of digestate are spread and by which technique this is done, so that we can use this information to inform our response to Defra in response to the Clean Air Strategy consultation. All information that you provide will be anonymised and treated in the strictest confidence.Thank you for your participation in this survey, it will assist us in our discussions with DEFRA in the near future.
