Compost and anaerobic digestate (also known as AD) are renewable fertilisers providing sustainable crop nutrients and organic matter. If you are a farmer or grower, using these can help increase harvests (how much you produce), maintain fertile soils, and manage your fertiliser bills.
What help can you offer me or my organisation?
We work closely with specialist research organisations and industry representative bodies to make sure our guidance is practical and supported by robust scientific evidence. This programme of work in Wales is funded by Welsh Government.
As well as our downloadable guidance and resources, we can also put you in touch with organisations that can help you further.
How can I access this guidance and information?
If you are a farmer, you may find the following guidance useful:
- Using digestate as a renewable biofertiliser – video providing practical advice for farmers and agronomists on how to maximise the supply of nutrients to crops, and how this can be balanced with standard fertilisers
- DC-Agri project – latest information from this four-year research project looking at the use of quality anaerobic digestate and compost in agriculture, integrated with an extensive knowledge exchange programme
- Using quality compost to benefit crops – guidance document
- Using quality anaerobic digestate to benefit crops – guidance document
- Compost and anaerobic digestate quality for welsh agriculture – final report
- Digestates: Realising the fertiliser benefits for crops and grassland – guidance document
- Biofertiliser management: best practice for agronomic benefit & odour control – final report
If you are a grower, you may find the guidance on WRAP’s ‘Growers’ web page useful.
