Field Options & Anaerobic Digesters

Field Options is a specialist business which has been supplying seed and associated products to ruminant livestock businesses throughout England and Wales for 10 years. The business focusses on helping farmers optimise forage crop production and utilisation. This includes guidance on soil management, sustainable rotation planning, utilisation of manures and the growing, storing and ensiling of forages relevant to the nutrient requirements.

We have written a short document to outline some basic strategies, and how we can help with the running of AD plants.  This covers crop selection, ensiling and digestate utilisation.

Technical Data

What are the objectives of feedstock selection?

  • Maximum digestible carbohydrate yield.  Only carbon and hydrogen are required - protein levels (= nitrogen) should be as low as possible.
  • Sustainable crop rotation maximising opportunities to apply digestate.
  • Only crops fully adapted to soils, climate, growing skills, storage and machinery available. 
  • Spread of harvesting and planting dates to manage risk.
