    Cereals for Biogas Production

WCS cereals have a firm place in biogas production

Silage maize is still the basic substrate for biogas production. But the surface area of ​cereals for this purpose is increasing and becoming established. According to Basic Data on Bioenergy in Germany 2016, cereal in the form of grains and whole-plant silage accounts for 9% of the renewable raw materials for biogas production.

The growing of cereals-GPS has advantages mainly on soils that are not necessarily suitable for growing maize. These could be heavy, cold soils as well as regions with low spring temperatures, Here, cereals can better take advantage of their yield potential compared with maize.

Reasons for the use of cereals in biogas production

  • Implementation of greening guidelines by expanding crop rotation
  • Winter revegetation
  • Expansion of the recovery window for fermentation residues
  • Breaking down work peaks in silage maize production
  • Utilisation of technology, storage space and know-how
  • Relief in cases of substrate shortages
  • Sufficient time for optimal soil preparation for winter rape or rotation crop
  • Active control of blackgrass due to dense plantings and early harvest

Hybrid rye is especially preferable due to its unexacting habitat demands and low production costs in combination with a high yield potential.
