Notes:
  • Low bloat potential
  • Inoculate with Rhizobia bacteria specific to sweetclovers (Type A).
  • Moldy hay can cause coumarin toxicity.
  • Coumarin is an aromatic bitter taste compound. Mold converts coumarin to dicoumarol an anticoagulant.
  • Low-coumarin cultivars are being developed and tested (2006).
