Environmental needs:

  • Blue (narrow-leafed) lupin prefers fresh, less acidic soils
  • Loamy sand, sandy loam
  • Requires lots of water to trigger germination - only germinates in the right weather conditions
  • Moderately warm climate
  • Roots are able to utilise low soil moisture
  • Sensitive to dry conditions in late summer
  • Dies off at temperatures below -4 to -6 °C

Use:

  • Blue (narrow-leafed) lupin contains bitter substances and is mainly used as green manure
  • Yellow and blue lupins improve soil structure and are considered pioneer plants

 

Green manure:

  • Roots penetrate soil deeply
  • Nitrogen-fixing
  • Plenty of green manure mass that dies off in winter (harvest residue: 16-20 quintals DM/ha)
  • Roots improve soil both biologically and mechanically
  • Roots penetrate compacted soil layers
  • Valuable precrop
  • Very good bee pasture
