Excellent at nitrogen fixing, legumes produce a nitrogen rich dry matter yield which quickly breaks down once incorporated offering benefits to your planned crop rotations. Also used to prevent or reduce soil erosion and encourage beneficial insects for future crops. We welcome enquiries for bespoke mixtures and have expert staff on hand to offer advice. Feel free to call 01205 280069 or email info@bostonseeds.co.uk

Berseem Clover Seed (Trifolium alexandrinum)

Berseem clover is an annual, nitrogen fixing legume which is noted for its rapid establishment. Popular for autumn sowing works well as a winterkilled cover.

  • Popular for early autumn sowing, to fix nitrogen before it is killed by winter frost
  • Compatible in seed mixtures with grass and legumes
  • Nitrogen fixing legume with rapid growth and establishment
  • Sow from spring to early autumn. Not frost tolerant
  • Sowing rate: 15kg/ha.

Black Medick (Yellow Trefoil) Seed (Medicago lupulina)

A low growing green cover crop which fixes nitrogen and suppresses weeds. Often sown amongst brassica crops.

  • A biennial/annual legume that gives good yields even on thin calcareous soils
  • Few legumes outperform medic in soil-saving and soil-building
  • May be grazed by sheep, main use is as a green manure undersown in cereals
  • Low growth habit makes it useful in vegetable intercropping systems
  • Sowing rate: 12kg / ha

Blue Lupin (Lupinus augustifolious)

Lupin is a highly efficient nitrogen fixer with a very aggressive taproot which grows deep into the soil and retrieves nutrients usually unavailable to other species. 

  • Deep taproot breaks soil compaction and retrieves nutrients 
  • Well adapted for acid soils but grows in soils up to pH 8
  • Highly efficient at fixing nitrogen and extracting phosphorus from the soil 
  • Can be cut for hay and high quality silage
  • Sowing rate: 25kg per acre

Crimson Clover Seed (Trifolium incarnatum)

Crimson clover is a brightly coloured legume which attracts a large numbers of insects. Tolerant of poor soils provided they are alkaline and free draining. 

  • Excellent weed suppressor, fast establishing and good nitrogen fixer
  • Lower yields of biomass than Red Clover but has much shorter growing period
  • Biomass degrades very quickly in the soil releasing nutrients for future crops
  • Will over-winter in Southern England for autumn sowing and spring incorporation
  • Sowing rate: 15kg / ha

Lucerne Seed (Medicago sativa)

Lucerne is a longer term perennial clover which fixes large amounts of nitrogen from the air to enrich the soil.

  • A longer term perennial clover which fixes large quantities of nitrogen
  • Widely used for green manure
  • Large tap root which is ideally suited to light and chalky soils as well as dry climates.
  • Seed is supplied inoculated with rhizobium bacteria
  • Sowing rate: 25kg / ha

Persian Clover Seed (Trifolium resupinatum)

Persian clover is an is an annual, nitrogen fixing legume which is widely used across Europe and is useful as a forage plant.

  • Spring sown for grazing and cutting or autumn sown, for rapid spring growth
  • An efficient nitrogen fixing legume to assist future crops
  • Suitable for use with poorer soils and drought conditions
  • Compatible in seed mixtures with grass and legumes
  • Sowing rate: 7-10kg / ha

Red Clover Seed (Trifolium pratense)

Red clover is an aggressive, nitrogen fixing plant which is an effective weed suppressor. Good for improving and aerating soil structure.

  • A shorter term alternative to White Clover, will usually last for two years 
  • An aggressive plant, providing a large mass of green vegetation
  • Fixes large amounts of atmospheric nitrogen which is released once ploughed in
  • Large tap root which penetrates deep into the ground, improving soil structure
  • Sowing rate: 15kg / ha

Sainfoin (Agricultural) (Onobrychis)

Sainfoin is ideal as a long term cover crop in free draining soils, with strong drought resistance and tolerance of low nitrogen soils.

  • A nitrogen fixing perennial legume with good drought tolerance
  • Excellent high protein forage for horses being very palatable 
  • Copes well with poor nutrient soils and drought conditions
  • Sainfoin leys can be considered to last four years or more
  • Sowing rate: 65-100kg / ha

White Clover Seed (Trifolium repens)

White clover is widely used throughout the UK. It is an important element of many silage and grazing mixtures, thanks to its persistence and nitrogen fixing properties.

  • A longer term and more persistent option than Red Clover
  • Very palatable for livestock and high in protein 
  • Continued defoliation stimulates root growth and nitrogen fixation
  • Prefers to be shallow sown into a fine, firm seed bed
  • Sowing rate: 5-10kg / ha

Yellow Blossom Clover (Sweet Clover)

Yellow Blossom Clover is a biennial plant that can persist for several years due to its self regenerating properties. 

  • A deep rooted legume that improves soil structure and fertility
  • Nectar rich specie which attracts pollinators to aid future crops
  • Often sown with Kale to help provide cover in the first year
  • Stems become woody in second year to help with standing
  • Sowing rate: 5kg / ha
