Fertility building leys field lab

16 September 2014

Fertility building leys and green manures: Field lab 3 at Abbey Home Farm, Burford Rd, Cirencester, GL7 5HF

This Duchy Originals Future Farming Programme field lab, facilitated by ORC's Mark Measures focuses on:

  • Increased forage yield
  • Improved nitrogen fixation and release to following arable crops
  • Resilience to variable environmental conditions
  • Benefit for bees and other pollinators

Meeting 3 - 16 September: At the final meeting at Abbey Home Farm, we will review farm experiences to date. We will also review plans and ideas for further research. This will also include a tour of ORC's OSCAR plots with some training provided on assessments.

The ORC Leg LINK research project shows the potential for a major change in forage seed mixtures towards more diverse swards including specific legume species. Informed by research from IGER North Wyke and recent field research on crop yields at Reading University this series of three Field Labs will help you select mixtures for your farm:

  • Characteristics and selection of legume species including red and white clover, lucerne, black medic, trefoil, crimson clover and sainfoin
  • The importance of including grass species
  • Use of diverse mixtures for fertility building in arable rotations
  • Prepare for new Defra support for diverse mixtures in 2016
