Annual medic pastures at MAC locations
Aims

To assess the role of annual medics as a break crop in a wheat-sheep mixed farming system, by measuring the biomass produced over the growing season followed by the retention of the pasture residue over the summer autumn period, then subsequently assessing the impact of the pasture in the following cereal phase in terms of yield and grain quality.

Key messages
  • A regenerated medic pasture in conjunction with a sown forage crop provided the production to sustain a 1000 DSE flock on 200 hectares in 2009.
