Current reseeding rates of 2-3% per year are far from the required rate if livestock farms are to maximise returns from forage. Grass leys are replaced far less often than every 10 years. Even the best managed swards will suffer deterioration beyond 6 - 7 years with the ingress of weed grasses inevitable though not always obvious.
These all add up to make successful pasture renewal one of the most cost effective investments.
Whether used for extra milk production or additional weight gain, the extra productivity per acre of a new grass ley is significant running into hundreds of pounds over and above the reseeding costs. The benefits of the first year should then continue for the duration of the ley.
Utilising grass-seed mixtures, which include the top varieties on the Grass and Clover Recommended List (RGCL) from leading plant breeding programmes, guarantees higher yielding and better quality leys that can offer more efficient fertiliser use and boost both grassland productivity and animal output. So say...
