Teagasc Drystock Advisor, Hugh Mahon gives analysis about the key benefits of reseeding swards and why it is important.
- Increase productivity - The range of increase is between 15 – 25% which is the equivalent of an extra 3 tonne of dry matter per hectare. This will help to improve the grass sward and stocking rates. There are seven new varieties of grass that feature early spring growth and good back-end growth feature. A good quality, leafy sward will also be produced.
- Increases grazing days - with the feature of early-back-end growth the objective is to extend grazing season as long as possible to make the most of the cheapest feed available – grass.
- Better Nitrogen response in new swards – There is a greater yield in new swards – 5kgs of dry matter production per unit of Nitrogen applied compared to old swards.
- Eliminated old non-productive swards – On a completely re-seeded sward, there should be no competition from weeds.
“Research work carried out at Teagasc have shown a difference of €300/ha extra benefit in comparison with old swards” concluded Mr Mahon.
