Opt for ryegrasses to aid grass growth
Perennial varieties 'will greatly increase profits'
Old, unproductive grass swards are costing Irish farmers €200-300/ha every year compared to reseeded pastures.
Speaking at a Germinal Seeds reseeding conference, Teagasc grassland expert Michael O'Donovan warned that farmers are also suffering further losses by not reseeding because of the improved response to nitrogen that reseeded paddocks show when compared to old swards.
Teagasc research has highlighted massive variations in grass production, both between farms and within farms.
There is a 40pc difference in grass production between the most productive grassland farms and the least productive units in the country.
However, there are also stark differences in grass production levels even within farms.
Analysis has shown that there can be as much as a 60pc difference between the amount of grass grown on one part of a farm to another part of the same holding.
While there are numerous reasons behind this difference, including poor soil fertility, soil type, drainage issues and poor management, the most obvious is the lack of perennial ryegrass within pastures.
