As grass varieties constantly improve, did you know that by using new varieties could give you 33% more yield than a typical five year ley. The DM yield of the ley will also be much higher.
By selecting varieties from the recommended list you will benefit from scientifically proven yield benefits and allow you to capitalise on the strengths of different species.
The benefits of a new ley will last many years over an existing one. However, these benefits will decline and will depend on the following factors:
The benefits of reseeding have a number of factors as well as improving yield and quality of the ley.
The productivity of a grass ley decreases over time and as the below table shows the yield of a 1 year ley can be as much as an additional 3.5t DM/ha compared to a five year ley.
The main reason for a reduction in productivity of a sward will largely be down to weed grass ingress. This can be as much as 50% after 5 years.
This graph highlights the potential yield losses from weed grasses compared to perennial ryegrass.
Perennial ryegrass and weed grass respond quite differently to nitrogen. You can see the comparison here:

Grazed grass when managed well will reduce input costs, especially bought in feed and gives excellent returns in terms of production and profit. Measuring pasture cover provides useful information for feed budgeting and rotation planning to optimise grazing management.
With the primary aim of providing a break between grass leys, root crops have also allowed one Carmarthenshire-based business to extend dwindling forage reserves.
