By using new improved varieties can give you 33% more yield than a typical five year ley. Over the next four leys, the DM yield will be 10% higher. Reseeding will therefore improve yield and quality whilst reducing bought in feed requirements.
The benefits of a new ley will last many years compared to an existing one. However, over time these benefits will decline and will depend on:
Nutrition - Maintaining the swards nitrogen, phosphate, potash and sulphur requirements.
Soil Health – Maintaining the correct pH and avoiding compaction
Weed Control – Maintaining an appropriate weed control programme
Grassland Management – Reducing ingress of native species (weed grasses) which are of a lower production and nutritional quality.
The benefits of reseeding include:
The amount of weed grasses in the sward increases over time reducing productivity.
The potential yield losses from weed grasses compared to perennial ryegrass can be seen below:
The perennial ryegrass and weed grass response to nitrogen is shown below:

A structured approach to silaging will improve forage quality as well as improving milk from forage.
A soil test is important for a number of reasons but are you aware that there is a legal requirement to test your soil, on cultivated land a minimum of every 5 years?
