Benefits of reseeding
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.
Assess the sward
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:
- New improved varieties
- Increased palatability
- Increased protein
- Improved nitrogen efficiency
- Reduced nitrogen requirement
- Review soil compaction and any weed issues
- Less disease – cycles are broken
Weed grasses in the sward
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:
