Benefits of reseeding

Advice from our specialist Advice from our specialist9-4-2020

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 reseeding

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.

Reseeding benefits

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.
