Reduce Nitrogen Emissions

Develop and implement new production systems with a lower dependence on chemical Nitrogen fertilisers.

Immediate actions include:

  • Greater use of red and white clover in grazing systems
  • Improved soil fertility/health
  • Reduce crude protein in both bovine and pig diets
  • Develop precision grazing technologies and fertiliser technologies.


How Does It Work?

Clover fixes nitrogen from the atmosphere.  Nitrogen fixation is the name of this process whereby white clover can fix N from the atmosphere and make it available for plant growth, thereby reducing the requirement for chemical Nitrogen.

Benefits of white clover

The benefits of white clover tend to occur from May onwards as sward white clover content increases. The main benefits of white clover inclusion in grass swards are:

    • Increased herbage quality compared to grass-only swards in the summer months.
    • Increased dry matter (DM) intake in summer and autumn.
    • Higher milk production and live weight gain.
    • Nitrogen fixation – white clover fixes nitrogen (N) from the atmosphere making it available for plant growth.

Reduce crude protein in animal diets

A 1% reduction in the Crude Protein of dairy rations could potentially reduce Nitrogen excretions by 1% and also result in a 5% reduction in GHG and ammonia emissions.
