- Association Grass-white clover swards yielded significantly higher herbage (10,166 kg DM/ha per year) than grass-only swards.
- Association Grass-white clover swards took up significantly more N (284 kg N/ha per year) than grass-only swards.
- Observation White clover fixed 99 kg N/ha biologically in zero-N swards.
