Other claims from this paper (5)
- Observation Grass-only swards yielded 7,682 kg DM/ha per year.
- 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.
- Mechanism Background N mineralisation of 185 kg N/ha arises from the soil organic matter in grass-only and grass-clover swards receiving zero N.
- Observation White clover fixed 99 kg N/ha biologically in zero-N swards.
