- Observation At GS 25 plus 15 days, non-recovered nitrogen reached 33 kg per hectare at the lower nitrogen rate.
- Observation At GS 25 plus 15 days, non-recovered nitrogen reached 74 kg per hectare at the higher nitrogen rate.
- Association Sowing density did not affect non-recovered nitrogen.
- Observation Later remineralization indicated earlier non-recovered nitrogen had been immobilized.
- Association Nitrogen uptake from later applications was lowest at low sowing density.
- Association Non-recovered nitrogen at harvest was highest at low sowing density.
- Association Non-recovered nitrogen was similar at common and high sowing densities.
- Observation Highest grain yields occurred at common sowing density with 43 + 30 + 60 kg N per hectare dressings.
- Association High sowing density yielded less grain than common sowing density.
- Association Changing sowing density from common practice did not reduce fertilizer nitrogen immobilization and losses.
- Association Changing sowing density from common practice did not increase grain yields.
