Other claims from this paper (7)
- Intervention effect Some morning urea spray treatments had lower apparent crop N recovery in 1992 and 1994 than soil-applied N.
- Association A large sprayed-urea share associated with later application increased physiological N use efficiency in 1992.
- Intervention effect In 1993 direct fertilizer N recovery in crop or soil did not differ across ammonium nitrate, solid urea and sprays.
- Intervention effect In 1993 apparent fertilizer N recovery in crop or soil did not differ across the fertilizer treatments.
- Intervention effect N treatments elevated drainage-water nitrate concentration in every year.
- Association In 1992 increasing the urea-spray share decreased drainage-water nitrate concentration.
- Recommendation The authors suggest cool evening urea sprays to reduce gaseous and total N losses.
