- Observation Sites receiving 5 to 10 mm of precipitation within 48 hours of seeding had no seed placed N damage.
- Intervention effect NBPT improved stand density in 20 of 31 trials with N induced reductions.
- Intervention effect No trials found greater seedling damage with NBPT treatment.
- Intervention effect NBPT improved yield in only eight trials.
- Recommendation The authors recommend increasing safe seed row N guidelines by 30 kg N ha -1 for barley.
- Recommendation The authors recommend increasing safe seed row N guidelines by 20 kg N ha -1 for canola.
- Recommendation The authors recommend increasing safe seed row N guidelines by 15 kg N ha -1 for wheat.
