e0“AV applied with urea was 61.4 and 57.3% higher than that with CRU in 2010–2011 and 2011–2012”
e1“The AV applied with CRU and urea predominately occurred at the rice flooding period, which accounted for 83.2 to 86.6% and 95.5 to 96.9% of AV at the entire rice season”

Other claims from this paper (9)
- Intervention effect Ammonia volatilization with urea was 57.3% higher than with controlled-release urea in 2011–2012.
- Observation Ammonia volatilization under controlled-release urea occurred mainly in the rice flooding period, at 83.2 to 86.6% of rice-season volatilization.
- Observation Ammonia volatilization under urea occurred mainly in the rice flooding period, at 95.5 to 96.9% of rice-season volatilization.
- Association Rainfall significantly reduced ammonia volatilization during rice growth.
- Association Rainfall before N fertilization could significantly increase ammonia volatilization in the wheat season.
- Intervention effect Urea and controlled-release urea showed no obvious difference in grain yield, N concentration and removal N of aboveground biomass.
- Recommendation Controlled-release urea should be recommended for use during the rice flooding period to decrease the ammonia volatilization rate.
- Intervention effect Controlled-release urea is an effective technique in minimizing ammonia volatilization compared with urea.
- Recommendation Irrigation and rainfall should be considered when designing N fertilization programs in rice to decrease ammonia volatilization.
