- Intervention effect NBPT 1-treated urea reduces total ammonia volatilization loss by 29.1–78.8% during the 20 days after N application.
- Intervention effect NBPT 2-treated urea reduces total ammonia volatilization loss by 35.4–81.9% during the 20 days after N application.
- Intervention effect NBPT 3-treated urea reduces total ammonia volatilization loss by 77.3–87.4% during the 20 days after N application.
- Intervention effect Polymer coated urea reduces total ammonia volatilization loss by 59.1–83.3% during the 20 days after N application.
- Intervention effect NBPT 1-treated urea increases corn grain yield by 15.6–31.4%.
- Intervention effect NBPT 2-treated urea increases corn grain yield by 12.9–34.8%.
- Intervention effect NBPT 3-treated urea increases corn grain yield by 18.7–19.9%.
- Intervention effect Polymer coated urea increases corn grain yield by 14.6–41.1%.
- Intervention effect Maleic-itaconic copolymer treated urea is ineffective in reducing ammonia volatilization loss.
- Intervention effect NBPT-treated urea improves N nutrition, grain yield and N agronomic use efficiency of corn.
- Intervention effect Polymer coated urea improves N nutrition, grain yield and N agronomic use efficiency of corn.
- Intervention effect Increasing NBPT from 20% to 30% does not improve its inhibitory effect on ammonia volatilization.
- Intervention effect UAN treated with a combination of urease and nitrification inhibitors yields 16.5–16.6% more corn than untreated UAN, only when surface applied.
- Recommendation Under no-tillage with surface-applied urea fertilizers, an effective urease inhibitor can enhance use efficiency and performance on corn where urea N losses are noticeable.
