Emissions of N2O and NH3, and nitrogen leaching from direct seeded rice under different tillage practices in central China

▶ Application of N fertilizers significantly increase emissions of N2O and NH3, and N leaching. ▶ N2O emissions, NH3 volatilization and N leaching from rice fields are affected by tillage practices. ▶ Application of N fertilizer in combination with no-tillage increases N losses from rice field.
