Other claims from this paper (8)
- Intervention effect Double inhibitor reduced ammonia volatilization by 34% versus urea in 2015.
- Intervention effect Double inhibitor reduced nitrous oxide emissions by 43% versus urea in 2015.
- Intervention effect Nitrification inhibitor reduced nitrous oxide emissions by 53% versus urea.
- Intervention effect Nitrification inhibitor had similar ammonia loss to urea.
- Intervention effect Double inhibitor reduced ammonia loss by 48% versus nitrification inhibitor.
- Association Nitrous oxide fluxes were higher at 35 to 60% water-filled pore space, warmer soil and elevated soil nitrate.
- Intervention effect Grain and protein yields were similar across urea and inhibitor treatments.
- Recommendation The authors suggest combined urease and nitrification inhibitors to reduce nitrogen losses while maintaining yields.
