Other claims from this paper (17)
- Observation Low rainfall limited plant growth and microbial processes through soil water availability.
- Intervention effect DMPP reduced topsoil nitrate concentration by 28% on average.
- Intervention effect DMPP reduced cumulative N2O losses by 82%.
- Observation Most N2O emissions occurred during the growing season.
- Observation The annual emission factor was 0.07% for manure with DMPP.
- Observation The annual emission factor was 0.95% for manure without DMPP.
- Intervention effect Cumulative N2O emissions were 40% higher under lower rainfall than under added rainfall.
- Intervention effect DMPP had no reported effect on annual nitrate leaching losses.
- Intervention effect Rainfall amount had no reported effect on annual nitrate leaching losses.
- Observation Annual nitrate leaching losses corresponded to 12% of manure nitrogen.
- Observation Annual nitrate leaching losses were mainly driven by the post-harvest period.
- Intervention effect DMPP did not affect maize yield.
- Intervention effect DMPP did not affect nitrogen use efficiency.
- Intervention effect Low rainfall severely reduced maize biomass.
- Intervention effect Low rainfall severely reduced maize nitrogen use efficiency.
- Observation The authors conclude that dry growing seasons can jeopardize crop production while increasing greenhouse gas emissions.
- Recommendation The authors recommend nitrification inhibitors under dry conditions to address climate impacts.
