Other claims from this paper (10)
- Intervention effect DMPP decreased topsoil nitrate concentrations by 28% on average in the maize lysimeter experiment.
- Intervention effect DMPP decreased cumulative N2O losses by 82%.
- Intervention effect Cumulative N2O emissions were 40% higher without simulated rainfall (R-) than with it (R+).
- Intervention effect DMPP had no effect on annual nitrate leaching losses.
- Intervention effect Rainfall amount had no effect on annual nitrate leaching losses.
- Observation Annual nitrate leaching losses corresponded to 12% of manure-N and were mainly driven by the post-harvest period.
- Intervention effect DMPP did not affect maize yield or nitrogen use efficiency.
- Intervention effect Absence of simulated rainfall (R-) caused severe reductions in biomass and nitrogen use efficiency.
- Observation Soil water availability was a limiting factor for plant growth and microbial processes because of low rainfall in the growing season.
- Recommendation The use of nitrification inhibitors is strongly recommended under dry growing-season conditions.
