t0“improves nitrogen use efficiency in maize”
e0“Maize was grown to maturity on two contrasting soils (acidic Cambisol and neutral Chernozem) in pots with a treatment of biochar co-applied with ammonium sulphate stabilised by a nitrification inhibitor (3,4-dimethylpyrazole-phosphate, DMPP) or un-stabilised”
e1“The combination of biochar with ammonium sulphate containing DMPP increased maize biomass yield up to 14%, N uptake up to 34% and NUE up to 13.7% compared to the sole application of ammonium sulphate containing DMPP”

Other claims from this paper (7)
- Intervention effect Biochar combined with DMPP-stabilised ammonium sulphate increased maize N uptake by up to 34% compared with the sole stabilised fertiliser.
- Intervention effect Biochar combined with DMPP-stabilised ammonium sulphate increased nitrogen use efficiency by up to 13.7% compared with the sole stabilised fertiliser.
- Intervention effect Biochar combined with un-stabilised ammonium sulphate increased maize biomass by 3.8% in acidic Cambisol only.
- Intervention effect Biochar combined with un-stabilised ammonium sulphate increased maize N uptake by 27% in acidic Cambisol only.
- Intervention effect Biochar combined with un-stabilised ammonium sulphate increased NUE by 11% in acidic Cambisol only.
- Intervention effect Biochar increased the uptake of phosphorus and potassium in both stabilised and un-stabilised ammonium sulphate treatments.
- Recommendation The combination of biochar with DMPP-stabilised ammonium sulphate may lead to higher efficiency of fertilisation practices and allow less N fertiliser to be applied.
