07 313 89283 pr.grace@qut.edu.au Metadata Provider The impact of nitrogen (N) fertiliser management on nitrous oxide (N2O) emissions, wheat yield and N uptake was studied at Tarrington, in south west Victoria. Management included five different rates of N fertiliser (0, 25, 50, 100 and 200 kg N/ha) applied as granular urea; two different timings of N, either deep banded 10 cm below the seed at sowing or top-dressed at first node growth stage; and the nitrification inhibitor DMPP (3,4-Dimethylpyrazole phosphate) coated to urea (ENTEC®). Pre-sowing profile soil chemical properties were determined before static chambers were used to measure N2O losses, accompanied by wheat yield and N uptake to quantify differences between N management. nitrous oxide wheat nitrogen use efficiency static chamber ENTEC 3,4-Dimethylpyrazole phosphate Urea Data will be published by the principal research organisation (DEPI Victoria); but will be made available for simulation modelling purposes and formulation of emission factors.
