Publikováno v: New Zealand Journal of Agricultural Research. 57:316-331

The nitrification inhibitor dicyandiamide (DCD) has been reported to significantly reduce nitrate () leaching and nitrous oxide (N2O) emissions under urine patches in New Zealand trial conditions. However, results on the efficacy of DCD for increasin

Autor: C. J. Hoogendoorn, Alison Rutherford, Roger P. Littlejohn, S. A. Letica, C. A. M. de Klein, R. W. Tillman

Publikováno v: Animal Production Science. 50:17

The purpose of this short-term study was to investigate the effect of increasing fertiliser nitrogen (N) application rates on nitrous oxide (N2O) emissions over the late winter/early spring period from sheep-grazed pasture in Otago rolling hill count
