Trials show benefits of nitrification inhibitors across New Zealand

摘要

The Nitrous Oxide Mitigation Re-search (NOMR) trials commenced in autumn 2009. They were conducted in the Waikato (AgResearch Tokanui Research Farm), Manawatu (Mas-sey University), Canterbury (Lincoln University) and South Otago (Telford Farm) dairy regions.At each location there was a grazing trial to measure the effect of DCD treatment on pasture dry matter (DM) response, small plot trials to measure effects of DCD on nitrous oxide emissions, and DCD movement in soil beneath cattle urine patches, and also, in years two and three, measurement of the effects of DCD application on nitrate leaching.
