Journal ArticleDOI
Nitrate leaching in temperate agroecosystems: sources, factors and mitigating strategies
Hong J. Di,Keith C. Cameron +1 more
TL;DR: In this article, the evidence of NO3ⓘ− leachinglosses from various land use systems, including cut grassland, grazed pastures, arable cropping, mixed cropping with pasture leys, organic farming, horticultural systems, and forest ecosystems are discussed.
Journal ArticleDOI
Nitrogen losses from the soil/plant system: a review
TL;DR: It is shown that careful management of temperate soil/plant systems using best management practices and newly developed technologies can increase the sustainability of agriculture and reduce its impact on the environment.
Journal ArticleDOI
Nitrification driven by bacteria and not archaea in nitrogen-rich grassland soils
Hong J. Di,Keith C. Cameron,Ju-Pei Shen,Christopher S. Winefield,M M O'Callaghan,Saman Bowatte,Ji-Zheng He +6 more
TL;DR: It is suggested that nitrification is driven by bacteria rather than archaea in these nitrogen-rich grassland soils in New Zealand, with a significant relationship between the abundance of ammonia-oxidizing bacteria and the rate of nitrification.
Journal ArticleDOI
Ammonia‐oxidizing bacteria and archaea grow under contrasting soil nitrogen conditions
Hong J. Di,Keith C. Cameron,Ju-Pei Shen,Christopher S. Winefield,Maureen O'Callaghan,Saman Bowatte,Ji-Zheng He +6 more
TL;DR: Investigation of AOB and AOA growth and nitrification rate in two different layers of three grassland soils treated with animal urine substrate and a nitrification inhibitor shows that AOB were more abundant in the topsoils than in the subsoils, whereas AOA were more scarce in one of the subSOils.
Journal ArticleDOI
The use of a nitrification inhibitor, dicyandiamide (dcd), to decrease nitrate leaching and nitrous oxide emissions in a simulated grazed and irrigated grassland
Hong J. Di,Keith C. Cameron +1 more
TL;DR: In this paper, the authors used lysimeters to measure the effectiveness of a nitrification inhibitor, dicyandiamide (DCD), in decreasing NO - 3 leaching and N 2 O emissions from urine patches in a grazed dairy pasture under irrigation.
