Effects of nitrogen application rate and a nitrification inhibitor dicyandiamide on methanotroph abundance and methane uptake in a grazed pasture soil

Dai, Y.; Di, Hong J.; Cameron, Keith C.; He, J.-Z. (Springer-Verlag Berlin Heidelberg, 2013-12)

Methane-oxidizing bacteria (methanotrophs) in the soil are a unique group of methylotrophic bacteria that utilize methane (CH4) as their sole source of carbon and energy which limit the flux of methane to the atmosphere ...

Assessing the impact of non-urea ruminant urine nitrogen compounds on urine patch nitrous oxide emissions

Gardiner, Camilla; Clough, Timothy J.; Cameron, Keith C.; Di, Hong J.; Edwards, Grant; de Klein, C. A. M. (American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, 2018-07)

Urea, the dominant form of N in ruminant urine, degrades in soil to produce N2O emissions. However, the fate of non-urea urine N compounds (NUNCs) in soil and their contribution to urine patch N2O emissions remain unclear. ...
