Competition and community succession link N transformation and greenhouse gas emissions in urine patches
Nitrous oxide (N₂O) is a strong greenhouse gas produced by biotic/abiotic processes directly linked to both fungal and prokaryotic communities that produce, consume or create conditions leading to its emission. In soils ...
Temperature alters dicyandiamide (DCD) efficacy for multiple reactive nitrogen species in urea-amended soils: Experiments and modeling
Dicyandiamide (DCD) is a nitrification inhibitor (NI) used to reduce reactive nitrogen (N) losses from soils. While commonly used, its effectiveness varies widely. Few studies have measured DCD and temperature effects on ...
Gross N transformations vary with soil moisture and time following urea deposition to a pasture soil
Ruminant urine patches in grazed grasslands significantly change the chemical and biological properties of the affected soils due to the predominance of urea within ruminant urine and the high rates deposited onto pastures. ...
Identification and verification of key functional groups of biochar influencing soil N₂O emission
(Springer Nature, 2021-01-26)
Biochars containing abundant and diverse functional groups can influence soil nitrous oxide (N₂O) emissions. It remains unclear how these functional groups alter soil N₂O emissions and which specific functional groups are ...
Recent advances in grazed pasture-based dairy science
(Taylor & Francis on behalf of the Royal Society of New Zealand, 2021-01-13)
It is a pleasure to present this special issue of the New Zealand Journal of Agricultural Research which focuses on recent research in dairy science relating to grazed pasture, covering the rearing of stock, genetics and ...
Effect of aggregate size distribution on soil moisture, soil-gas diffusivity, and N₂O emissions from a pasture soil
Grazed pastures rich in nitrogen (N) from ruminant urine and fertilizer inputs are significant sources of nitrous oxide (N2O), a highly potent greenhouse gas. Diffusion-controlled emission of N2O from pasture systems can ...
