Sixty years of seasonal irrigation affects carbon storage in soils beneath pasture grazed by sheep

Kelliher, Francis M.; Condron, Leo M.; Cook, F. J.; Black, Amanda (Elsevier BV, 2012-02-15)

For sixty years at Winchmore, South Island, New Zealand (43°48′S, 171°48′E, 160 masl), stoney soils under continuous pasture grazing by sheep have received rainfall (nil irrigation) or rainfall and irrigation as required ...

Increasing soil aeration reduces mitigation efficacy of dicyandiamide when targeted at ruminant urine-derived N₂O emissions

Balaine, Nimlesh; Clough, Timothy J.; Kelliher, Francis M.; Van Koten, C. (Taylor & Francis on behalf of the Royal Society of New Zealand, 2015-10-11)

Soil aeration effects on the efficacy of dicyandiamide (DCD) at reducing reactive nitrous oxide (N₂O) fluxes from ruminant urine patches have not been assessed. We tested the null hypothesis that increasing soil aeration ...

Nitrous oxide emissions from in situ deposition of ¹⁵N-labeled ryegrass litter in a pasture soil

Pal, Pranoy; Clough, Timothy J.; Kelliher, Francis M.; Sherlock, Robert R. (Crop Science Society of America, Soil Science Society of America and American Society of Agronomy, 2013-03)

During pasture grazing, freshly harvested herbage (litterfall) is dropped onto soils from the mouths of dairy cattle, potentially inducing nitrous oxide (N₂O) emissions. Although the Intergovernmental Panel on Climate ...

Soil aeration affects the degradation rate of the nitrification inhibitor dicyandiamide

Balaine, Nimlesh; Clough, Timothy J.; Kelliher, Francis M.; van Koten, C. (CSIRO Publishing, 2015)

© CSIRO 2015. Dicyandiamide (DCD) is a nitrification inhibitor of variable efficacy. In soils, DCD biodegradation rate is known to be a function of temperature; however, microbial activity can also be affected by soil ...
