Denitrification in vadose zone material amended with dissolved organic matter from topsoil and subsoil
(Elsevier Ltd, 2013-06)
Limited information is available on the potential of subsoil and underlying alluvial gravels (vadose zone) to denitrify leached nitrate, though it is recognized that C availability is an important constraint. In this ...
Influence of soil bulk density and matric potential on microbial dynamics, inorganic N transformations, N₂O and N₂ fluxes following urea deposition
(Elsevier Ltd., 2013-10)
Transformation of ruminant urine-nitrogen (N) can contribute to negative environmental outcomes such as nitrate leaching which leads to eutrophication of waterways and production of nitrous oxide (N₂O), a greenhouse gas. ...
Soil-gas diffusivity and soil-moisture effects on N₂O emissions from intact pasture soils
(Wiley on behalf of the Soil Science Society of America, 2019-07)
Grazed pastures are recognized as a dominant source of nitrous oxide (N₂O), a highly potent greenhouse gas. Studies have examined soil physical controls on N₂O emissions, including soil moisture status. Limited attempts ...
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 ...
