Density effects on soil-water characteristics, soil-gas diffusivity, and emissions of N₂O and N₂ from a re-packed pasture soil
(Soil Science Society of America, 2019-02)
Density-induced soil structural changes may potentially alter both soil total porosity and soil pore size distribution, and thus change the soil’s water retention characteristics, gas diffusion and transport properties, ...
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 ...
Flooding-induced N₂O emission bursts controlled by pH and nitrate in agricultural soils
Agricultural soils are a major source of the greenhouse gas nitrous oxide (N₂O) to the atmosphere. Increasing frequency and severity of flooding as predicted for large intensively cropped areas may promote temporary ...
