摘要: Abstract 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 N2O pasture systems can be described by soil-gas diffusivity (Dp/Do), its dependency on soil physical properties moisture dynamics. But studies linking aggregation, variation, Dp/Do emissions lacking. Using coarse (2–4 mm) fine (
