“…8). This confirms the findings of Akiyama et al (2004), who found that N 2 O emission rate increased with increasing moisture, up to 80% WFPS. Similarly, Rochette et al (2008) observed increase in N 2 O emission rates when both NO 3 -N concentration and WFPS were high in soil.…”

“…The reason for the high NO3 − content could have been due to the stimulation of litter and organic matter decomposition and mineralization after the conversion from grassland to cornfield in November 2009. The manure N2O emission factors ranged from 0.2% to 0.9% and are similar to those reported by Collins et al [60] (0.05%-0.1%) and Akiyama et al [61] (0.01%-1.6%).…”

Despite both manure and inorganic fertilizers increasing N 2 O emissions, the manure-only treatments had significantly lower emissions than the inorganic fertilizer plot.…”

Abstract:A 3-year study was conducted in cornfield to evaluate how composted cattle manure application affects net global warming potential (GWP; the sum of nitrous oxide (N 2 O) and methane (CH 4 ) minus net ecosystem carbon balance (NECB)) and greenhouse gas intensity (GHGI; net GWP per unit of plant biomass yield). In the first experiment, conducted from 2010 to 2012, five fertilization strategies that included an unfertilized control plot, inorganic fertilizer-only plot, two plots with inorganic fertilizer plus composted cattle manure, and composted cattle manure-only plot were established. In the second experiment composted cattle manure was applied in autumn 2012 and the field was subdivided into three plots in spring 2013, with one plot receiving additional composted cattle manure, the second plot received additional inorganic fertilizer and the third plot did not receive any additional fertilization. Fluxes of N 2 O, CH 4 and CO 2 were measured using the static closed chamber method. NECB was calculated as carbon (C) inputs minus C output (where a negative value indicates net C loss). In experiment 1, manure application significantly increased NECB and reduced net GWP by more than 30% in each of the three years of the study. GHGI in the manure-amended plots was lower than in other plots, except in 2012 when the manure-only plot had higher GHGI than fertilizer-only plot. Application of inorganic fertilizer alone increased GWP by 5% and 20% in 2010 and 2011, but showed a 30% reduction in 2012 relative to the unfertilized control plot. However, due to higher net primary production (NPP), fertilizer-only plot had lower GHGI compared to the control. Application of inorganic fertilizer together with manure showed the greatest potential to reduce GWP and GHGI, while increasing NPP and NECB. In experiment 2, additional manure or inorganic fertilizer application in spring increased NPP by a similar amount, but additional manure application also increased NECB, and decreased GWP and GHGI. Manure application, as a partial substitute or supplemental fertilizer, shows potential to mitigate GWP and GHGI.

“…1(a)). The soil pore spaces filled with water would inhibit NO gas from transporting (Akiyama et al, 2004). In addition, wet precipitation can lower surface soil temperature, wash N fertilizer to deep soil, and change the structure of microbial community (Jackson et al, 2003).…”
