“…This study also suggests that crop residue incorporation is not the best way to reduce CO 2 emissions, because no-tillage could reduce the crop residue decomposition rate (Li et al, 2010). Our results were different from those reported by Lee (2009). They reported that seasonal emission patterns were not much influenced by tillage; however, the results of this study corroborated with Krištof et al, (2014) and Prior et al (2004).…”

Conservation tillage management can improve soil moisture and reduce or increase soil CO 2 emission. Soil CO 2 flux rate, soil moisture, and the relationship between soil respiration and temperature on North China Plain throughout a 3-year period was determined. Tillage systems were rotary tillage without crop residues (CT), rotary tillage with crop residues incorporated into the soil in winter, and no-tillage with crop residues used as mulch in summer (TW), and rotary tillage with crop residues incorporated into the soil in summer and no-tillage with crop residues used as mulch in winter (TS). Soil respiration was measured with a LI-8100 and the gravimetric method was used to identify soil water content. Soil temperature at 5 cm depth also was measured directly by Li-8100 through a temperature sensing probe during the CO 2 measurement time. The crops were winter wheat (Triticum aestivum L) and summer maize (Zea mays L). During the wheat and maize growing period, TS reduced CO 2 emission when compared with CT and TW. For the first two years of this study, CT and TW had higher soil water content when compared with TS. Thus, this study suggests that conservation tillage can be useful for North China plain farmers; however, TW emitted CO 2 at the highest rate level, therefore further research is needed on long term effects of those three tillage practices on respiration rate and soil moisture in that area.

“…Barreto et al (2009) showed for instance a 700% increase in C-CO 2 emissions by using NT. This rate was as much as 29% in a study by Aslam et al (2000) in New Zealand, 15% in Brazil (Carmo et al, 2007), 9% by Smith et al (2011) in the USA, 5% by Sainju et al (2010) in the USA and 4% by Lee et al (2009) Version définitive du manuscrit publié dans / Final version of the manuscript published in : Agriculture, Ecosystems & Environment, 2015, 203, 110-118 http://dx.doi.org/10.1016/j.agee.2015 Manuscrit (Oorts et al, 2007). Since, in the present study no mulch was present on the soil surface, what can explain the greater C-CO 2 emissions from NT soils?…”

“…Several sources [11,27,28,30,[32][33][34][35][36] have reported that N 2 O is produced by the activation of both nitrification and denitrification processes. Groffman et al [31], Kanako et al [11], and Taghizadeh-Toosi et al [37] reported that nitrification activity is activated under low water conditions and that it is enhanced by the presence of NH 4 ?…”

The effect of water application (e.g., through rainfall or sprinkler system) on emissions of greenhouse gases (GHGs), such as nitrous oxide (N 2 O), methane (CH 4 ), and carbon dioxide (CO 2 ), from pen surfaces of open-lot beef cattle feedlots was evaluated under controlled laboratory conditions. Soil/manure samples were collected from several randomly selected pens from two beef cattle feedlots in Kansas and were used as simulated pen surfaces. Three treatments (i.e., dry and loose, moist and loose, and moist and compacted pen surface conditions) were considered, simulating surface conditions in the field after a typical rainfall event or water application with a sprinkler system. Soil/ manure and water were mixed within glass containers and analyzed for GHG emission using a photo-acoustic infrared multi-gas analyzer; emission rates were calculated from measured concentrations. GHG emissions from the dry soil/ manure samples were low, with mean values of 0.02, 0.00, and 45 mg m -2 h -1 for N 2 O, CH 4 , and CO 2 , respectively, compared to moist soil/manure samples. Water application on the dry manure samples resulted in large peaks of GHG fluxes, with peak values of 99.2, 28.6, and 15,443 mg m -2 h -1 for N 2 O, CH 4 , and CO 2 , respectively.Keywords Feedlot Á Surface emission Á Soil/manure drying process Á Greenhouse gas emission Á Rainfall effect
