“…Similar CO 2 emissions rates were found with surface wheat residue in Luvisol with a peak emission at the 3 rd DAI and an exponential decrease until the end of the experiment at 56 DAI (Guillou et al, 2011). Cayuela et al (2009) found similar peaks in CO 2 emissions working with surface cotton residue on Regosol incubated for 25 days.…”

The decomposition/mineralization of organic material from crop residues constitutes an important nutrient reservoir for plants. This process produces CO 2 and is influenced by biophysical and environmental conditions such as temperature, oxygen availability and the chemical composition of the crop residue. We studied the effect of temperature and nitrogen fertilization on CO 2 emissions and the distinct contributions of C from sugarcane residue either left on the surface or incorporated into the redyellow Oxisol. Incorporated sugarcane residue and N applications produce higher total organic carbon (TOC) mineralization rates when compared to application on the soil surface and without N. Nevertheless, there was no difference between TOC and C in the humin fraction (C-HU) 80 days after incubation. CO 2 emissions peaked at 5.45, 10.82, 14.00, 11.92 and 11.20, 14.47, 15.98,and 14.74 µg mol of CO 2 g -1 s -1 within the first four days of incubation for unincorporated and incorporated residues, respectively. After these first four days, emissions decreased until stabilizing at 40 days after incubation.

“…5 Correlation between microbial biomass carbon (C-Mic) and cumulative emission of CO 2 -C (g C-CO 2 m −2 h −1 ) of soil with residue of soybean, Brachiaria, sugarcane, and treatment control in two contributions of the residue crops in agronomic rate (AR) and constant rate (CR) in 48 days after incubation (Franzluebbers et al 1994;Wang et al 2004), considered as an initial rapid phase (Duong et al 2009). Soil CO 2 -C emission peaks after 3 days of incubation followed by an exponential decrease until the end of the experiment with 56 days of incubation were obtained by Guilou et al (2011) working with CO 2 -C emission rates in Luvisol with surface addition of wheat residue. Cayuela et al (2009), evaluating cotton wool incubated on the surface of a Regosol for 25 days, also showed that initial peak in the emission of CO 2 -C, as did Almeida et al (2014) incubating sugarcane residue in Latosol for 79 days.…”

Purpose The mineralization/immobilization of nutrients from the crop residues is correlated with the quality of the plant material and carbon compartments in the recalcitrant and labile soil fractions. The objective of this study was to correlate the quality and quantity of crop residues incubated in the soil with carbon compartments and CO 2 -C emission, using multivariate analysis. Materials and methods The experiment was conducted in factorial 4 + 2 + 5 with three replicates, referring to three types of residues (control, sugarcane, Brachiaria, and soybean), and two contributions of the crop residues in constant rate, CR (10 Mg ha −1 residue), and agronomic rate, AR (20, 8, and 5 Mg ha −1 residue, respectively, for sugarcane, soybean, and Brachiaria), evaluated five times (1, 3, 6, 12, and 48 days after incubation). At each time, we determined the CO 2 -C emission, nitrogen and organic carbon in the soil, and the residues. In addition, the microbial biomass and water-soluble, labile, and humic substance carbons fractionated into fulvic acids, humic acids and humin were quantified.Results and discussion Higher CO 2 -C emissions occurred in the soil with added residue ranging from 0.5 to 1.1 g CO 2 -C m −2 h −1 in the first 6 days of incubation, and there was a positive correlation with the less labile organic soil fractions as well as residue type. In the final period, after 12 days of soil incubation, there was a higher relation of CO 2 -C emission with carbon humin. The sugarcane and soybean residue (20 Mg ha −1 ) promoted higher CO 2 -C emission and the reduction of carbon residue. The addition of residue contributed to an 82.32 % increase in the emission of CO 2 -C, being more significant in the residue with higher nitrogen availability. Conclusions This study shows that the quality and quantity of residue added to soil affects the carbon sequestration and CO 2 -C emission. In the first 6 days of incubation, there was a higher CO 2 -C emission ratio which correlates with the less stable soil carbon compartments as well as residue. In the final period of incubation, there is no effect of quality and quantity of residue added to soil on the CO 2 -C emission.

One of the most significant contributors to the greenhouse effect is carbon dioxide (CO 2 ) gas in the atmosphere. Soil respiration, the combined production of CO 2 from soil, as a result of root and microorganism respiration, is the largest flux of CO 2 from the terrestrial ecosystem to the atmosphere. Considering land use can greatly impact soil C storage and cycling, agricultural management practices can also greatly affect soil respiration and CO 2 emissions. Therefore, the effects of long-term residue management (i.e., residue burning and nonburning, and conventional [CT] and no-tillage [NT]) and residue level (i.e., high and low) on soil respiration during the soybean [Glycine max (L.) Merr.] growing season were examined over 2 consecutive years (i.e., 2011 and 2012) in a wheat (Triticum aestivum L.)-soybean, double-crop system in a silt-loam soil (Aquic Fraglossudalf) in the Mississippi River Delta region of eastern Arkansas after more than 9 years of consistent management. Soil respiration rates from individual plots ranged from 0.53 to 40.7 and from 0.17 to 13.1 μmol CO 2 ·m −2 ·s −1 throughout the 2011 and 2012 soybean growing seasons, respectively, and differed (P < 0.05) among treatment combinations on two and five of nine and 11 measurement dates in 2011 and 2012, respectively. Regardless of residue level, soil respiration was generally greater (P < 0.05) from CT than NT. Estimated season-long CO 2 emissions were 10.2% less (18.5 Mg CO 2 ·ha −1 ) from residue burning than from nonburning (20.6 Mg CO 2 ·ha −1 ; P = 0.032). Averaged over years and all other field treatments, estimated season-long CO 2 emissions were 15.5% greater from CT (21.0 Mg CO 2 ·ha −1 ) than from NT (18.
