“…Our results were consistent with those of other reports that SCE increased by 2-15 times after tillage (Reicosky et al 1997;Calderon et al 2001;Reicosky 2002;Morris et al 2004;La Scala et al 2005;Gesch et al 2007;Alvaro-Fuentes et al 2007). Reicosky et al (1997) found that the increase in SCE seen immediately after tillage was the result of a physical release of CO 2 entrapped in soil pores rather than changes in microbial activity at the time of tillage. Although the burst immediately following tillage in 2006 and 2007 might be partly explained by physical release of the CO 2 , this physical process could not explain the sustained long-term increase in SCE observed in the present study.…”

“…The SCE peaks occurring after tillage might have been due to the fact that (1) tillage incorporates residue into soil, increases microbial substrates and stimulates mineralization of soil organic materials (Alvarez et al 2001;Zhang et al 2011); (2) tillage improves soil aeration and increases contact between soil and crop residues (Alvaro-Fuentes et al 2007); and (3) tillage disrupts soil aggregates and exposes aggregate-protected organic matter to microbial attack (Beare et al 1994;Kristensen et al 2000;Kladivko 2001). Our results were consistent with those of other reports that SCE increased by 2-15 times after tillage (Reicosky et al 1997;Calderon et al 2001;Reicosky 2002;Morris et al 2004;La Scala et al 2005;Gesch et al 2007;Alvaro-Fuentes et al 2007).

“…Some studies have shown that higher SCE occurred frequently after tillage (Reicosky et al 1997;Morris et al 2004;La Scala et al 2006;Gesch et al 2007). For example, the SCE increased 13.8 times after moldboard tillage in a clay loam soil in the Northern Cornbelt of the United States (Reicosky et al 1997). Additionally, in a semi-arid Mediterranean agroecosystem in Spain, the SCE measured immediately after tillage was 3-15 times higher than that before tillage (Alvaro-Fuentes et al 2007).…”

“…These practices change the soil surface covering, as well as the soil physical, chemical and biological properties, including soil microbial activities, which subsequently influences SCE.

An automated chamber system was employed to measure the soil CO 2 efflux (SCE) in situ for 2 years in a conventional wheat field of the Loess Plateau, China under semi-arid conditions. The annual mean SCE values were 2.44 ± 2.52 lmol m À2 s À1 in 2006 and 2.37 ± 2.33 lmol m À2 s À1 in 2007. Distinct seasonality in the SCE was observed, with significant differences occurring among four periods divided by harvesting, tillage and sowing. In the period from tillage to sowing, the mean SCE values were 2.82 and 2.69 times the annual mean values in 2006 and 2007, respectively, and SCE accounted for 39% and 48% of the annual total within 14% and 18% of the days of the years. Although there were significant exponential correlations between the SCE and soil temperature, and significant linear correlations between the SCE and soil moisture for measurements conducted in the periods before tillage and after sowing each year, the SCE from tillage to sowing was significantly beyond the correlation curves. These findings indicated that seasonal variation in the SCE in a conventional field was controlled not only by soil temperature and moisture, but also by tillage practice. The confounding effects of climate and practice on SCE should be considered when developing ways to mitigate soil carbon loss in conventional cropland in semi-arid regions.

“…On this date, no-tillage had 47 % greater soil surface CO 2 flux than that under conventional tillage, with respective readings of 1.07 and 0.73 μmol CO 2 m −2 s −1 . Results from this sampling date are different from what was expected based on past studies that reported greater CO 2 flux under conventional tillage than that measured under reduced and no-tillage treatments (Reicosky and Lindstrom 1993;Reicosky et al 1997;West and Marland 2002). These results were also contrary to results in a study evaluating a soybean-wheat rotation on a silt-loam soil in a similar geographic location of east-central Arkansas, which reported a 38 % greater soil surface CO 2 flux under conventional tillage than from that under no-tillage (Brye et al 2006b).…”

Carbon dioxide (CO 2 ) emitted from the soil, as a result of root and microorganism respiration, is a major process in the global carbon cycle. Since CO 2 production is dependent on oxygen availability, prolonged saturated soil conditions in rice (Oryza sativa) can decrease the quantity of soil carbon released in the form of CO 2 over time. At present, a deficiency exists in the scientific literature on soil surface CO 2 flux in well-established, flood-irrigated rice systems, which are flooded for approximately 3 months a year during the rice growth period. Plenty of studies have examined soil surface CO 2 flux in dryland cropping systems and methane emissions in paddy-grown rice, but flood-irrigated rice does not easily fall into either of these categories due to the cyclic nature of seasonal flooding. Therefore, this is the first study to examine daily soil surface CO 2 flux during non-flooded periods in well-established, flood-irrigated rice rotations. For a comprehensive analysis, soil surface CO 2 flux was measured for 2 years on 10 different rice-based rotations, which had been managed using conventional tillage or no-tillage for 10 and 11 years. Rotations included continuous rice and various combinations of rice rotated with soybean (Glycine max), corn (Zea mays), and/or winter wheat (Triticum aestivum) and were located on a silt-loam soil in the Mississippi River Delta region of Arkansas in the USA. Results showed that 7 of the 16 measurement dates differed in daily soil surface CO 2 flux among tillage and/or crop rotations. However, these differences were determined to be from crop maturity, in relation to early-or late-season planting, instead of patterns of long-term flood irrigation. Years that rice was grown reduced the cumulative CO 2 emissions, but substantial differences over time were minimized in rotations with soybean or corn. Findings from this experiment are valuable in the scientific understanding of carbon gas cycling in rice-based cropping systems because the aerobic periods between flooding were evaluated, which is the time period often ignored when examining carbon gas emissions in rice. Overall, this study provides evidence that the commonly used rice-based cropping systems reach a somewhat equilibrium state in daily CO 2 fluxes over time, regardless of the frequency in periodic soil saturation.

The increase in corn (Zea mays L.) and soybean [Glycine max (L.) Merr.] production in rainfed cropping systems of the northern Great Plains (NGP) has altered the delivery of ecosystem services from agricultural land. To date, there is limited understanding about how these crops affect the carbon (C) balance of cropping systems in the region when included in a short rotation window. This study sought to quantify C balance of a spring wheat (Triticum aestivum L.)–corn—soybean rotation under no‐tillage management using eddy covariance (EC) techniques. Paired field sites with the same soil type near Mandan, ND, were used for the study. Annual net ecosystem production (NEP) by crop was –34, 120, and 7 g C m–2 y–1 for spring wheat, corn, and soybean, respectively. Carbon removed in grain over the rotation was less than a third of C lost by ecosystem respiration (ER) (210 vs. 674 g C m–2 y–1). After accounting for grain C removal, net ecosystem carbon balance (NECB) was –164, –253, and –121 g m–2 y–1 for spring wheat, corn, and soybean, respectively, with a mean NECB of –179 ± 39 g C m–2 y–1 (P = .043; t test for difference from zero), implying the rotation was a net C source. Time associated with active crop growth each year was 27% for spring wheat, 41% for corn, and 28% for soybean. Management strategies that lengthen the period of biomass growth may mitigate C loss from spring wheat–corn–soybean rotations in the NGP.
