“…Results from a 30-year maize experiment indicate that restitution of maize stalks vs. removal for silage had no impact on SOC contents (Reicosky et al, 2002). Although some studies have observed a significant contribution of crop shoot residues to SOC content (Barber, 1979;Hooker et al, 1982), this contribution was comparatively smaller than that of roots (Barber, 1979). Little impact of shoot residues on SOC was also observed in long-term residue burning studies (Moss and Cotterill, 1985;Nuttal et al, 1986 in Prasad andPower, 1991;Pikul and Allmaras, 1986;Rasmussen et al, 1980).…”

Understanding the origin of the carbon (C) stabilised in soils is crucial in order to device management practices that will foster C accumulation in soils. The relative contributions to soil C pools of roots vs. shoots is one aspect that has been mostly overlooked, although it appears a key factor that drives the fate of plant tissue C either as mineralized CO 2 or as stabilized soil organic matter (SOM). Available studies on the subject consistently indicate that root C has a longer residence time in soil than shoot C. From the few studies with complete datasets, we estimated that the mean residence time in soils of root-derived C is 2.4 times that of shoot-derived C. Our analyses indicate that this value is biased neither by an underestimation of root contributions, as exudation was considered in the analysis, nor by a priming effect of shoot litter on SOM. Here, we discuss the main SOM stabilisation mechanisms with respect to their ability to specifically protect root-derived SOM. Comparing in situ and incubation experiments suggests that the higher chemical recalcitrance of root tissues as compared to that of shoots is responsible for only a small portion, i.e. about one fourth, of the difference in mean residence time in soils of root-derived vs. shootderived C. This suggests that SOM protection mechanisms other than chemical recalcitrance are also enhanced by root activities: (1) physico-chemical protection, especially in deeper horizons, (2) micrometer-scale physical protection through myccorhiza and root-hair activities, and (3) chemical interactions with metal ions. The impact of environmental conditions within deeper soil layers on root C stabilisation appear difficult to assess, but is likely, if anything, to further increase the ratio between the mean residence time of root vs. shoot C in soils. Future advances are expected from isotopic studies conducted at the molecular level, which will help unravel the fate of individual shoot and root compounds, such as cutins and suberins, throughout soil profiles.

“…Several studies have measured emission of gaseous and particulate pollutants to the atmosphere during burning of crop residues (e.g., Oanh et al 2011;Park et al 2013;Hayashi et al 2014) and provided large-scale estimates of those emission rates (e.g., Streets et al 2003;Sahai et al 2011), while others have examined soil properties (e.g., Wuest et al 2005;Virto et al 2007) and crop productivity (e.g., Williams et al 1972;Hooker et al 1982) after continuous crop residue or stubble burning. However, few studies have investigated the chemical characteristics of crop residues after field burning and their impacts on rates of carbon dioxide (CO 2 ) and nitrous oxide (N 2 O) emission from soil after subsequent incorporation of the burned crop residues.…”

In the context of sustainable soil-quality management and mitigating global warming, the impacts of incorporating raw or field-burned adzuki bean (Vigna angularis (Willd.) Ohwi & Ohashi) and wheat (Triticum aestivum L.) straw residues on carbon dioxide (CO 2 ) and nitrous oxide (N 2 O) emission rates from soil were assessed in an Andosol field in northern Japan. Losses of carbon (C) and nitrogen (N) in residue biomass during field burning were much greater from adzuki bean residue (98.6% of C and 98.1% of N) than from wheat straw (85.3% and 75.3%, respectively). Although we noted considerable inputs of carbon (499 ± 119 kg C ha -1 ) and nitrogen (5.97 ± 0.76 kg N ha -1 ) from burned wheat straw into the soil, neither CO 2 nor N 2 O emission rates from soil (over 210 d) increased significantly after the incorporation of field-burned wheat straw. Thus, the field-burned wheat straw contained organic carbon fractions that were more resistant to decomposition in soil in comparison with the unburned wheat straw. Our results and previously reported rates of CO 2 , methane (CH 4 ) and N 2 O emission during wheat straw burning showed that CO 2 -equivalent greenhouse gas emissions under raw residue incorporation were similar to or slightly higher than those under burned residue incorporation when emission rates were assessed during residue burning and after subsequent soil incorporation.

“…Effective mitigation of these effects depends on developing crop residue management strategies that enhance residues decomposition. Realizing the potential benefits of cereal residues incorporation depends on synchronizing the release of N with the crop demands, while minimizing the risks to nutrient losses (Powlson et al, 1985;Hooker et al, 1982). Where residue have been incorporated before planting the next crop, grain yield was lower than where residues were removed or burned, resulting in N immobilization (Bahrani et al, 2002;Singh et al, 2004).…”
