“…Studies in Australia show large effects of tillage with 0.13% and 15.4% of applied NO 3 − lost as N 2 O from CT and NT, respectively (Dalal et al, 2003). Other studies have reported lower N 2 O emission under NT or RT (Almaraz et al, 2009;Mutegi et al, 2010;Pandey et al, 2012;Smith et al, 2012;Ussiri et al, 2009;Wang et al, 2011) or no difference in emissions (Bavin et al, 2009;Fuss et al, 2011;Garland et al, 2011;Lee et al, 2009;Oorts et al, 2007;Pelster et al, 2011 Six et al (2004) who found N 2 O emissions from NT declined with time.…”

“…Particularly for soilborne GHG emissions, which are also sensitive to environmental conditions, direct measurements are the most reliable (Pandey et al 2012). For this purpose, closed chamber systems are a simple, low-cost, and most applied technique (Parkin et al 2012).…”

“…It is found that frequency and timing of tillage also influence fluxes of soilborne GHGs. In the long term, the elimination of tillage reduced the emissions of CH 4 and N 2 O, but increased CO 2 from rice cultivation (Pandey et al 2012) as compared to conventional practice of regular tillage.…”

The term ''carbon footprint'' has evolved as an important expression of greenhouse gas (GHG) intensity for diverse activities and products. Widespread public acceptance and the ease of conveying information about GHG intensity with this term has also attracted scientists and policy makers to review and refine its calculations. Standard methods for carbon footprinting have been prepared, and sector-specific standards are under development. These standards direct the procedures to carry out carbon footprinting through life cycle assessment in conjunction with GHG accounting, classifes activities into three tiers based on the order of emissions. Agriculture is the largest contributor to anthropogenic emissions of greenhouse gases, so the quantification of different agricultural practices is essential for identification of more sustainable practices. Carbon footprinting has potential as a tool for assessing and comparing GHG performances of different agricultural products along with identification of points to improve environmental efficiencies. Case studies on the application of carbon footprinting to cultivation practices are increasing in the scientific literature, but the majority of studies do not comply with the standard three-tier methodology. This leads to nonuniformity among different studies and their comparisons. Hence, a standard guideline addressing carbon footprinting specifically for agriculture is essential for the effective application of this tool in the quantification of GHG intensity, mitigation of global warming, and adaptation against future climate change scenarios.

“…Rice is one crop often produced under a continuous monoculture practice; however, in this meta-analysis, paddy rice did not show significant difference of CO 2 emissions between tillage and no-tillage. Li et al (2010) and Pandey et al (2012) attributed the lack of difference to anaerobic soil conditions occurring under both practices.…”

Abstract. The management of agroecosystems plays a crucial role in the global carbon cycle with soil tillage leading to known organic carbon redistributions within soils and changes in soil CO 2 emissions. Yet, discrepancies exist on the impact of tillage on soil CO 2 emissions and on the main soil and environmental controls. A meta-analysis was conducted using 46 peer-reviewed publications totaling 174 paired observations comparing CO 2 emissions over entire seasons or years from tilled and untilled soils across different climates, crop types and soil conditions with the objective of quantifying tillage impact on CO 2 emissions and assessing the main controls. On average, tilled soils emitted 21 % more CO 2 than untilled soils, which corresponded to a significant difference at P <0.05. The difference increased to 29 % in sandy soils from arid climates with low soil organic carbon content (SOC C < 1 %) and low soil moisture, but tillage had no impact on CO 2 fluxes in clayey soils with high background SOC C (> 3 %). Finally, nitrogen fertilization and crop residue management had little effect on the CO 2 responses of soils to no-tillage. These results suggest no-tillage is an effective mitigation measure of carbon dioxide losses from dry land soils. They emphasize the importance of including information on soil factors such as texture, aggregate stability and organic carbon content in global models of the carbon cycle.
