“…According to (Kundu et al, 2007), crop rotation is among the best management practices for increasing soil carbon stock. Similar results were obtained in the study done by (Gaiser et al, 2009, Abreu et al, 2011 in which SOC content in soil was increased due to different crop rotations. (Kaur et al, 2008).…”

“…Long term (five consecutive years) NT with adequate annual precipitation is required for NT cropping systems to increase SOC relative to that of CT (Six et al, 2004;Abreu et al, 2011). The Conservation Tillage Information Center (CTIC) provided data that address longer term (greater than 5 years) adoption of reduced tillage by IPCC climatic region and crop rotation (Eve et al, 2001).…”

“…The IPCC coefficients were developed based on climatic regions and broad land-use (crop rotation), which may be adequate to account for the variability in SOC storage. In addition, current research continues to find that no-till increases SOC sequestration relative to more intensive tillage operations (Abreu et al, 2011;Franzluebbers, 2010;Kumar et al, 2012;López-Fando and Pardo, 2011;Powlson et al, 2012;Varvel and Wilhelm, 2011;Virto et al, 2012).…”

“…The area of cropland by tillage intensity was derived from data provided by the Conservation Tillage Information Center (CTIC) who provided relevant data for tillage intensity by IPCC defined climatic region and crop rotation (Eve et al, 2001). Long term (five consecutive years) NT with adequate moisture is necessary for NT cropping systems to increase SOC relative to CT (Six et al, 2004;Abreu et al, 2011). Data for long-term NT adoption provided by the CTIC indicate that, while tillage intensity varies by cropland and climatic region, 1 to 12 percent of U.S. cropland (7.8 Mha total) was under NT in 1997 (Eve et al, 2001).…”

Background Existing research provides estimates of the biophysical potential for increasing soil organic carbon (SOC) stock, however additional research is needed to enhance our understanding of the economic potential for agricultural soils to offset or help reduce CO 2 emissions. This study derives the marginal cost to increase SOC sequestration by combining SOC sequestration potential estimates developed using the Intergovernmental Panel on Climate Change (IPCC) factors with an existing payment scheme that was designed to increase no-till (NT) adoption on U.S. cropland. The marginal costs of increasing SOC is a function of the amount of SOC that could be increased through NT and the expected cost to landowners of changing management to use NT. Results The variability in SOC sequestration rates due to different land-use, management histories, climate, and soils, combined with the 48 unique payment rates to adopt NT, yield over 5,000 unique marginal cost values for increasing SOC sequestration. Nearly 95 percent of the biophysical potential SOC sequestration increase on U.S. cropland (140.1 Tg CO 2 yr -1 ) could be captured for a cost less than $100 Mg -1 CO 2. An estimated 64 to 93 percent of the biophysical potential could be captured for less than the low and high estimated costs to capture CO 2 for geologic storage of $36.36 to $86.06 Mg -1 CO 2 , respectively. Conclusions Decreasing tillage intensity through adoption of no-till agricultural offers a cost-effective way to offset a portion of increasing global CO 2 emissions. This research demonstrates that increasing SOC stocks through NT adoption can offset CO 2 emissions at a lower cost than some other options for preventing CO 2 from entering the atmosphere.
