“…Similar results have been observed by Govaerts et al (2009) andAnyanzwa et al (2010). These authors report that, compared with other combinations of tillage with residue management, no-till practices with residue mulching promote the build-up of SOC in the surface soil and increase the distribution of soil aggregates, increase stability, and increase direct infiltration.…”

Crop residue retention is a key component of sustainable cropping systems. In recent years, retention of crop residue is a means of improving soil quality and nutrient capacity and reducing the adverse effects of residue burning. Maize-wheat rotation is a major double-cropping system practiced on more than one fifth of agricultural lands worldwide. Currently, more than 50 % of maize residues are retained immediately after harvesting. In China, this practice has beneficial effects on soil properties and productivity of the succeeding wheat crop. However, increasing the retention of maize residues without proper soil management has also led to a series of concerns, such as short-term nitrogen immobilization, rapid moisture loss, and high susceptibility to freezing during winter as a result of increased soil porosity. Therefore, other practices for maize residue retention are needed to promote wheat growth and the release of nutrients. This article reviews recent developments in China concerning the consequences of maize residue retention on the physical, chemical, and biological properties of soil quality and the growth, productivity, and quality of wheat. Major patterns of maize residue retention are discussed. In particular, this review provides three complementary approaches for maize residue management.

“…Conventional methods of crop establishment and residue harvested treatments add no more carbon which might be ascribed due to continuous nutrient removal from the plot. But, the level of soil organic carbon was not much decreased in conventional or residue harvested plots also as suggested by various literatures (Anyanzwa et al, 2010;Ghosh et al, 2010), it was found as similar to initial level and sometime slightly increased. This might be due to initial low carbon content in soil and maintaining by roots (Du et al, 2009).…”

“…The variation of soil organic carbon sequestration also depends on difference in microbial populace, moisture and temperature fluctuation (Govaerts et al, 2009). Residue retention and tillage has key role in soil carbon conservation (Duiker and Lal, 1999;Anyanzwa et al, 2010;Du et al, 2009;Corsi et al, 2012).…”

Soil organic carbon plays the crucial role in maintaining soil quality. The impact and rate of SOC sequestration in CA and conventional agriculture is still in investigation in this environment. A field experiment was initiated in 2011/12 and continued up to 2012/13 to compare the organic carbon buildup in the soil due to conservation and conventional agriculture. The soil organic carbon data represents the cumulative after five crop cycle. The treatments consisted conventionally tilled direct seeded rice followed by zero tilled wheat, conventionally tilled transplanted rice followed by conventionally tilled wheat, zero tilled direct seeded rice followed by zero tilled direct seeded wheat without residue retention, zero tilled direct seeded rice followed by direct seeded wheat with residue retention, permanent raised bed of rice followed by wheat without residue retention and permanent raised bed of rice followed by wheat with residue retention in randomized complete block design with three replications. About 4 t ha-1 of standing rice and wheat crop and about 70% residue of moongbean was retained for succeeding crop in retained treatments. Soil samples from each treatments were collected from two soil depths (0-20 and 20-40cm) and analyzed. Result showed that, soil organic carbon buildup was affected significantly by tillage and residue level in upper depth of 0-20 cm but not in lower depth of 20-40 cm. Higher SOC content of 19.44 g kg-1 of soil was found in zero tilled residue retained plots followed by 18.53 g kg-1 in permanently raised bed with residue retained plots. Whereas, the lowest level of SOC content of 15.86 g kg-1 of soil were found in puddled transplanted rice followed by wheat planted under conventionally tilled plots. Zero tilled residue retained plots sequestrated 0.91 g kg-1 yr-1 SOC in the year 2012/13 which was 22.63% higher over the conventionally tilled residue removed plots after five seasons of experimentation. Therefore, CA in rice-wheat system can help directly in building-up of soil organic carbon and improve the fertility status of soil.

“…The application of cattle manure on Chernozems increases the ratio of humic acids to fulvic acids, accelerates the formation of the labile humic substance and improves the formation of humus with a high degree of polymerized compounds (Nardia et al 2004). SOM is also positively affected by diverse cropping systems (Havlin et al 1990;Campbell et al 1998;Powell and Unger 1998;Anyanzwa and Okalebo 2010).…”

Kravchenko, Y., Rogovska, N., Petrenko, L., Zhang, X., Song, C. and Chen, Y. 2012. Quality and dynamics of soil organic matter in a typical Chernozem of Ukraine under different long-term tillage systems. Can. J. Soil Sci. 92: 429–438. Tillage has been reported to induce changes in soil organic matter (SOM) concentrations and quality. Conversion of plow-tillage to minimum till and no-till (NT) farming enhances the SOM pool. Enrichment of the SOM pool is essential for maintaining fertility of Chernozems, advancing food security, and improving the environment. The main objective of this study was to examine the effect of different tillage systems on the SOM concentration, its quality and dynamics including CO2 assimilation by heterotrophic bacteria and humus characteristics – the carbon (C) concentration in humic substances and the labile soil organic C fraction (SOCL) extracted with 0.1 N NaOH – as well as the molecular masses, spectroscopic parameters and physiological effects of humic acids on germinating pea (Pisum sativum L.) seeds. Our study was conducted on a long-term experimental site on a Haplick Chernozem in the Poltava region of Ukraine over a 10-yr period from 1996 to 2006. Results indicate that conversion from conventional to reduced soil tillage systems increased SOM concentrations in 0- to 10-cm soil layer and led to the accumulation of C in fulvic acids and humins. No significant differences in SOM storage in the 0- to 100-cm layer were observed among tillage systems. However, reduced tillage systems had a higher proportion of SOCL, a lower ratio of C in humic acids/C in fulvic acids and more humic acids with molecular masses from 110 to 2000 kDa. Our study demonstrated that the quality and dynamics of SOM are closely related to soil tillage practices.
