Abstract:

Soil tillage can affect the stability and formation of soil aggregates by disrupting soil structure. Frequent tillage deteriorates soil structure and weakens soil aggregates, causing them to be susceptible to decay. Different types of tillage systems affect soil physical properties and organic matter content, in turn influencing the formation of aggregates. Retention of carbon (C) in arable soils has been considered as a potential mechanism to mitigate soil degradation and to sustain crop productivity. 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. 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 which was 22.63% higher over the conventionally tilled residue removed plots. Therefore, CA in rice-wheat system can help directly in building–up of soil organic carbon and improve the fertility status of soil.
