Effect of Long-Term Conservation Agriculture on Soil Organic Carbon and Dehydrogenase Activity under Maize-Based Cropping Systems

“…The finding of present study is in line with the published literature on depthwise distribution of SOC in crop lands (Mandal et al, 2013;Singh et al, 2015). This study corroborated the findings of Bhattacharyya et al, (2012) suggesting thereby the advantage of minimum soil disturbance (PB and ZT) and crop wise residue retention on soil surface.…”

Short-Term Effect of Conservation Tillage on Carbon Pools under Rainfed Cropping Systems of Central India

“…In the current investigation, SOC data revealed that tillage practices were significant difference similar result was found Bhattacharyya et al, 2012. Cropping system and interaction between tillage and cropping system did nothave showed any significant effect on SOC content.…”

“…Among the cropping systems compared, soybean + P. pea S + PP and M -G was recorded significantly higher OC concentration across the tillage in 0-5 cm depth, Das et al, 2013 found that cotton based cropping system had the highest root biomass addition in soil followed by maize based cropping systems. (Bhattacharyya et al, 2012) reported that in the Indian Himalayas, a reduction in tillage intensity led to a significantly larger SOC accumulation in the surface soil layer (0-5 cm), but not in the 5-to 15-cm soil layer after 6 yr of cropping. The data show almost similar trend was observed under in 5-15 cm depth.…”

Modelling soil water balance and root water uptake in cotton grown under different soil conservation practices in the Indo-Gangetic Plain

“…A higher Leaf Area Index (LAI) in the soil conservation practices than in the CT plots could be due to the compounded effects of many factors, such as an additional nutrient supply, decreased competition for resources due to a lower weed density, improved soil physical properties and water regimes, better radiation interception, water extraction, aeration and less evaporation in the soil conservation practices compared with the CT plots (Unger et al, 1998;Bhattacharya et al, 2012Bhattacharya et al, , 2013Das et al, 2014). Soil structure affects crop yield through a complex of root-based mechanisms, that in turn affect above-ground biomass (Passioura, 2002).…”
