Impacts of conservation agriculture on total soil organic carbon retention potential under an irrigated agro-ecosystem of the western Indo-Gangetic Plains

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

“…It is also inferred that SOC concentration decreased with increasing soil depth. 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.…”

Least limiting water range for two conservation agriculture cropping systems in India

“…A probable reason for similar surface BD in the PNB, PBB, and CT plots was the bed reshaping before cotton sowing (Das et al, 2013). Soil from the furrow was heaped over the beds and levelled by an iron bar passing over it (for smoothening of the beds).…”

Soil Organic Carbon, Carbon Sequestration, Soil Microbial Biomass Carbon and Nitrogen and Soil Enzymatic Activity as Influenced by Conservation Agriculture in Pigeonpea and Soybean Intercropping System

“…The higher SOC content in the plots under conservation tillage than conventional tillage plots might be attributed in part to less disruption of soil structure and aggregates (Das et al, 2013). During summer, conventional tilled soils tend to expose to sunlight which increases the loss of soil organic carbon due to increase in accelerate rate of decomposition of soil organic matter.…”
