Organic carbon and total nitrogen stocks in a Vertisol following 40 years of no-tillage, crop residue retention and nitrogen fertilisation

Spatial and temporal variations of soil organic carbon and total nitrogen pools in the coastal reclamation area, eastern China

“…However, previous studies have found that there is an accumulation of SOC as a result of farming activities in the coastal reclamation area (Iost et al 2007;Liu et al 2013). Crop straw and application of fertilizers can interactively increase SOC and STN stocks (Dalal et al 2011). Plants improve the concentration of SOC in several ways (Galea et al 2000;Oades 1984;Zhang et al 2006).…”

Effect of Organic Inputs on Strength and Stability of Soil Aggregates Associated Organic Carbon Concentration under Rice-Wheat Rotation in Indo-Gangetic Plain Zone of India

“…Annual application of 16 t ha -1 of rice straw for 3 years decreased bulk density from 1.20 to 0.98 g cm -3 in the 0-5 cm layer on a sandy loam (Lal, 2000). Dalal et al, (2011) also reported the residues management practices had not significant influence on the bulk density of vertisol soil of Australia. Naresh et al, 2016 also reported that mean soil bulk density in the 0-to 20-cm soil layer of the FIRB with residue retention and ZT with residue retention plots was 12.4 and 6.8% lower, respectively (P < 0.05), than the CT plots.…”

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

“…After 22 years of no-till, Dalal (1992) found that soil total nitrogen decreased with the period of cropping irrespective of the tillage practices in subtropical cereal cropping in Australia. Similarly, Dalal et al, (2011) reported that tillage effects on soil organic carbon and soil total nitrogen were small following 40 years of no-tillage in Vertisols of Queensland region. Crop residue and N fertilizer interactively increased SOC and total N stocks in 0-10 cm depth and cumulative stocks at 0-20cm and 0-30cm depths.…”
