• Crop Management for Soil Carbon Sequestration (2003, methodology): “The implementation of such technologies is needed in developing areas, especially in Saharan Africa, Asia, and South America (Lal, 2001).”
• Soil erosion response to climatic change and human activity during the Quaternary on the Loess Plateau, China (2006, neutral): “Accelerated soil erosion, in addition to causing on-site loss of topsoil and reducing the productivity of the land, also has serious offsite environmental effects (Roberts 1994; Morgan 1995; Lal 2001; Dearing et al. 2003).”
• Carbon emission from farm operations. (2004, background): “Lal (2000) reported that the magnitude of SOC loss due to historic erosion may be 3–30 Mg C/ha.”
• Can carbon sequestration markets benefit low-income producers in semi-arid Africa? Potentials and challenges (2007, methodology): “…cover cropping, crop rotation, application of soil amendments, and use of crop varieties that produce large root biomass and fix biological nitrogen (Reeves, 1997; Tiessen et al., 1998; Lal, 2000; Batjes, 2001; Schlesinger, 2000; Lal, 2002a; Lewandrowski et al., 2004; Bationo et al., this issue).”
• Policy and technological constraints to implementation of greenhouse gas mitigation options in agriculture (2007, background): “The consequences of soil erosion on CO2 emissions are highly uncertain (Lal, 2004a; Van Oost et al., 2004). C onservation tillage and zero-tillage are increasingly being adopted, thus reducing the use of energy and increasing carbon storage in soils. According to FAO (2001), the worldwide area under”
• Soil erosion and the global carbon budget. (2003, background): “Land use change from natural to agricultural ecosystems, ploughing and other soil disturbances deplete SOC pool onsite (De Jong et al., 1983; Janzen et al., 1997; Lal, 2000).”
• Global Potential of Soil Carbon Sequestration to Mitigate the Greenhouse Effect (2003, background): “It is because of the historic loss of SOC pool (by mineralization, leaching, erosion, or shift in vegetation), estimated at 30 to 60 Mg C/ha or 50 to 70% of the antecedent pool (Lal, 2000), that most agricultural and degraded soils now contain lower SOC pool than their potential determined by the sp”
• Tillage and residue management effect on soil properties, crop performance and energy relations in greengram (Vigna radiata L.) under maize-based cropping systems (2015, background): “The effect of conservation tillage on enhancing SOC sequestration has been reported by several researchers (Lal, 1994; Potter, Jones, Tolbert & Onger, 1997; Lal, 1999; Post & Kwon, 2000).”
• Soil carbon debt of 12,000 years of human land use (2017, background): “Scaling these limited point measurements to calculate a cumulative SOC loss for the world’s agricultural land has been difficult, with estimates ranging from 40 Pg C to over 500 Pg C (20).”
