“…2c). If we consider an annual C stock increase rate equivalent to that obtained by Kazlauskaite-Jadzevice et al (2019;about 8 ‰), it could be calculated that an Arenosol could recover this stock in 117 years under appropriate practices. If calculated differently, i.e., not considering the same storage proportion as Kazlauskaite-Jadzevice et al ( 2019) but the same storage rate (a mean of +0.37 t C ha −1 yr −1 ), an Arenosol could recover its C stock in 131 years of storage.…”

Abstract. Few studies have focused on Arenosols with regard to soil carbon dynamics despite the fact that they represent 7 % of the world's soils and are present in key areas where food security is a major issue (e.g., in Sahelian regions). As for other soil types, land use changes (from forest or grassland to cropland) lead to a loss of substantial soil organic carbon (SOC) stocks and have a lasting impact on the SOC turnover. Here we quantified long-term variations in carbon stocks and their dynamics in a 80 cm deep Mediterranean Arenosol that had undergone a forest-to-vineyard land use change over a 100 years ago. Paired sites of adjacent plots combined with carbon and nitrogen quantification and natural radiocarbon (14C) abundance analyses revealed a C stock of 53 t ha−1 in the 0–30 cm forest soil horizon, which was reduced to 3 t ha−1 after long-term grape cultivation. Total organic carbon in the vineyard was dramatically low, with around 1 g C kg−1, and there was no vertical gradient as a function of depth. 14C showed that deep plowing (50 cm) in the vineyard plot redistributed the remaining carbon both vertically and horizontally. This remaining carbon was old (compared to that of the forest), which had a C:N ratio characteristic of microbial organic matter and was probably stabilized within organomineral associations. Despite the drastic degradation of the organic matter (OM) pool in this Arenosol, this soil would have a high carbon storage potential if agricultural practices, such as grassing or organic amendment applications, were to be implemented within the framework of the 4 per 1000 initiative.

Sequestering Organic Carbon in Soils Through Land Use Change and Agricultural Practices: A Review

Climate change vigorously threats human livelihoods, places and biodiversity. To lock atmospheric CO2 up through biological, chemical and physical processes is one of the pathways to mitigate climate change. Agricultural soils have a significant carbon sink capacity. Soil carbon sequestration (SCS) can be accelerated through appropriate changes in land use and agricultural practices. There have been various meta-analyses performed by combining data sets to interpret the influences of some methods on SCS rates or stocks. The objectives of this study were: (1) to update SCS capacity with different landbased techniques based on the latest publications, and (2) to discuss complexity to assess the impacts of the techniques on soil carbon accumulation. This review shows that afforestation and reforestation are slow processes but have great potential for improving SCS. Among agricultural practices, adding organic matter is an efficient way to sequester carbon in soils. Any practice that helps plant increase C fixation can increase soil carbon stock by increasing residues, dead root material and root exudates. Among the improved livestock grazing management practices, reseeding grasses seems to have the highest SCS rate. KEYWORDS agroecosystems, climate change, negative emissions technology, net zero 1 INTRODUCTIONExtreme weather events and global warming are inevitable because of anthropogenic emissions of warming gases (greenhouse gases, GHG) in the future [1] . Over recent decades, the atmospheric carbon dioxide concentration and the global air temperature (Fig. 1)have been rising linearly, and the records of the extreme temperature and precipitation intensity kept being rewritten. Negative CO2 emissions (i.e., CO2 removals) to lock CO2 up from the atmosphere through biological, chemical and physical processes are pathways to mitigate the global warming. Land management, soil management, bioenergy with carbon capture and storage, CO2 capture from ambient air, enhanced weathering and ocean fertilization are purported to be main potential approaches for CO2 removals [4][5][6] . Shepherd [7] categorized the CO2 removal techniques into three groups according to places where they are applied to (land or ocean) and predominant interventions and assessed the techniques in terms of their effectiveness, timeliness, safety, affordability and reversibility. The first group is to sequester more C into their natural sinks for a long period. The second is to apply enhanced weathering techniques in land and oceans. The third is to apply advanced technologies to capture and store CO2 directly elsewhere. The options also have been reviewed for their costs, potentials, side-effects, and innovation and scaling challenges for their implement [8][9][10] . Hepburn et al. [11] proposed 10 CO2 removal pathways: (1) chemicals from CO2, (2) fuels from CO2, (3) products from microalgae, (4) concrete building materials, (5) CO2-enhanced oil recovery, (6) bioenergy with carbon capture and storage, (7) enhanced weathering, (8) forestry techniques...

“…Finally, although arenosols lose a lot of carbon during cultivation (Fourie et al, 2005;López-Piñeiro, 2013), they have a high storage potential. Experiments implementing storage practices on arenosols (Kazlauskaite-Jadzevice et al, 2019) documented an increase of 40.2 to 45.6 t ha -1 (+ 13.4 %) and 39.4 to 49.0 t ha -1 (+ 24.4 %) in soil organic carbon stock (SOC stock) in the 0-30 cm soil layer in 20 years following cropland abandonment and a grassland management change, respectively. Arenosols, which have very low carbon stocks in cultivated systems, thus seem to be good candidates for the 4 per 1000 (4p1000)…”

“…We thus based our study on paired soils, measuring carbon contents and stocks, vertical and intra-horizon heterogeneity of carbon as measured by 14 C, and correlating the C:N ratio and radiocarbon (F 14 C). Finally, we applied a rate of carbon incorporation in our cultivated arenosol according to the proportions and rate put forward in the remediation study of Kazlauskaite-Jadzevice et al (2019).…”
