Soil organic matter (SOM) is an important indicator of soil fertility, health and quality. For proper managements of agricultural fields, a long-term monitoring of changes in SOM contents in field and estimation of national accumulation of SOM are required. In this study, SOM in agricultural fields of paddy and upland systems were investigated from 2013 to 2020 for all administrative provinces of South Korea. Total field area was decreased by 4.8% and 9.1% in 2016 and 2020, respectively, compared to 2013. In paddy field, SOM content was 27.9 g kg -1 in 2013, which was gradually increased by 1.1% in 2020. Despite that SOM content increased at a field scale, national SOM accumulation in paddy fields decreased due to reduced paddy area. In upland fields, SOM content was gradually increased by 6.5% from 2013 to 2020. Though SOM content increased, however, SOM accumulation in the total agricultural field at national scale was not affect due to less area than paddy field area. Therefore, total SOM accumulation was continuously decreased from 69.2 Tg in 2013 to 65.3 Tg in 2020 mainly due to decreasing paddy field area. This study showed that in spite of the SOM increase of both fields, national SOM accumulation is decreased with significantly decreasing total field area. Therefore, it is required to increase SOM accumulation at a field scale through proper management of SOM. In addition, it is also necessary to conserve paddy fields to enlarge agricultural SOM at national scale.

“…The approaches differed in the two studies covering the livestock branch (studies 1 and 7). Bouazza et al [29] addressed enteric fermentation through an in-vitro fermentation Techniques other than no-till practice were successful in increasing SOC, such as residue retention and application of 1 t ha −1 of manure, which helped to improve SOC by +445% after 9 years of application in study 6 [34], and the rotation practice that made it possible to secure an increase of +11% to +11.7% in SOC depending on the rotation scheme in study 2 [30]. In study 10, no significant difference was found between crop rotation, no-till combined with residue retention at deep soil depths, and the conventional treatment [38].…”

North Africa (NA) is supposed to lower emissions in its agriculture to honor climate action commitments and to impulse sustainable development across Africa. Agriculture in North Africa has many assets and challenges that make it fit to use the tools of Climate-Smart Agriculture (CSA) for mitigation purposes. This study represents a first attempt to understand if CSA practices are sufficiently established in NA to contribute to reducing agriculture emissions. A PRISMA-inspired systematic review was carried out on an initial 147 studies retrieved from Scopus, Google Scholar, and the Web of Science databases, as well as from gray literature. 11 studies were included in the final analysis since they report the mitigation and co-benefits of CSA-based practices within NA. A bias risk was identified around the optimal inclusion of studies produced in French, and a specific plan was set for its minimization. Synthesis results revealed that most studies focused either on improving soil quality (nine studies) or managing enteric fermentation (two studies). The review revealed a poor establishment of the CSA framework in the region, especially in sequestering GHG emissions. A set of recommendations has been formulated to address the identified gaps from research orientations and organizational perspectives and empower the CSA as an ally for mitigation in north African agriculture.

“…Despite its presence in relatively small amounts in soils (1-6%), it has an overwhelming effect on many soil physical, chemical and biological properties, especially at the upper layer of the soil ( Brady and Weil, 2008; Magdoff and Van Es, 2009;Laghrour et al, 2016). Several studies demonstrated that SOM has an important influence on the improvement of soil structural stability and the reduction of erosion through strengthening bonds between aggregates able to resist to the stress caused by rapid wetting (Tisdall and Oades, 1982;Boyle et al, 1989;Lembaid et al, 2021). The SOM also enhances soil water infiltration and storage within soil by simulating microbial activity and increasing stable aggregates (Franzluebbers, 2002;Bessam and Mrabet, 2006; Nakamura and Touch, 2020; Lembaid et al, 2022).…”

The present study aims to compare two different methods for the determination of soil organic matter (SOM); the wet acidified dichromate oxidation methods Walkley-Black (WB) and the combustion's one (mass loss on ignition -LOI); in order to find out the best one in terms of suitability, environmentally-friendly, time-efficiency and economical benefit. Forty-five Moroccan soil samples (El Guich, Koudia and Merchouche area) from 0-20 cm depth with different classes, textures and organic matter contents were evaluated. According to the results, a strong linear relationship was observed between LOI-OM and WB-OM methods for all the sites. However, El Guich and Koudia recorded much larger regression coefficients (0.745 *** and 0.611 *** respectively) compared to Merchouche site (0.452 ** ). Therefore, the SOM by walkley-Black method can be easily calculated from the LOI method at 500±25 ºC for 2 hours using linear equation in order to minimize the analysis time and consumption of chemicals for routine laboratory. In addition, it was noticed that the SOM contents calculated by the LOI method are higher in Merchouche soils compared to that of WB due to the presence of a large amount of clay minerals in the Merchouche soils (43.9 < %clay < 56.1) in comparison with those of El Guich (5 < %clay < 7.5) and Koudia (16.1 < %clay < 20.4). This study revealed that both methods were reliable but W.B method was more accurate and suitable for calcareous soils and those with high clay contents. However, LOI method is an accurate and beneficial for non-calcareous soils with low clay content.
