“…Meanwhile, C, LSPS, Co+S, BF, and HSPS stored similar values (p>0.05) and showed a range between 43.9 and 54.1Mg/ha. Mandal et al (2020) state that agriculture is a dominant land use and that carbon sequestration under different agroecosystems is an important option to fight climate change.…”

Soil is an important carbon reservoir as it can store twice the amount that atmosphere does and three times the biomass, which makes it a key component for climate change (CC) mitigation projects. It is important to know the potential of soil organic carbon storage (SOC) in the main uses of the soli and their expected dynamics due to potential use changes. SOCS is estimated in 7 of the dominant land use systems in the area of the study, with 5 replicas as follows: 1) banana with shade (SAF+banana); 2) cocoa with shade (Ca+S); 3) citrus (C); 4) low silvopastoral system (SSPB); 5) high silvopastoral system (SSPA); 6) gallery forests (BG); and 7) bush forest (MM). SOC concentration was analyzed in samples composed of 25 soil sub-samples per plot, and the DA was estimated with the cylinder method in a simple per plot. All land uses studied can mitigate CC when storing SOC. BG was the system that showed the highest carbon storage. On the other hand, SAF+banana stored the least SOC (72,7 vs 33,4Mg/ha, respectively). Changes in land use can cause CO2 emissions or an addition in carbon fixation. Changes in land use that increase SOC allow CC mitigation, which makes them feasible for funding, thus allowing an improvement in the livelihood of local producers.

“…The addition of fresh organic amendment into the soil is known as soil priming (Kuzyakov et al 2000). The soil priming usually causes carbon dynamics (Mandal et al 2020). Based on the National Cropland Data Layer of the National Agricultural Statistics Service, Flathers and Gessler (2018) extracted five crop species to develop a SOC content map of major cereal crop-growing regions in the northwestern United States.…”

“…Soil carbon is the critical component of soil fertility to sustain plants, animals, and humans (Rumpel et al 2018). The spatial distribution of soil carbon not only helps in figuring out soil organic carbon (SOC) content/stock over regions but also contributes to supporting Earth system modeling and sustainable land management (Dignac et al 2017, Mandal et al 2020). However, precise quantification of global soil carbon stock remains challenging mainly because of sparse soil observations over the world, especially at deep depths, also leading to the great uncertainty in terrestrial carbon stock estimation (Piao et al 2009).…”

“…Most cropland worldwide is distributed in the area with flat terrain, thus the observed heterogeneities for commonly involved natural factors (such as topography) are limited (Stevens et al 2014). Moreover, human activities such as irrigation, crop rotation, and fertilization have a greater impact on soil qualities (Mandal et al 2020), while obtaining quantitative agricultural management information is difficult. Using weakly related environmental covariates to represent the characteristics of the spatial distribution of soil carbon in agricultural areas paints only a partial picture (Hamzehpour et al 2019).…”

Cropland soil carbon not only serves food security but also contributes to the stability of the terrestrial ecosystem carbon pool due to the strong interconnection with atmospheric carbon dioxide. Therefore, the better monitoring of soil carbon in cropland is helpful for carbon sequestration and sustainable soil management. However, severe anthropogenic disturbance in cropland mainly in gentle terrain creates uncertainty in obtaining accurate soil information with limited sample data. Within the past twenty years, digital soil mapping has been recognized as a promising technology in mapping soil carbon. Herein, to advance existing knowledge and highlight new directions, the article reviews the research on mapping soil carbon in cropland from 2005 to 2021. There is a significant shift from linear statistical models to machine learning models because nonlinear models may be more efficient in explaining the complex soil-environment relationship. Climate covariates and parent material play an important role in soil carbon on the regional scale, while on a local scale, the variability of soil carbon often depends on topography, agricultural management, and soil properties. Recently, several kinds of agricultural covariates have been explored in mapping soil carbon based on survey or remote sensing technique, while, obtaining agricultural covariates with high resolution remains a challenge. Based on the review, we concluded several challenges in three categories: sampling, agricultural covariates, and representation of soil processes in models. We thus propose a conceptual framework with four future strategies: representative sampling strategies, establishing standardized monitoring and sharing system to acquire more efficient crop management information, exploring time-series sensing data, as well as integrating pedological knowledge into predictive models. It is intended that this review will support prospective researchers by providing knowledge clusters and gaps concerning the digital mapping of soil carbon in cropland.

“…The N dynamics affects C sinks through the processes of biological, physical and chemical about fine root turnover, litter decomposition, soil respiration and photosynthetic characteristics ( Mandal et al, 2022 ). Terrestrial C–N interactions are extremely important in determining the long-term sustainability of C sinks in land ecosystems ( Deng et al, 2016 ).…”

Field cultivation practices have changing the carbon and nitrogen cycles in farmland ecosystem, soil organic carbon (SOC) and total nitrogen (TN) were the important parameters in maintaining soil quality and increasing agricultural productivity, however, N application’s effects on the SOC and TN storage capacity under intensive wheat-maize cropping system remain unclear. Therefore, we investigated the characteristics and relationships of SOC and TN for wheat-maize cropping system under nitrogen treatments. In doing so, continuous applications of four nitrogen application rates were examined: 0, 180, 240 and 300 kg ha−1 (N0, N180, N240 and N300, respectively). Wheat yields under N180 and N240 were significantly higher than that under N300, while the maize yields under N180, N240 and N300 were significantly higher than that under N0 by 79.79, 85.23 and 86.85%, respectively; the TN content and storage were significantly higher under N240 than that under other N levels in 40–60 cm soil layer after wheat growing season; the SOC content and storage under N180 and N240 were significant higher than that under N300 in 20–40 cm after maize growing season. The correlations between SOC and TN contents (or storage) were stronger after wheat planting than maize planting. These findings provide a basis for further studies on the effect of long-term N application on SOC and TN storage, crop quality and nitrogen use efficiency under wheat-maize cropping systems.
