Summary: Agroecological practices can increase soil organic carbon (SOC) stocks, but questions arise regarding the permanence of this storage in the context of climate change. Understanding SOC dynamics and its sensitivity to climatic events is necessary to anticipate carbon losses in terrestrial ecosystems. Investigating the potential limitations of carbon-storing soils under climate change is important for mitigating climate change impacts.

Summary: Soil organic carbon sequestration measures have different costs for farmers with diverse characteristics and locations, and a cost-effective analysis considering these heterogeneities is essential for developing effective public policies. Our research in France demonstrates that extending temporary grasslands is a low-cost option for carbon storage, but has limited potential, requiring the use of no-till and hedgerows to achieve ambitious carbon sequestration goals. Economic incentives prove to be more cost-effective than command and control measures due to heterogeneities among farmers, and a combination of agricultural and environmental policies is crucial for addressing climate change.

Summary: This study aims to investigate the extent and rates of soil organic carbon (SOC) sequestration potential under different climate and Sustainable Soil Management (SSM) practices in Finland. The study finds that increasing carbon input can promote SOC sequestration, but climate change reduces the potential. The findings are significant for increasing SOC sequestration efficiently in croplands.

Summary: This study aimed to investigate the sensitivity of parameters such as active carbon and nitrogen mineralisation potential to different agricultural management practices compared to total organic carbon and total nitrogen. The research found that active carbon and nitrogen mineralisation potential are valuable soil biochemical parameters providing detailed information on carbon and nitrogen dynamics, especially in terms of depth distribution and seasonal dynamics, making them more sensitive indicators for agricultural management practices.

Summary: The study of Soil organic carbon (SOC) pool has been extensively studied in the carbon (C) cycling of terrestrial ecosystems. However, in dryland regions, soil inorganic carbon (SIC) has received increasing attention due to various factors. The storage of SIC in dryland soils is a complex process that is influenced by multiple factors, and deeper layers of drylands have opened up several study aspects on SIC storage.

Summary: In the context of climate change, agroforestry systems are recognized as having the potential to increase carbon storage in agricultural areas. However, the carbon storage potential of agroforestry systems still needs to be accurately quantified, especially for hedges. This study aimed to add references to existing literature on soil organic carbon (SOC) storage near hedges and identify the main factors influencing its variability.

Summary: This study assessed the carbon sequestration and mitigation potential of afforestation scenarios with different species in the Province of Quebec, Canada. The results showed that afforestation with black spruce, white spruce, and jack pine can effectively reduce greenhouse gas emissions, and the choice of species and forest management strategy has a greater impact on carbon stocks than climate change itself.

Summary: This study evaluated the changes in agricultural production systems for major crops in the North China Plain from 2000 to 2016, identifying wheat, maize, vegetables, and oil crops as dominant crops with maize being the fastest-growing. The non-uniform agricultural landscape led to a decline in diversity indices. Fertilizers played a dominant role in impacting CF, which showed a decreasing trend, while nitrogen use efficiency, irrigation water use efficiency, and economic profit showed increasing trends.

Summary: Climate change and greenhouse gas emissions are important environmental issues in the 21st century. Soil carbon sequestration is considered the best solution for reducing CO2 enrichment in the atmosphere, and it is influenced by various management technologies. Farm yard manure application can sequester a significant amount of soil organic carbon, while legume-based crop rotation promotes carbon sequestration by accumulating carbon in macro-aggregates. Biochar has a positive effect on soil aggregation and carbon storage. Understanding the carbon stabilization mechanism through fractionation of different carbon pools is crucial for effective carbon management.

Summary: The role of soil organic carbon (SOC) sequestration as a 'win-win' solution to both climate change and food insecurity is critically examined in this article. The inclusion of SOC saturation in estimations significantly reduces the potential contribution of SOC sequestration to climate change mitigation, and the observed yield effects of increasing SOC are inconsistent. The article argues for a shift towards soil-smart agriculture that takes into account specific local conditions and quantifies multiple soil functions for land sustainability and food security.

Summary: Canada is a major wheat exporter with significant production challenges due to water scarcity. Effective water management practices, particularly in terms of fallow and irrigation, play a crucial role in increasing wheat yields. Simulation results suggest that in the Canadian Prairies, a water input of 400 mm is sufficient to achieve maximum yields.

Summary: This study analyzed temporal and spatial variations of topsoil organic carbon (SOC) in China's croplands based on 43,743 soil samples, revealing an increasing trend in SOC density from 1991 to 2012. The increase in SOC density was attributed to factors such as increased crop residue return, improved fertilization, and adoption of conservation tillage practices. However, some regions showed a decrease in SOC density due to water runoff, soil erosion, and low carbon input. The overall SOC stock in China's cropland increased by 260 Tg C from 1991-2001 to 2002-2012, potentially offsetting carbon dioxide emissions and reducing the overall net CO2 emissions in China.

Summary: Inhibitors are considered efficient in reducing nitrogen loss and improving nitrogen use efficiency, but their effectiveness varies across different agroecosystems. Urease inhibitors enhance crop yields and reduce ammonia emissions, while nitrification inhibitors are effective at reducing nitrous oxide emissions. The application of inhibitors is dependent on factors such as soil properties, climatic conditions, and management practices. Understanding the interactions between plant-soil-climate-management systems and different types of inhibitors is crucial for optimizing their effectiveness in reducing environmental losses and increasing productivity.

Summary: The soybean industry in Canada has faced setbacks due to climate risks and uncertainties in the global market. To adapt to climate change and make informed decisions, it is necessary to understand the future climate impacts on soybean production. The study found that as the climate warms, soybean production will expand further north and west, but in the mid-term, irrigation would be needed in semi-arid regions to mitigate increased precipitation deficits.

Summary: The conversion of forest to agriculture in higher latitude regions like northern Ontario, Canada is expected to increase due to warming. Minimizing soil organic carbon (SOC) loss is crucial, but there is limited understanding of best land management practices. This study measured changes in SOC after land conversion and used a model to assess the impacts of climate change on crop yields and SOC stocks. The findings highlight the potential role of pasture and crop diversification in avoiding SOC losses induced by climate-warming.

Summary: Methane emissions from liquid manure storage are currently estimated using a methane conversion factor (MCF) based on manure temperature inputs or air temperatures. However, differences between peak manure temperature and peak air temperature (T-diff) in warm seasons may result in inaccurate estimates. This study investigates the relationship between T-diff and the ratio of manure surface area to volume (R-s:v) and suggests using manure volume and surface area, along with removal frequency, to estimate T-diff and improve MCF estimates.

Summary: The Canadian Agricultural Nitrogen Budget for Reactive N (CANBNr) model was used to estimate the soil nitrogen balance in Canada from 1981 to 2016. The results showed that nitrogen input from fertilizer and nitrogen fixation increased at a faster rate than nitrogen removal in harvested crops, leading to an increase in residual soil nitrogen and nitrogen losses. The study also revealed regional differences in nitrogen losses, highlighting the need for further intervention.
