Summary: Considerable advances have been made in the assessment and mapping of soil organic carbon stocks. However, the rates of change in carbon stocks are influenced by various factors and need to be quantified. This study found that sandy soils under cultivation and forests have different organic carbon stocks. Factors such as tillage, irrigation, and nitrogen applications contribute to the decline in soil organic carbon stocks. Afforestation of abandoned cultivated fields can increase soil organic carbon, but it is still lower than soils under forest that have never been cultivated.

Summary: The study found that irrigation in New Zealand significantly reduced soil carbon and nitrogen stocks, with greater losses observed at greater durations of irrigation and lower aridity levels. The impact of irrigation on soil C and N was negatively related to aridity, with increasingly significant carbon losses observed at sites with higher precipitation levels. The results suggest that a new equilibrium may be reached with lower carbon stocks in irrigated grasslands compared to unirrigated grasslands.

Summary: The aim of this study was to understand the impact of the combination of no-till and cover cropping on soil organic carbon (SOC) and soil respiration. The results showed that for soils with high initial SOC contents, there was no significant difference in SOC and respiration between the conservation practices and conventional practices. However, for soils with low initial SOC contents, the conservation practices significantly increased SOC and respiration.

Summary: The study found that nitrogen addition significantly increased global SOC content, with the increase amplified over time in both organic and mineral soil layers. The increase mainly resulted from enhanced plant carbon input to soils coupled with reduced carbon loss from decomposition.

Summary: This study assessed the role of tree species in carbon storage and soil enrichment in the eastern plateau and hill region of India. It found that tree plantations significantly increased soil organic carbon, nitrogen, phosphorus, and potassium, but decreased pH and bulk density. Gmelina arborea had the highest carbon density and carbon sequestration potential, followed by Eucalyptus tereticornis, Cassia siamea, and Leucaena leucocephala, indicating their suitability as atmospheric carbon reducers.

Summary: The increase in soil organic carbon (OC) in China over the past two decades suggests that atmospheric carbon dioxide is being sequestered into the soil, mitigating climate change and improving soil health. However, there have also been reports of soil pH decrease nationwide, which may negatively impact soil quality for food production and the environment. This study investigates the relationship between soil OC and pH using large-scale soil survey data from two provinces in China and finds that the changes in OC and pH are significantly correlated, with increased soil nitrogen content as the linking factor. The decrease in pH is particularly significant in the eastern region of China, where soils are more neutral in pH. The study recommends exploring alternative methods of carbon sequestration in soil to avoid potential acidification effects caused by excessive nitrogen application.

Summary: Organic amendments significantly increased soil organic C stock in saline paddy fields, with biochar treatment showing the highest increase. However, rice straw and organic fertilizer were found to be more effective in improving soil aggregate stability compared to biochar. This research highlights the importance of organic amendments in enhancing soil quality and carbon sequestration in saline-alkaline soils.

Summary: The study found that long-term phosphorus fertilizer and irrigation treatments can increase carbon storage in grasslands, with increased decomposition rates in fast cycling carbon to offset input increases. Increasing phosphorus fertilization also led to increased decomposition rates in the slow pool.

Summary: Based on a comprehensive investigation of 7.5 million soil samples from 2209 counties in China, this study estimates the soil organic carbon stock in China's croplands. The results show that China's croplands store a total of 4.53-4.98 Pg organic carbon. The increase in soil organic carbon stock is mainly driven by the increasing inputs of crop residue and livestock manure, and the soil organic carbon storage is projected to reach 6.98-7.98 Pg by 2060.

Summary: Tackling the global carbon deficit through soil organic carbon sequestration in agricultural systems has been a recent focus. However, there is still a lack of comprehensive understanding of on-farm SOC sequestration potentials in order to derive effective strategies.

Summary: The study estimated carbon sequestration potential of Q. leucotrichophora-based traditional agroforestry systems and natural forest in Garhwal Himalaya, India. It found that higher elevations stored more carbon and soil organic carbon showed a negative relationship with depth and elevation. The study suggests that the agroforestry systems can be models to combat increasing carbon and stabilize climate change in the Central Himalayan region.

Summary: Increasing elephant populations result in a loss of tree carbon storage, but contrary to the second hypothesis, soil organic carbon stocks actually increase with higher elephant densities. This increase in SOC is mainly found in the topsoil and is due to the formation of SOC from woody biomass.

Summary: Organic agriculture can lead to higher concentrations and production rates of soil CO2 compared to no-till agriculture. However, the effect of agricultural management techniques on soil CO2 is not well understood.

Summary: This study analyzed the spatial heterogeneity of soil organic carbon (SOC) in Guizhou Province and found that the content of SOC decreased from west to east, with low-value areas mostly located in the south and north regions. Altitude, slope gradient, and rock exposure rate had significant impacts on SOC levels. The findings of this research are important for formulating carbon sink strategies.
