Summary: Through a long-term field experiment, this study found that the combined use of organic manures and inorganic fertilizers, using integrated nutrient management (INM) strategy, significantly increased crop yield and soil organic carbon sequestration while reducing greenhouse gas emissions in a rice-wheat cropping system in the eastern Indo-Gangetic Plains (EIGP) of India.

Summary: Straw amendment and soil tillage affect SOC fractions and chemical components in Mollisols, with straw amendment increasing surface SOC and OC fractions, and soil tillage not significantly affecting the increased SOC and OC fractions. Straw amendment and soil tillage also alter the microbial community structure in the soil.

Summary: In this study, biochar was prepared using waste dander and CaSa(4) was generated on its surface to enhance soil carbon sequestration ability. The results showed that the application of Ca-BC reduced soil organic carbon mineralization rate, increased soil moisture content and organic carbon content. Bioinformatics analysis also revealed a shift in bacterial phyla with the application of Ca-BC.

Summary: This study investigated the effects of different nitrogen fertilizer application levels on straw yield and the influence of pyrolysis temperature on straw-derived biochar samples. The results showed that nitrogen fertilizer significantly increased straw yield, and pyrolysis temperature had a significant impact on the characteristics of the biochar samples. The treatment with a pyrolysis temperature of 500 degrees Celsius resulted in the highest nutrient content in the biochar samples.

Summary: In this study, we estimated the maize straw production and determined the appropriate straw return rate of different regions in China. The results showed significant differences in maize straw index and root-shoot ratio among different regions. The findings suggested that a reasonable straw return rate could achieve carbon balance in soil and increase soil organic carbon sequestration.

Summary: The voluntary carbon market for agricultural soil carbon sequestration is growing fast, but there is uncertainty regarding the equivalency of carbon credits generated in different programs due to inconsistent protocols. Scientists have a crucial role to play in guiding protocol development and conducting relevant research.

Summary: The study found that straw incorporation significantly increased SOC content and labile C fractions over a long-term experiment. The treatment with straw incorporation plus a moderate amount of potassium fertilizer (SI + K) showed the highest SOC content and labile C fractions, resulting in improved soil fertility and crop productivity.

Summary: The study found that adding organic amendments can improve the stability of POC and the sequestration of SOC, with a positive impact on increasing yields. Different sources of organic materials have varying effects on the stability of POC in mollisol, with woody plant material being the optimal choice for enhancing POC stability.

Summary: Forest type plays a key role in controlling soil organic carbon dynamics, interacting with shifts in litter quality. Microbial biomass carbon tends to decrease under litter input, with its variation strongly influenced by soil temperature and freeze-thaw events. The study highlights the importance of considering multiple mechanisms in understanding soil organic carbon dynamics in subalpine forests.

Summary: Large amounts of straw remained in the sugarcane fields after harvest. Indiscriminate straw removal or high amounts of straw on the field can negatively affect soil functions and crop yields. Leguminosae species grown during the sugarcane renewal period can potentially offset the negative implications of unsustainable straw management on soil and crop yield.
