Soil organic carbon (SOC) is one of the largest terrestrial carbon pools, playing a vital role in regulating a wide range of biological functions and ecosystem processes such as nutrient mobilization, cycling, availability, sequestration, and global carbon dynamics (Yang et al., 2022). The dynami...
additives, according to the quality difference between before and after oxidation of oxidant, calculate the amount of organic carbon, multiplied by the coefficient 1.724, the content of soil organic matter. Equipment: 2 equipment: 1/10000 analytical balance; electric bath (Shi Layu); test tube;...
The method described herein is an elemental chemical analysis to determine the noncarbonate (organic) carbon content of soil. It is designed to avoid errors that result from the presence of common contaminants in most soil classes. By multiplying the carbon content by a constant, the results may...

Conceptual and empirical advances in soil biogeochemistry have challenged long-held assumptions about the role of soil micro-organisms in soil organic carbon (SOC) dynamics; yet, rigorous tests of emerging concepts remain sparse. Recent hypotheses sugges
Increasing soil organic carbon (SOC) in croplands by switching from conventional to conservation management may be hampered by stimulated microbial decomposition under warming. Here, we test the interactive effects of agricultural management and warming on SOC persistence and underlying microbial mechanisms...

In agreement with this result, the soil organic carbon as well as the organic nitrogen were significantly augmented in this rice-pasture rotation system (Guo and Gifford, 2002; Pravia et al., 2019). In this trend, it has been reported that the incorporation of legumes after a period of ...
Soil organic carbon (SOC), total nitrogen (TN), and their ratio (C:N) play important roles in preserving soil fertility, and their values are closely related to fertilizer use. However, the overall trend and magnitude of changes in SOC, TN and C:N in response to chemical nitrogen fertiliz...
