本論文は土壌有機物（SOM）の生態系における重要性と、炭素隔離を通じた気候変動緩和への寄与を総説する。SOMは土壌機能の基盤であり、持続可能な管理によって炭素吸収源として機能する一方、不適切な管理は炭素放出源となる。

06 Soil Organic Matter and Carbon Sequestration Ajay Kr. Bharti1, Sakshi Sandhya2 1Forest Research Institute, Dehradun 2Quantum University, Roorkee (UK) DOI : 10.5281/zenodo.20303405 1. Introduction Soil organic matter (SOM) serves as a cornerstone for the health, productivity, and ecological stability of terrestrial ecosystems. It consists of a diverse array of organic materials, including decomposing plant and animal residues, cells and tissues from soil biota, and organic substances synthesized within the soil matrix. SOM underpins nearly all key soil functions, such as nutrient cycling, moisture retention, structural stability, and the promotion of biological activity. Its presence significantly enhances soil fertility and undergirds robust plant growth by improving the physical, chemical, and biological characteristics of soils. In recent years, SOM has received heightened scientific and policy interest, not only for its essential role in sustaining soil health but also for its pivotal function in addressing global climate change. Carbon sequestration—the capture and long term storage of atmospheric carbon dioxide (CO₂)—has been recognized as a crucial approach for curbing increasing greenhouse gas emissions. Soils represent one of the planet’s largest carbon reservoirs, storing more carbon than the atmosphere and terrestrial vegetation combined, positioning them as a vital component of nature based climate solutions with significant potential for carbon mitigation. Nevertheless, soils are inherently dynamic and can operate either as a carbon sink or a source, contingent on land management practices, land use, and environmental factors. Sustainable management can promote the accumulation of organic carbon within soils, enhancing their role as a carbon sink. In contrast, unsustainable practices such as intensive agriculture, deforestation, and poor land stewardship can degrade SOM and release stored carbon back into the atmosphere, thereby intensifying climate change. Recognizing and managing this dual capacity of soils within the global carbon cycle is imperative for designing effective strategies that leverage soils for long term carbon storage while safeguarding their essential ecological functions.
