Is enhancing SOC essential from the climate change point of view? If so, what are the main importance of soil organic carbon (SOC) from climate change point of view?
Yes, enhancing soil organic carbon (SOC) is considered essential from a climate change perspective. Increasing SOC can help mitigate climate change by sequestering atmospheric carbon dioxide, reducing greenhouse gas emissions, and improving soil health and water management.
Yes, enhancing Soil Organic Carbon (SOC) is essential from a climate change point of view for several key reasons:
1. Carbon Sequestration
SOC is a major component of soil organic matter and acts as a natural carbon sink.
Increasing SOC helps remove CO₂ from the atmosphere and store it in the soil, mitigating greenhouse gas levels.
Globally, soils hold 2 to 3 times more carbon than the atmosphere highlighting their importance.
2. Improves Soil Health and Resilience
More SOC improves soil structure, water retention and microbial activity making agricultural systems more resilient to climate extremes like droughts and floods.
3. Reduces Emissions
Practices that enhance SOC (like no-till farming, cover cropping and agroforestry) often reduce the need for synthetic inputs, lowering emissions associated with fertilizer production and use.
4. Supports Climate-Smart Agriculture
Enhancing SOC aligns with the goals of climate-smart agriculture—boosting productivity, adaptation and mitigation simultaneously.
5. Part of International Climate Agreements
SOC management is recognized under initiatives like 4 per 1000, the Paris Agreement and the UNFCCC as a tool for climate action.
Obviously, enhancing Soil Organic Carbon (SOC) is one of the cost-effective and natural strategy to tackle climate change, protect the environment, and promote agricultural sustainability. Soil actually stores more carbon than both the atmosphere and forests combined, making them essential carbon sinks. High SOC not only sequesters carbon but also prevents its release; when soils are degraded, stored carbon can quickly return to the atmosphere. Increasing SOC improves soil health by supporting microbial communities that create stable carbon storage. This process also contributes to regulate soil temperature, improve water retention, and enhance resilience to climate extremes.
С точки зрения климатического благополучия не менее важным является создание условий для ускоренной оборачиваемости СО2 в системе почва-растение-атмосфера, при этом пытаясь как можно дольше задержать его в двух компонентах агроэкосистемы - почве и растениях. Бесконечное накопление органического углерода в почве ограничивается большим количеством факторов - следовательно сам органический углерод почвы как конечная цель может иметь краткосрочный эффект. Важно, что бы в начале интенсивного распада органического вещества были вегетирующие растения, готовые эффективно перехватить выделяемый СО2 и замкнуть круговорот, тем самым возвращая углерод в почву в виде корневых экссудатов...
