Soil carbon is a critical component of soil health and plays a crucial role in supporting plant growth and productivity. It refers to the organic matter, including dead plant material and microorganisms, in the soil. Soil carbon is formed through the process of photosynthesis, where plants convert atmospheric CO2 into organic matter. The presence of a healthy soil carbon pool is essential for maintaining soil structure, fertility, water retention capacity, and biodiversity. Additionally, soil carbon helps mitigate climate change by reducing atmospheric CO2 levels through carbon sequestration. Maintaining and increasing soil carbon levels is essential for sustainable agriculture and long-term soil health.
What happens when carbon in soil reduces?
- Soil structure degrades and becomes less porous.
- Soil fertility decreases and plant growth is inhibited.
- Soil biodiversity is reduced, leading to fewer beneficial microbes and insects.
- Soil becomes more susceptible to erosion and degradation.
- The ability of soil to retain water decreases, leading to increased runoff and decreased water infiltration.
- Soil carbon sequestration is reduced, releasing CO2 into the atmosphere.
- Agricultural yields may decrease, leading to decreased food security.

How To Increase Organic Carbon At Your Farm?
- Incorporate organic matter into soil through composting or adding mulch.
- Minimize tillage and promote conservation tillage practices to preserve soil structure and protect against erosion.
- Plant cover crops and rotate crops to diversify soil biology.
- Implement agroforestry practices by incorporating trees into farming systems.
- Use natural farming practices instead of conventional agricultural practices.
- Promote photosynthesis through proper plant nutrition and sunlight.
- Implement regenerative agriculture practices to enhance soil health and carbon sequestration.
