A recent study has shed new light on the mechanics of keeping carbon in the soil and its implications for pasture management. The study, conducted by researchers at the University of California, Davis, found that certain types of soil fungi can help to protect carbon stored in the soil, preventing it from being released into the atmosphere as carbon dioxide.

Carbon sequestration, the process of storing carbon in soil, is becoming an increasingly important strategy for mitigating climate change. By storing carbon in the soil, we can help to reduce the amount of carbon dioxide in the atmosphere, which is the main driver of global warming.

The study found that certain types of soil fungi, known as arbuscular mycorrhizal fungi, can play a key role in carbon sequestration. These fungi form a symbiotic relationship with plant roots, helping plants to absorb nutrients from the soil. In exchange, the plants provide the fungi with carbon in the form of sugars.

However, the study found that the role of these fungi in carbon sequestration goes beyond this simple exchange. The fungi can also help to protect carbon stored in the soil, preventing it from being oxidized and released into the atmosphere as carbon dioxide.

This has important implications for pasture management. By promoting the growth of arbuscular mycorrhizal fungi in pastures, farmers and ranchers can help to increase carbon sequestration and reduce greenhouse gas emissions. This can be achieved through practices such as reducing tillage, reducing the use of synthetic fertilizers, and promoting the growth of diverse plant species.

Additionally, the study found that the type of soil management used can also have a significant impact on carbon sequestration. Soils that are managed for long-term carbon storage, such as those used in regenerative agriculture practices, tend to have higher levels of arbuscular mycorrhizal fungi than conventionally managed soils.

The new discovery on the mechanics of keeping carbon in the soil has important implications for pasture management. By promoting the growth of arbuscular mycorrhizal fungi and adopting soil management practices that promote long-term carbon storage, farmers and ranchers can help to increase carbon sequestration and mitigate climate change.
