Potential of Fungi for Carbon Sequestration
S oil is the most important terrestrial carbon sink as 80 % of carbon in terrrrstial ecosystem is stored in our soils. Soil fungi are the main regulator of this process. As decomposers, they produce organic materials with very long residence times in soil. Symbiotic fungi which colonise plant roots exert major control on the global carbon cycle. Despite its importance, fungi have not drawn the attention and hype that its powerful sequestration ability would suggest. In a time of damaging, worsening climate change, there has never been a greater need to appreciate fungi’s potential. As the “powerful knowledge nearly slipped through our fingers”. ‘Globally, at least 5b tons of carbon dioxide are sequestered within mycorrhizal networks each year, a quantity roughly equivalent to the amount of carbon dioxide emitted annually by the US.’ A powerful and underappreciated ally in the climate crisis? Fungi Mycorrhizal fungal networks are a major global carbon sink. When we destroy them, we sab...
