    The role of arbuscular mycorrhizal fungi in soil carbon storage in forests.

    Neftaly: The Role of Arbuscular Mycorrhizal Fungi in Soil Carbon Storage in Forests
    Introduction
    Soil is the largest carbon reservoir in forest ecosystems, storing more carbon than trees and vegetation combined. Beneath the forest floor, a hidden alliance is at work—arbuscular mycorrhizal fungi (AMF) form symbiotic relationships with most forest plants and play a critical role in regulating how carbon moves and is stored in the soil.
    At Neftaly, we integrate natural solutions into our forest and soil management strategies. Recognizing the importance of AMF in soil carbon dynamics, we promote practices that restore and enhance these beneficial fungi to support long-term climate resilience and forest health.

    What Are Arbuscular Mycorrhizal Fungi (AMF)?
    Arbuscular mycorrhizal fungi are a group of microscopic fungi that colonize plant roots, forming specialized structures called arbuscules. In this mutualistic relationship:
    Plants supply AMF with carbon (in the form of sugars),
    AMF help plants absorb water and nutrients, especially phosphorus.
    AMF associations are ancient—over 400 million years old—and present in up to 80–90% of land plant species, including many forest trees.

    How AMF Contribute to Soil Carbon Storage
    Transfer and Stabilization of Plant Carbon
    AMF receive up to 20% of a plant’s photosynthetically fixed carbon.
    Much of this carbon ends up in fungal hyphae (filaments) that extend into the soil, where it contributes to soil organic carbon pools.
    Formation of Soil Aggregates
    AMF produce a sticky protein-like substance called glomalin.
    Glomalin helps bind soil particles together, forming stable soil aggregates that physically protect organic carbon from decomposition.
    Promotion of Root Biomass
    With improved nutrient uptake, trees and understory plants develop more extensive root systems.
    More root biomass and turnover lead to greater belowground carbon inputs.
    Influence on Microbial Communities
    AMF modify the microbial environment around roots (rhizosphere), often suppressing fast-decomposing organisms.
    This slows down carbon loss and enhances carbon stabilization.

    Neftaly’s AMF-Driven Forest Management Practices
    Neftaly actively promotes the role of AMF in forest restoration and soil rehabilitation through:
    Inoculating tree seedlings with native AMF before planting.
    Reducing soil disturbance (e.g., no-till, minimal compaction) to protect fungal networks.
    Applying organic composts and mulches that support mycorrhizal activity.
    Monitoring soil health using microbial DNA and glomalin content as indicators of AMF abundance.

    Field Success Example
    Location Practice Results
    Forest regeneration project – Eastern Africa AMF inoculated seedlings + compost +28% increase in tree growth, +22% rise in soil organic carbon (SOC) in 2 years
    Degraded woodland – Southern Africa Low-disturbance planting + organic mulch Greater fungal colonization and improved soil aggregation
    Agroforestry system – West Africa Mixed species cover crops with AMF associations Higher root biomass and enhanced SOC stabilization

    Why AMF Matter for Climate and Forest Health
    Long-term carbon storage: AMF help stabilize carbon in a way that resists loss through erosion or microbial decomposition.
    Drought and stress resilience: Healthier root-fungal networks improve forest survival in changing climates.
    Restoration success: Forests with healthy AMF populations establish faster and sequester more carbon.

    Conclusion
    Arbuscular mycorrhizal fungi are invisible allies in the fight against climate change. By enhancing root health, promoting stable carbon pools, and improving soil structure, AMF play a foundational role in forest carbon sequestration.
    At Neftaly, we’re unlocking the potential of these ancient fungi to build resilient, carbon-rich forest soils. Investing in soil biology is investing in the future of forests—and the future of our planet.

  • Soil fungi and their role in carbon sequestration in forest ecosystems.

    Soil fungi and their role in carbon sequestration in forest ecosystems.

    Soil fungi play a vital role in carbon sequestration in forest ecosystems. These microorganisms are key drivers of the carbon cycle, contributing to carbon storage and stability through various mechanisms.

    How Soil Fungi Contribute to Carbon Sequestration:

    • Decomposition and Carbon Storage: Fungi decompose organic matter, converting carbon into stable forms that can remain in the soil for long periods.
    • Mycorrhizal Associations: Mycorrhizal fungi form symbiotic relationships with plant roots, enhancing plant growth and carbon sequestration by facilitating nutrient exchange.
    • Soil Structure Improvement: Fungal networks improve soil aeration, water retention, and aggregation, promoting a healthier environment for carbon storage.

    Types of Fungi and Their Roles:

    • Saprophytic Fungi: Decompose organic matter, releasing carbon into the soil.
    • Symbiotic Fungi (Mycorrhizae): Form relationships with plant roots, enhancing nutrient and water absorption.
    • Ectomycorrhizal Fungi (ECM): Associated with higher soil carbon storage due to enhanced microbial carbon use efficiency.
    • Arbuscular Mycorrhizal Fungi (AMF): Contribute to soil carbon sequestration through extensive hyphal networks ¹ ² ³.

    Forest Ecosystems and Fungal Diversity:

    • Boreal Forests: Higher fungal diversity and species richness, with Basidiomycota dominating fungal communities.
    • Temperate Forests: ECM trees exhibit higher carbon storage due to enhanced microbial carbon use efficiency.
    • Tropical Forests: Symbiotic fungi, especially endomycorrhizal, dominate soil fungal communities ² ⁴.

    By understanding the role of soil fungi in carbon sequestration, we can develop strategies to promote their growth and enhance carbon storage capacity in forest ecosystems, ultimately contributing to climate change mitigation ¹.

  • The influence of mycorrhizal fungi on soil carbon storage in forests.

    The influence of mycorrhizal fungi on soil carbon storage in forests.

    Mycorrhizal fungi play a vital role in soil carbon storage in forests by forming symbiotic relationships with plant roots, enhancing nutrient exchange, and influencing soil carbon dynamics. Here’s how they impact soil carbon storage:

    Mechanisms of Carbon Sequestration

    • Enhanced Carbon Allocation: Mycorrhizal fungi receive 5-20% of plant carbon uptake, redistributing it into the soil, which supports fungal growth and contributes to stable soil organic matter formation.
    • Soil Organic Matter Formation: Mycorrhizal fungi improve soil structure by promoting aggregation, trapping organic matter, and preventing rapid microbial decomposition.
    • Carbon Stabilization: Fungal hyphae produce glomalin, a glycoprotein that binds soil particles and organic matter, creating a stable matrix resistant to microbial degradation ¹.

    Types of Mycorrhizal Fungi and Their Impact

    • Arbuscular Mycorrhizal (AM) Fungi: AM fungi increase soil aggregate formation, promoting soil carbon storage. However, some studies suggest they may also stimulate soil carbon decomposition.
    • Ectomycorrhizal (ECM) Fungi: ECM fungi can reduce decomposition rates by competing with free-living decomposers for nutrients, potentially increasing soil carbon storage.

    Factors Influencing Mycorrhizal Fungi’s Impact on Soil Carbon Storage

    • Mycorrhizal Type: Different mycorrhizal types (AM vs. ECM) can influence soil carbon storage through varying mechanisms.
    • Soil Properties: Soil nutrient availability, pH, and moisture levels can impact mycorrhizal fungi’s effectiveness in carbon sequestration.
    • Forest Management: Sustainable forest management practices, such as reduced tillage and organic farming, can support mycorrhizal fungi and enhance soil carbon storage ¹ ².
