Nurturing with Nature: The Efficacy of Arbuscular Mycorrhizal Fungi Microbe for Cocoa Sector Environmental Management in Ghana
Summary
Researchers tested the efficacy of arbuscular mycorrhizal fungi inoculation for improving plant establishment and soil health in revegetation of degraded land, finding that mycorrhizal treatments increased plant biomass, root development, and soil nutrient cycling compared to uninoculated controls. The study supports the use of mycorrhizal bioinoculants as a nature-based tool for ecological restoration.
Abstract Despite the proven effectiveness of fertility-promoting microbes such as Arbuscular Mycorrhizal fungi (AMF) to minimize the adverse effects of environmental deterioration and climate change, there is limited understanding on its efficacy to improve cocoa resilience in Ghana. Cocoa mortality (70%) caused by climate change induced drought within two years of transplanting to the field is a major constrain to farmers’ productivity. We assessed the effect of morphologically identified AMF and K on the biochemical characteristics of cocoa and its field survival from 2019 to 2022. The AMF inoculum was prepared using the trap-culture technique. Multivariate Adaptive Regression Splines predicted leaf chlorophyll and Phosphorus uptake as the key factor influencing cocoa survival and resilience under field condition. The results have implications for cocoa breeding, productivity, sustainability of cocoa agricultural systems as well as K nutrition and AMF as bio-stimulant under drought conditions.

Unraveling the Effects of Arbuscular Mycorrhizal Fungi on Plant Growth, Nutrient Content, and Heavy Metal Accumulation in the Contaminated Soil: A Meta-analysis
This meta-analysis of 33 studies found that arbuscular mycorrhizal fungi significantly increase heavy metal accumulation in plant roots while reducing it in above-ground tissues, effectively acting as a biofilter. AMF-inoculated plants showed enhanced growth, biomass, and nutrient uptake on polluted land, suggesting a practical bioremediation strategy for contaminated soils.
Arbuscular mycorrhizal fungi attenuate negative impact of drought on soil functions
A meta-analysis combined with greenhouse experiments demonstrated that arbuscular mycorrhizal fungi promote soil aggregation, microbial biomass, and nutrient-cycling enzyme activity, effectively buffering soil functions against drought. This protective effect is relevant to microplastic concerns because soil health is increasingly threatened by plastic pollution, and understanding natural soil defense mechanisms is important for protecting agricultural ecosystems.
Symbiosis—A Perspective on the Effects of Host Traits and Environmental Parameters in Arbuscular Mycorrhizal Fungal Richness, Colonization and Ecological Functions
This review examines how host plant traits and environmental conditions regulate the richness, diversity, and ecological functions of arbuscular mycorrhizal fungi. The study highlights how these beneficial soil fungi contribute to sustainable agriculture through improved nutrient uptake, disease control, and stress tolerance, while noting that their effectiveness depends on multiple interacting factors.
Mycorrhizas for a sustainable world
This review synthesizes findings from the 10th International Conference on Mycorrhiza, covering how mycorrhizal fungal associations — present in over 80% of plant species — influence nutrient cycling, ecosystem resilience, and sustainability across scales from individual plants to global ecosystems. The paper highlights research priorities including mycorrhiza-based strategies for sustainable agriculture and restoration.
