How can the application of fungi enhance sustainable agricultural practices, and what are the potential benefits for crop yields, soil health, and ecosystem resilience?
Summary
This review explores the potential of fungi to enhance sustainable agricultural practices, through increasing crop yield, improving soil health, and providing ecosystem resilience. Arbuscular mycorrhizal fungi play a pivotal role in promoting plant growth by improving water and nutrient uptake, as well as triggering plant defence responses. Additionally, other fungal groups contribute significantly to increased crop productivity, soil stability, and the ability of agricultural systems to withstand the detrimental impacts of climate change. Additionally, fungi support circular economy practices by transforming agricultural waste into valuable resources, such as edible mushrooms, providing both environmental and economic benefits. Despite these advantages, challenges remain in the large-scale application of fungi in agriculture, particularly regarding inconsistent field-based and real-world results. Moreover, high costs and the need for specialised equipment limit accessibility for smallholder farmers. Future research should focus on understanding the discrepancies between controlled and field conditions, reducing implementation costs, and evaluating the ecological impacts of introducing non-native fungal species. By integrating fungi into agricultural practices, particularly with native species and climate-appropriate techniques, farmers can boost productivity while maintaining environmental sustainability. With proper support and education, fungi could become a cornerstone of sustainable agriculture in the face of climate change.
