The overall goal of SOIL-HEAL is to realise the potential of symbiotic soil fungi for sustainable agriculture, thereby addressing a key aim of the EJP Soil call to foster holistic and sustainable agricultural soil management practices. Most plants have coevolved with soil fungi to form root-fungal ("mycorrhizal") symbioses that are critical for regulating numerous ecosystem functions and services in natural and agricultural settings. An important feature of mycorrhizal fungi is their ability to form 'networks', which (in the broad sense) comprise three distinct elements: extra-radical mycelium, common mycorrhizal networks (CMNs), where a fungus links two or more plants, and community-level 'interaction networks' between and among mycorrhizal plant and fungal species. Despite the potential huge importance of mycorrhizal symbioses in agriculture, our understanding of the ubiquity and function of mycorrhizal fungal networks and their contribution to resilience of agri-ecosystems is remarkably poor. This is especially true under 'real-world' field conditions and in response to common management interventions used by farmers and land managers. To realise the potential of AM fungi for sustainable agriculture, SOIL-HEAL seeks to advance our mechanistic understanding of all three elements of fungal networks by determining:i) the properties of interaction networks of plants and fungi; ii) the production and turnover of extra-radical mycelium; iii) the relationships between fungal networks and key ecosystem functions, such as greenhouse gas production; iv) how management interventions influence the extent and function of fungal networks;v) whether fungal networks enhance the resilience of agri-ecosystems to climate extremes, especially drought, which is expected to increase in frequency and intensity with climate change.

soil - heal的总体目标是实现共生土壤真菌在可持续农业中的潜力，从而解决EJP土壤呼吁的一个关键目标，即促进全面和可持续的农业土壤管理实践。大多数植物与土壤真菌共同进化形成根-真菌（“菌根”）共生，这对调节自然和农业环境中的许多生态系统功能和服务至关重要。菌根真菌的一个重要特征是它们形成“网络”的能力，这种“网络”（广义上）包括三个不同的元素：超根菌丝体、普通菌根网络（CMNs），其中一种真菌连接两种或更多植物，以及菌根植物和真菌物种之间的群落水平“相互作用网络”。尽管菌根共生在农业中具有潜在的巨大重要性，但我们对菌根真菌网络的普遍性和功能以及它们对农业生态系统恢复力的贡献的了解非常少。这在“现实世界”的实地条件下以及农民和土地管理者使用的共同管理干预措施中尤其如此。为了实现AM真菌对可持续农业的潜力，SOIL-HEAL试图通过确定以下三个要素来推进我们对真菌网络的所有三个要素的机制理解：i)植物和真菌相互作用网络的特性；Ii)超自由基菌丝体的产生和周转；真菌网络与关键生态系统功能（如温室气体生产）之间的关系；Iv)管理干预如何影响真菌网络的范围和功能；5)真菌网络是否能增强农业生态系统对极端气候，特别是干旱的抵御能力，而干旱的发生频率和强度将随着气候变化而增加。
